The Voyages of s/v Silverheels III
...a virtual ship's logbook, and some thoughtful (unabashed?) reflections on our sea-going experiences.
A New Opportunity, and Another Excuse!

01/30/2012, Mt Hartman Bay, Grenada

Last September I took a SCUBA certification course, and I loved it. Being under the water, feeling weightless and doing something that was just so cool. I am also very comfortable in the water, so it wasn't a tough transition for me to get into it.

Fast forward to January, 2012. Through our friends at "Scubatech" here in Grenada, I bought a new regulator and dive computer. This is the dive shop I took my course with, and have since become friends with. I was chatting with Jochen, who owns and operates the shop with his wife Sabine and Carsten, about the idea of going farther with my diving. I didn't mean just doing a Nitrox course and the Advanced course, but possibly as a Dive Master or Instructor.

Today we discussed it farther, and I have to admit, it looks darned good. Studying with them would also teach me many other skills not normally part of the course, like filling tanks and becoming proficient at fixing dive gear. The downside is that I would essentially have a full time job for a while, which would make boat work a little harder for me to do, and would leave much of it to Ken.

Ken and I discussed it, and he agreed that this would be a very good chance to increase my life skills... and potentially help the cruising kitty at some point. So now we have another reason to choose to stick around longer. I have 5 courses to take, and another 50-odd dives to get under my belt before I can be a Dive Master...

We've pretty much settled in for this winter to enjoy the relative coolness here in Grenada to get the pile of boat jobs lowered, and to get some of the extra "stuff" off the boat so we can find more breathing space. Now we have another reason to stick around. This may not be "cruising", per se, but it is still a darned good lifestyle. And man, am I going to get some GREAT diving in!

Lynn:
Getting advanced certification in diving is great. Congrats on considering to take the step. What certifying agency will you be under? One thing that you need to be aware of is that once you get a professional certification (and Divemaster is a professional certification) you will be payiing the certifying agency a professional fee every year, plus you will need liability insurance. The dive store might be good enough to pau those for you but it has to be in your name so you might want to check that out. I used to be a Master Scuba Diver Trainer for PADI and for my professional fee and insurance it would cost me about $1300 every year to maintain my status. With what I made teaching the courses it menat I taught four course to pay off the (overhead) fees. Only then would I start to put money into my own pocket.

Although I doesn't sound like it I am not trying to discourage you, merely food for thought so you'll do it with open eyes.

Interesting point above. I too would like to learn to scuba, and beyond the minimal 10 metre cert (I think) of the novice. Typical guy brain: there's math and gadgets involved and therefore it's interesting...and we haven't even gotten to the brightly coloured fish and dropped tools!

But if I HAD to teach in order to cover my bills as a professional teacher, it might be a different story. Would I want to pay to dive after I had not paid to learn? Only you can figure that one out.

On the other hand, if that's your biggest dilemma today, that's a pretty slack day!

or try a few coloured cable ties at each marking point. Hi from bob and jane. We are back in Bahamas (year 4 - can it be that long?)
Thinking of you guys as we are at Black Point.
Sounds like you're never coming back this way, but you're welcome if you do....

The New Cruisers' Duct Tape?
Lynn
01/28/2012, Mt Hartman Bay, Grenada

What I am going to say may be heresy to some. I admit it, and I am ready for the responses and the hoots of derision. However, I am no longer a complete believer. I no longer think that duct tape is the greatest thing since sliced bread on a cruising boat. There, I said it.

So what has drawn me away from the teachings of Red Green and many other wise people? What has made me open to ridicule and being pointed at in the street by passer-bys? "Rescue Tape" has made me a convert to its' powers.

"Rescue Tape" is a silicone-based self-almagamating tape. It's nice to have something that doesn't rely on an adhesive for its' holding power. After a tour of duty hanging out in the foc's'l of our boat, duct tape's adhesive can get a little uncooperative, often splitting its' attention between both sides of the tape. NOT helpful when you need it to to be somewhere of your choosing. The self-adhesive qualities of Rescue Tape means that the "stick factor" is impervious to temperature and the vagarities of humidity. Yes, it does require the tape to be wrapped around something, but that is often the purpose given to duct tape, too.

Okay, adhesiveness alone isn't enough for me to allow myself to be publicly ridiculed. How about the fact that this stuff is rated to temperatures up to 500 deg F? Holy Hades, Batman! You can actually put this stuff on a leak on an exhaust hose and have confidence that it won't be a melted puddle of gunk in the engine compartment in a matter of minutes.

This stuff is also rated to 8,000 volts.... what does this mean to a cruiser? It means that this tape can be used to insulate any connection on the boat. We don't use it alone, most of the time, but it has its' uses. For those with an SSB antenna, it can be used as insulation for the GTO cable to antenna connection. We've also used it as added insulation and strain relief on microphone cables, since ICOM doesn't seem capable of making microphones with good strain relief on their own. We cheated yesterday and used it to insulate a splice in one of our lamps (we took the dimmer out of the picture as it was not working). If you don't trust the connectors alone, a bit of this stuff will do the trick. Try that with duct tape; actually, please don't. It also doesn't create a mess if you need to remove it to get at something... that's the no adhesive thing again. We now use it in conjunction with coax-seal to waterproof our outdoor electrical and radio connections... it isn't anywhere near as messy as coax-seal to work with.

The next selling point for me is that it is also rated to 950 psi. Ah, so it can be used for engine leaks in other places, too! And because it is impervious to most chemicals, it won't degrade. Oh yeah, it is also UV resistant, too. Try leaving duct tape in the sun for a while. It's also waterproof, not that this is much of a surprise.

We were first introduced to this stuff when our buddy David had an emergency on his boat. The seal on his dripless shaft (good lord, that sounds rude) split, and he was taking on water at an alarming rate... literally; his alarm on the bilge pump went off. Someone else rushed over with this Rescue Tape and bound things together well enough for them to motor the boat around to the next bay and get hauled out.

We are going to try a couple of test strips on our anchor rode to see if it will work as an indicator of how much chain we have out. It will be easier to work with than paint, and it may not come off as easily. We bought a number of rolls at the Toronto Boat Show (cheap!) in different colours, so we will be able to use our familiar colour pattern on the chain as we have since the start.

I don't see people making quotes about this tape, like the many comments about duct tape. I don't see Red Green (who in real life IS a boater) changing his show for this stuff, but I do see how it is one more thing that can prove very useful on a sailing boat. Too bad it can't make coffee...

We also discovered Rescue Tape at the Toronto Boat Show a few of years ago. Best money ever spent. I've used it to seal a leak on my vacuum cleaner hose at home, and to close up the gap between the mast and mast boot, to keep rainwater from running down the mast. Last year we used some to repair an inconvenient electrical problem on a charter boat in St. Martin. Don't leave home without it!

I used it on a leak I had on an oil hose on my engine and the oil blew right past it. Oil seaped out where the tape ended even thought I extended the tape 5+ inches on either side of the small hole. I finally replaced the hose when I got to port.
Not a big favorite of mine. I've still got several rolls but hesitate to use them.

While the merits of Rescue Tape or any self-adhering silicon tape are many, I find it's too expensive for marking anchor chain or rode.

You might wish to consider Liquid Whipping for that job. It's a tip I read some time ago that I will be trying in the spring on my new rode. Word is it lasts a lot longer than paint, because it's really a rubbery plastic skin.
