Boat Name and Logo

The port outboard hull side received a coat of arctic white with a little dark blue pigment in it. I’m not sure how much difference it will make compared to the cabins and deck which are untinted. The crease in the hull at the sheer automatically creates a different shade of color between the cabin [...]

Attacking the Topsides

It was possible to make a time lapse video with a couple of problems. To get the mast and crane in the pictures, I shot in portrait mode. Plus I was using Canon’s “L” size for the photos. The video application is looking for landscape mode and a smaller sized frame. So, the video comes out [...]

furball Catamaran Dinghy

Richard and Gill launched their little catamaran dinghy that Richard built from plans. They named it “furball”, as that which is spat out by the larger cat-amaran. Here is a link to more photos of it:

Things are beginning to heat up in Bermuda with the new America’s Cup catamarans practicing ahead of next months round robin sail off, followed by the Louis Vuitton Cup, and finally the 35th America’s Cup between the Louis Vuitton winner and Team Oracle USA. If you search myislandhomeBDA at Youtube, you’ll find plenty of footage of all the competitors zooming around on foils. One video was an explanation of foil attitude strategy and the reason for the boats looking a bit down at the bow while foiling downwind. The fellow explaining it said something like, “we want to keep the boat level foiling upwind, usually about 27 knots, so when we bear off downwind at around 40 knots, we have to reduce the angle of attack on the foils by pitching the boat down at the bow.”
.
My boat lettering came in, faster than expected, and I’m excited to see what it looks like on the finished paint job. So, I will be busy the next few days on that.
.
For some reason I had been coughing a lot and I thought it was due to paint fumes or sanding dust, but someone said something about fires burning in the Okefenokee swamp not far to the West of us. The sunset was spectacularly blood red, so I took a picture.

The port outboard hull side received a coat of arctic white with a little dark blue pigment in it. I’m not sure how much difference it will make compared to the cabins and deck which are untinted. The crease in the hull at the sheer automatically creates a different shade of color between the cabin sides and the hull sides.
.
I applied most of the paint using a 3/16“ nap roller from Lowes. This left a surface with tiny bubbles which I hope will smooth out. Maybe not.
.
3 cups of epoxy was enough to prime the whole hull side, but it began to go off when I got to the stern and made a rough finish there that had to be sanded smooth before painting. Next time I will mix up two batches of 1 1/2 cups, one at a time. The paint is mixed in a small batch with about 5 1/2 oz. of total mix including 1/2 oz hardener, 1 oz reducer, and 4 oz. of paint. Mixing it this way for an entire hull side would be tedious, but I had to use my mixing measurers, ones that I know won’t dissolve in this paint, which attacks most plastics. A paper cup looses its bottom with it. So, I mixed a double batch of paint, or about 11 oz. which is a bout a cup and a half. It did not cover as well as the epoxy and I needed about 3 double batches to do the hull side.
.
It is reassuring that this hull side was the worst of them all and needed a lot of repair and fairing. Getting it to this point, only needed another coat of paint (I hope), gives me the feeling that this project does have an ending and it’s not as far away as I thought.
.
The internet DIY boat lettering people, http://doityourselflettering.com/, had sent me a proof with Kaimu’s boatname, hailing port, and the Wharram logo. I thought having the hailing port in gold would be better, but after looking at the proof decided to stay with black lettering. I had them remove the comma between Norwalk and CT and ordered the lettering. The logo goes on the bow, name and hailing port on the stern.

Attacking the Topsides

It was possible to make a time lapse video with a couple of problems. To get the mast and crane in the pictures, I shot in portrait mode. Plus I was using Canon’s “L” size for the photos. The video application is looking for landscape mode and a smaller sized frame. So, the video comes out lying on its side and oversized for the computer screen. In order to make a proper video I would have to resize all the photos and rotate them. Probably have to rotate and crop, then resize.
.
There was actual work going on through all this launching and playing around in Richard’s dinghy. He let me ferry crew back to the dock after the catamaran was anchored in the North River (Marsh). The dinghy is so cute, but it is small with not too much freeboard. It looks like it will be OK for two and in harbor use, no choppy bay crossings. It is very maneuverable and moves easily through the water. He hints that he might make an improved model. As it sits now in the water, he will have a lot of sailors asking him what company makes it.
.
Also, one of the spectators at his big catamaran launching said they thought Fountaine-Pajot had stopped making the Antigua model. They had, long ago. This boat is over 20 years old, but the spectator thought it was brand new. It is a showpiece.
.
I was starting work on Kaimu’s topsides and experimented with using a paint pad to apply the arctic white acrylic urethane. It works, but is slow. Next I will use phenolic 1/4“ nap rollers. The quality of the finish might suffer a bit. It will allow larger batches of paint and faster work.
.
Instead of working with 20-30 sq ft patches of hull, I can mix a quart batch of paint at a time and roll it on before it goes off. I should be able to coat about 2/3 of a hull side at once. Thus, I began expanding the preparation to an entire hull side at a time. This works out even as the weather heats up, because there is always at least one hull side available in the shade. My plan was to get the deck and cabin top work over with before the really hot weather arrived. The forecast is now for up in the 90‘s the next few days.
.
We had a celebration at the gas station restaurant and had a larger crowd from the boatyard than usual. As we sat around the table I noticed there was only one captain there who had a monohull, and he was looking for a catamaran. I pointed to myself and said, “catamaran”, then went around the table, “catamaran”, “catamaran”, “catamaran”, “catamaran”, “catamaran”, “catamaran”, and finally, to the odd man out, “monohull”. He responded with the nautical equivalent of “Oh shucks”.
.
I found the best tool for attacking the surface of the Wharram hull is the belt sander. I was using 40 grit belts from Lowes. The bite of these belts is aggressive and the belt sander gets pulled along. Aiming it up the hull and leaning on it just a bit causes it to go along like a self riding lawnmower. Otherwise it would be a very bulky tool to use.
.
After doing the topsides from the waterline up to the sheerline, I used the angle grinder with a 36 grit flap disk to feather out any remaining divots in the old paint. If there was any question about the old paint’s condition, crazing, cracks, flakes, it was sanded off. The result was a dull flat surface with little smooth craters where a pit or crack was sanded out.
.
The port outboard hullside was the one in worst condition. There was a 20 sq ft patch of missing sheathing and a bad section of sheer stringer/rub rail. The sheathing problem was mostly below the waterline, so a narrow repair was made on the part that would be painted along with the topsides. The edges of the fiberglass repair were feathered out into the hull’s surface.
.
The spots that would need filler were first primed with unthickened epoxy. Then a mix of colloidal silica/phenolic microballoons (50/50) was troweled on with a homemade plastic disc that looked like a half moon. I cut it out of old kitty litter pails and made the curved part match the curvature of my mixing bowls. This way the curved part could scoop out all the available fairing mixture and the straight part could smooth it perfectly flat. This hull side, port outboard, was the one with the most repair work, yet I was done with the fairing mix by 3 in the afternoon.
.
In one of the photos taken during Time and Tides launch, Rocky, the boatyard owner and manager, is checking the progress with Kaimu in the background. Kaimu’s hull is dirty with old paint and mildew. The next day I tried a cleaner called “LA’s Awesome” because one of the yardbirds said it removed mildew like magic. I wet down the hull, then sprayed the cleaner all over, then quickly scrubbed with a soft brush on a stick. The mildew came off like magic. I then did all the rest of the boat prior to sanding and fairing. I will post an “after” picture next time.

I’m going to try to make a time lapse video, but if you go to the end of the album and select that picture (it’s actually near the beginning of the shoot), you can backspace through the album just like a time lapse.
