Condensation Control On Board in the Pacific North West

29 May 2016
John
This morning I answered an email inquiry from some Aussies who are planning to head to Alaska. They had been reading our blog and had questions about condensation control. My response ended up being so long and detailed that I thought it might be a good idea to post it here for others who might be headed that way.

Hi Kate and Paul,

Congratulations on your impending Alaskan adventure. It is the most spectacular place we visited in our 7 years cruising. We did not make it to Patagonia which is supposed to provide similar scenery but Im not sure it has the same wildlife.

Sometimes NZ tries to pitch itself as being like the Pacific NW, in terms of scenic beauty but it does not come close to the real thing. If you have been to Milford sound think about that on a scale that is ten to 100 times bigger, both in square miles and height.

If you have been through our blog you know how we lucked out and were given an excellent strategy for getting to AK through the eternal string of gales that cross the north pacific. We know people who left Kauai within days of when we did and turned for Seattle or Vancouver and were clobbered by riding in gales for days. One guy with a boat like ours used his Jordan drogue. We sold ours unused when we got to Seattle. That was one of the goals for our circumnavigation.

Condensation is a problem at those latitudes for un insulated boats and most of the fixes we know about work fine in port, where you have electric power, but are not usable on the hook. We ended up buying a dehumidifier here in Seattle that runs most of the time. It eliminates the sweating in the cabinets and most of the condensation on ports but using the propane stove generates water vapor that the dehumidifier does not eliminate before it condenses. I dont remember us having similar problems with condensation while we were in Tasie but even the southern tip of Tasmania is 20 degrees closer to the equator than Kodiak.

We have friends who have worked out other solutions for their boats. Some have used plumbing type heating tapes in troublesome areas or heat bars intended to keep closets dry on shore. We never needed to do that.

We had three very annoying places for condensation.

1. The overhead hatches in our main cabin and in our sleeping cabin get condensation on them that can drip on your head either at dinner or when you are sleeping. In the sleeping cabin, and for two small overhead hatches in our pilot house, I had stiff foam inserts made that insulate the hatches and cut off access of damp air to their cooler surfaces. The inserts are a 100% cure for that problem.

We have wood frame insect screens and I just took those to a foam shop and had them cut the inserts to match plus a couple of mm to make the fit snug. The inserts are made from a dark grey closed cell foam and are holding up quite well after two Seattle winters.

An insert like that would darken the main cabin too much so for that hatch I used a 3m product that is designed to weatherproof windows in homes in cold climates. I got it on Amazon http://www.amazon.com/3M-Indoor-Insulator-Kit-2-Window/dp/B000AXXCUC?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_search_detailpage

There are several different size packages so you just make your best guess as to which is appropriate for your application. It consists of a roll of double sided tape and a large sheet of clear plastic that looks like saran wrap. You put the tape around the window/port you want to protect then stick the saran wrap to the tape as wrinkle free as you can manage. Then warm the plastic with a hair dryer or heat gun and the remaining wrinkles disappear

This plastic film solves the problem of condensation on those surfaces. The disadvantage is that you cant open the port if you get some nice weather.


2. We have one troublesome port (stainless steel) in our sleeping cabin. I think it sweats because of the water vapor we exhale at night and that particular hatch is farthest from the dehumidifier so the exchange of air is not adequate to keep the air up there dry enough. I covered it with the 3m plastic wrap and that seems to do the trick while not an entirely ideal cosmetic solution.

All the rest of our ss ports are adequately kept dry by our dehumidifier.

3. We have a pilot house boat and there are lots of large windows. The 3m product works for those just fine. It takes me a few hours in the fall to put the plastic on and a few minutes in the spring to remove it. The special tape does no damage to the surfaces it is used on.

We also had problems with condensation on the bottom of our 6" latex mattress. None of the other cushions had the problem but the mattress had it big time. I could stick my hand under in an feel water. \\

At first we battled it by pulling the mattress halfway out of the bunk a couple of times a week and moving the dehumidifier up to that cabin for the day.

At last year's seattle boat show I found a better solution that works very well. The product is called "Hypervent".

Here is a link to it on Defender

http://www.defender.com/product3.jsp?path=-1%7C2276179%7C2276186&id=1818021

and a link that shows the detail a little better on Fisheries supply here in Seattle

http://www.fisheriessupply.com/hypervent-hypervent-mattress-pads

the photos on the fisheries supply page give you a better ide of what the stuff is like. Its a sheet of flexible plastic with a web of short bent pieces of what looks like monofilament fishing line on one side. When its under the mattress it provides an air space for ventilation and the movement of the bodies on the mattress seems to work to pump air through the space. It works very well. It makes it a little more difficult to get into the lockers under the bunk. I improved access by cutting it into three pieces that roughly correspond to the lids on our lockers. So I can pull out the hypervent that is covering the locker of interest and replace it when I am finished. Marking it so the correct orientation is obvious helps a lot. Sharpie works fine.

