Cabin Boy Refit
After valiantly following in the Blue Moons wake for 2000 miles... in turns taxi, cargo ship, and conversational ice breaker... on three occasions -- one critical -- the little boat that carried my extra anchor to deep water, allowing me to warp the Blue Moon out of a nasty situation... for all these reasons and more, Cabin Boy will always be more friend than boat.
When Helena and I pulled Cabin Boy from Huntington Harbor on the day before Thanksgiving, 2010, he had a quarter inch of green slime on his bottom, rusted rowlocks, and bare wood that should have proved to me, once and for all, that linseed oil is NOT a practical finish for wooden boats. (Of course, I needed more convincing, but thats another story.)
He was also 20 lb. overweight from the salt water hed absorbed on the trek from Jacksonville, FL -- the last time hed had a good dry out.
After car-topping him home, Id scrubbed the gunk off his bottom and carried him into the basement where hes been resting on saw horses for over a year and a half, while I refitted the Blue Moon, which was in more urgent need of scraping, painting, and re-rigging.
However, with the Blue Moon now in pretty good shape, it is definitely time to give Cabin Boy the TLC he so richly deserves. Helena and I move him to my workbench a few days ago, where I could put some light on him, and finally take a good look at the scars left on him by King Neptune.

First, the good news. As Im sure I mentioned back in the day, the John Atkin designed Cabin Boy has never leaked a drop. The combination of white oak, quality marine plywood, and glued lapstrake construction resulted in a mighty strong and water-tight boat. I carefully inspected all his seams under the light, and could not find a glue joint that looked worse for wear. And that is despite the fact that I did not understand the need to use fillers with epoxy. All the joints on Cabin Boy are straight, un-thickened epoxy. Either Ive been very lucky, or I did a darn good job on making those joints fit tight. (Im betting on luck!)
Cabin Boys transom is a single mahogany board. You will recall I didnt have time to varnish it, so I tried using linseed oil -- a finish some boat builders swear by, but I swear at.
I did try to keep up with it, re-applying the oil whenever I could, but it just wasnt good enough. I probably should have painted it a long time ago, but never had the heart. The plan is to give it a good sanding and many coats of the varnish it has been waiting for.
The seats were another rush job that just barely did the job. They were cut from some leftover marine plywood. Left unfinished, except for a few linseed oil treatments, theyve weathered but are still structurally sound with no de-laminations, despite sun, rain, and general mistreatment. Another testament to quality marine ply.
The seats were always a stop-gap measure; they will be pulled out and replaced by comfy sternsheets and a fore-and-aft rowing seat that Ill no doubt discuss in detail in a later post.

| These lousy plywood seats gotta go! And the galvanized rowlocks, too! |

| Slightly cupped keelson needs to be fastened to the bottom. |
Another oddity is a mysterious gap between the sternpost and the skeg. I have looked at this, and looked at it, and cannot figure out how it got there. Im sure it wasnt there on Cabin Boys launch day, but I just cant see how the gap could have opened, unless the skeg expanded in width somehow by 1/4".
Very, very mysterious, but easily fixable.
Another unfinished project were the gunnels. I never did get around to fitting the inwales or outwales. The poor unvarnished knees with the notches cut out but unused were constant reminders to me that everything takes longer than you think -- especially in boatbuilding.
Cabin Boy is so stiff, he doesnt really need gunnels, but I want to install them anyway, just for looks. But should I replace these knees or do they just need a good sanding? Ill soon find out.
So thats an outline of the project. The first thing I wanted to do was to remove everything that could be removed for sanding and varnishing, but before I removed the seats, I wanted to measure and cut those inwales.
One reason I didnt finish them 2 years ago was they proved more difficult to fit than I expected. Cabin Boys sheer twists and curves in a complex shape and I could not figure out how to fit the inwales properly. I gave it a few hours, but had to quit in disgust and head down to Steinhatchee.
My new bronze rowlocks will fit into a small spacer block that fits between the sheerstrake and inwale. I made a block of the correct size, and used it to mark the location and depth of notches in the frames. These notches are a bit of a kluge, I think, but will put the inwale at the correct angle to and distance from the sheer strake.
And here is a bit of white oak bent into the shape of the inwales. With the notches cut correctly, it bends into the correct shape with a bit of convincing from a bevy of clamps. Hes looking better already!
But that was just a dry fit, of course. At the moment, Im removing bits, not adding them! Only the hull seams are glued, so with a bit of quick work with a screwdriver, the seats, knees and rusted rowlocks were soon out of the boat.
It sure would be easier to paint (and bail!) Cabin Boy without that darn keelson... should I remove it? What do you think?
Besides sanding and painting, there are some edges that got severely chaffed by ropes, chains... who knows? There were a couple nights there where Cabin Boy had to take one for the team. He did so without complaining (and without sinking!), and the damage is nothing that cant be fixed up with a bit of sandpaper and paint.
So thats it. Im hoping to have Cabin Boy spruced up for a fall cruise, so theres going to be a lot of juggling going on here. Watch out for falling bowling pins!
Very, very mysterious, but easily fixable.