Its priced by the foot and it cost me about $130 (including sales tax) for our double bed sized mattress. Make a paper pattern next time you have your mattress out of the bunk.

When we first bought our boat we installed a small propane heater which was more than adequate for weekends in San Francisco. It also took the chill off the cabin on our passage to Alaska and while we were anchored in Alaska. It makes water vapor that is not all vented and it consumes a lot of propane so we have to be careful about how much we use it.

When we got to Kodiak we bought a 1500 watt 110 volt electrical heater that was more than enough to overheat the cabin in the Alaskan summer and it helped dry the cabin a lot. Within two days of being docked most of the condensation was gone but it returned promptly once we left the marina.

If your boat is set up for 220 volt shore power you might just buy an extension cord when you get to alaska and use that to run a heater. We had a breaker box made in NZ that was on the end of an extension cord and used that to run a smart charger when we were in 220v countries. We keep the batteries up and used all our US applicances off the inverter.

We have a big (100AMP) charger in our inverter but I added a Xantrex Tru charge 40A charger. It has a smart inlet circuit that figures out what AC power it is seeing and adjusts accordingly. So when plugged into 220 v power in other countries our charger just started making 12 DC. It also works here in the US where we used it to keep the batteries up while I took the inverter in for service.

The US is a lot more casual about the AC power systems on your boat and you will not be required to have your electrical system inspected by a licensed electrician before you can connect to 100v shore power. Of course the connectors you need are all different that what you already have but there is an excellent boat store in Kodiak where you can get that sort of stuff for reasonable prices.

Another very effective tool for keeping un insulated boats dry is a diesel heater. You can spend a fortune on those but a lot of people use the open flame type heaters and they are somewhere just north of $1000 US to install. We decided against the option for several reasons. One is that the installation requires cutting a 5 inch hole in the cabin top and I not emotionally prepared for that. Placement in the cabin is important to proper functioning and the things get really hot and are known to damage foul weather gear and human skin when the come in contact. Even the guys who sell the things here in Seattle tell you that your boat will always smell of diesel if you have one of these heaters in constant use. That seem to be true for the boats I have visited with a diesel heater.

The final nail in the diesel heater coffin was that it end up costing a lot more to operate than electrical heat here in Seattle where we settled. The diesel heaters are rated by how much fuel they burn, not how much heat they put into the cabin. The manufacturers wont tell you what percentage of the heat goes up the stack but Ill bet it is at least 50%. Electrical is less per BTU and all the heat stays in the cabin. Here in seattle we have a lot of hydroelectric power so our rates are cheaper than many places. As you pass through Alaska, Canada, and the Pacific NW of the US you will probably not be staying in any marina long enough to end up getting billed for electric power so electric heat would be essentially free.

Your ac unit may be enough to dehumidfy your cabin but if you need to buy one they are cheap here. appliances in general are really cheap in the US compared with Australia and NZ and even Canada is not too bad these days because of the exchange rate. here is the one we bought and it works fine

http://www.homedepot.com/p/GE-30-Pint-Dehumidifier-ADEL30LR/203661853

I have to empty the bucket once per day during most of the year and when we travel away from the boat for a week or more I put it on the cutting board over the galley sink and install a hose that leads the output into the drain. It will run indefinitely in that configuration and we always come home to a dry boat. In the Caribbean side of the Panama canal the marina (Shelter Bay) rents dehumidifiers for boaters that leave their boats for a while. Those you dont get that service frequently come back to boats that are almost totally destroyed by mildew.

Living on your boat in steamy places like Panama is not a problem since the boat is well ventilated and still hotter than hell.

One last bit of info that might be helpful.

The best place in Alaska we saw was Prince William Sound. Despite its association with the Exxon Valdez disaster it is incredible for its stunning natural beauty. There is only one cruising guide for the sound and it is full of excellent information and very poorly organized.

Its also expensive, even for old editions.

http://www.amazon.com/Cruising-Guide-Prince-William-Sound/dp/1877900176/ref=sr_1_1?ie=UTF8&qid=1464533322&sr=8-1&keywords=cruising+guide+to+prince+william+sound

Shop around if you want to buy one. I dont remember where I found ours but it was way cheaper than Amazon.

The primary problem with the book is that its not well organized with overview charts that help you find the pages you need. So one of the things I did during bad weather in PWS was enter the waypoints for the anchorages in the guide in open CPN and labeled them with the page numbers of the description in our edition of the guide. I can email the file with the waypoints but not sure it will align with other editions.

I have loaned our copy to some friends who are headed to AK this summer. Ill write to them and ask which edition it is and let you know. It looks like the one in the pic in the Amazon listing.

The primary author died and his wife has put out new editions so I dont think it will make much difference if you have an early one or a more resent one.. The only reason I know to be particular is if you want to use my waypoints. Even without my waypoints you can find your way around. there are hundreds of secure anchorages. We were in one anchorage toward the center of the sound waiting out bad weather when the buoy reports said it was blowing 45 kts out in the sound and our wind generator was not even rotating.

You need to be patient with the weather up there. You will have two or three days of absolutely shitty weather followed by two to three days of glorious weather. Its quite a bit easier to forecast in Alaska than at similar latitudes in NZ and Oz so you can plan your marina days a little better.

Once you leave PWS and head into the inside passage you will have left the best part of Alaska and the part that most cruise ship passengers never see. The parade of cruise ships moving up and down the inside passage is impressive and the thousands of people on these ships see scenery they will remember for the rest of their lives, but they miss the best part. Our trip down the inside passage was anticlimactic after PWS. There are more active glaciers in College Arm in PWS than the entire glacier bay national park at the northern end of the inside passage.

You have to have reservations to take your boat into Glacier National Park/. We blew off our reservations when we realized how much better PWS was.

Hope this helps. It turned out to be a lot longer than I planned so I think Ill post it on the blog, too.

Kayak Tour Up Through the Ballard Locks

06 June 2015 | Ballard Locks, Seattle
John
Shawn and I have been talking about buying some kayaks to carry on deck when we visit the many anchorages to enjoy here in the Pacific Northwest.

Since there is a business that conducts Kayak Tours located right here in our marina we signed up for a three hour paddling trip up through the hundred year old Ballard Locks and into the lakes that form part of Seattle's character.

The locks were originally built to enable the transportation of logs and coal through the lakes and down to Puget sound. Now their primary functions are to allow large number of pleasure boats to move between the lakes and the sound and also to allow the fishing fleet access to the services long the canal that hand maintenance on the big fishing boats like are seen on the TV show "Deadliest Catch".

Doing the tour gave us a chance to test drive a two person sit-inside kayak.

The tour took three hours and was a lot of fun. We even got a discount because we are marina residents. Our guide was cheerful and informative.

Once we get our own Kayak this tour will probably be one we will recreate for ourselves and make the tour long enough to visit the pubs and restaurants that line the shore of the lakes and the canal that connects them.

The photo at the top of this post shows the locks. I snagged the pic off the internet. You can see the two chambers. The larger chamber is toward the top of the photo and the much smaller one, that we went through, is next to the damn that controls the level on the lake side of the locks. There is also a fish ladder on the left side of the damn with viewing windows under the water where visitors can watch the salmon working their way upstream to spawn.

Our First Weekend Crusie in Puget Sound

06 June 2015 | Blake Island, Puget Sound
John
The weather has finally gotten nice enough that we were willing to leave our slip in the marina and venture out to start exploring Puget Sound.

The previous weekend had been a three day holiday weekend but the weather was lousy so we watched movies instead. Shawn took a day off from work, the following week, so we could head out to Blake Island, our initial destination for the weekend, on Friday and, hopefully secure a spot at the docks before the weekend crowd arrived.

I had spent quite a bit of time the week before getting the cabin secured for leaving the dock and it would have been a shame to waste all that effort by not going somewhere while everything was secured.

I guess we will have to make an effort to keep things secured during the summer so we can take off when we want to visit the many anchorages the sound has to offer.

We lucked out and got the last spot, in the Blake Island marina, that was long enough for our boat.

Blake Island is a Washington State Park with campgrounds, moorings and limited dock space. There are trails around and across the island and a small store. It is also where Tillicum Village is located which is a tourist attraction that offers performances of Pacific Northwest Indian dances and a baked salmon buffet lunch or dinner, depending on which event you sign up for. We skipped it this time because we figure we will have some guests before too long who will want to do it and we will go with them.

The island also has hot showers and power on the docks for visiting boats.

The only two ways to get to the island are by private boat or the Argossy Cruise line boats that transport tourists to the Tillicum Village. A lot of people take kayaks across the sound from West Seattle which is about 4 miles away. Friends who have done it says it takes about an hour.

We were feeling energetic so we took a hike around the Island. After about halfway around I started to think that the trails were designed by Escher since it seemed to be up hill the entire way.

We got some nice views of the south end of Bainbridge Island and the channels leading up to Bremmerton and several other interesting destinations for future mini-cruises.

The photo at the top of this blog post shows the map of the island trails that is located just above the ramp to the docks. It looks like a butchers chart to me with the various trails outlining the various cuts that can be secured from some lump of meat.

There is some wildlife on the island. We saw a few birds and quite a few racoons.

The ranger explained that the racoons on the island were tidal, as opposed to the usual nocturnal, nature of these critters. Their change in periods of activity is dictated by the ability to feed in the mud around the island when the tide is low. Because the racoons' periods of activity include daylight hours there is no time of day when it is safe to leave anything edible on the deck of the boat or when it is OK to leave the boat open when exploring on shore.

We found the island so pleasant and out berth at the dock so comfortable that we decided to spend a second night and just head home on Sunday afternoon. We had purchased a season pass for the boating facilities at the state parks so our moorage was covered. We paid $6 additional for power the second night (to make hot water for the dinner dishes)

We were pleased to learn that our new flat screen TV works fine off our inverter and does not draw enough power to cause us to avoid using it to watch movies.

We also had pretty good cell phone service on the island and were able to use the feature of our phones that lets us turn them wifi hot spots so we had good internet connections too.

There was not enough wind to do much sailing. There was a bit during our return trip on Sunday but it was on the nose and we just are not desperate enough to sail that we would bother tacking back to the marina.

I added an album to our galleries with some photos we took on the island.

Active Transport's Photos - Panama Canal Transit

Here is Equinox, a Island Packet Yacht belonging to Hank and Betsy Martin, that was to be our ride through the Panama canal. Notice all the fenders and old tires (wrapped in plastic garbage bags) that were set in place to protect the sides of the boat in the locks.  There are piles of tires in the marinas on both side of the canal.  I wonder if anyone has ever determined how many times a given tire transits the canal before its retired.   In the background is the bridge of the Americas that connects the panamerican highway across the cannal.
Every yacht transiting the canal is required to have an adviser on board.  This is our adviser Roben.  He turned out to be a very interesting man who has a full time job on the canal
Here we are approaching the first lock on the Pacific side of the canal.  There are two locks in a row at what is called the Miraflores locks.
Lots of fenders were used between the pilot boat (a work boat) and the yacht.  The pilot boat was up against the concrete wall of the lock and just took the abrasion in stride on its giant rub rails.  If the yacht had been tied up to the wall the damage might have been considerable.
this was our first view of the control building for the Miraflores locks.  This building is classic Panama Canal (aka Army Corps of Engineers) architecture.
Here is a close up, taken after we had locked up.  The sign on the building is of historical interest.
This is one of the "mules" that help the big ships through the locks.  The mules are locomotives that cost around $2.5 million each (the canal authority has around 100 of them).  They run on tracks and are driven by a rack and pinion system where a gear in the mule engages a rack that is located between the tracks.  This gives the mules a lot of traction when they are pulling a ship through the locks.  The mules provide about 30% of the energy needed to move the ship.  The rest comes from the ship
Here is a ship that was built to the Panamax specification.  At 106 feet wide the ship will have 2 feet on each side of it as it locks up or down.  93% of the worlds fleet meets the Panamax specification. and the Canal Authority is taking steps to deal with the post Panamax requirements.
Here is an historical anachronism.  The arrow on the end of this building indicates which lock a ship should enter and the time until t will be able to do so.  In this position the arrow indicates the ship will enter the left lock in 15 minutes.  At night these arrows are illuminated with neon lights.  They date from the days when radio communication was not reliable enough for adequate communication between the lock masters and the pilots
Our adviser required us to slow down (to reduce our wake) as we passed this explosives barge tied to the shore.  As we inched past the guyin the truck on shore was heaving boxes of what we assumed were explosives, into the barge with far more violence than our wake would have caused.  The explosives are being used in the widening and straightening of the canal so that it can accommodate more traffic and bigger ships.
This is a hillside in the Galliard cut that will not be there much longer.  The dots on the hillside are where they have inserted explosive charges into the hillside.
As we crossed Lake Gagun (largest man made lake in the world) we had to deal with thunderstorms that are shown in purple on Hank
This photo is a little out of sequence as its from the Miraflores locks.  It shows the curved shape of the leaves that make up the gates of the locks.  The locks are double to provide some insurance against an accident that might damage one set of locks and allow Lake Gatun to drain into the ocean.  An accident like that would put the canal out of commission for months wihile the water levels in the lake were allowed to build up again.  The gates dont close flat.  See the album on our Miraflores tour for more detail about how the gates work.
This is the control building for the Gatun locks on the Atlantic side of the canal.  On this side all three locks are together whereas on the pacific side there are two locks at Miraflores and another single lock about a mile away at Pedro Miguel.
