It all started when I removed a screw from the transom and water ran out. I was initially in the process of vacuum laminating in a new transom core when I decided I really liked the cockpit without the splashwell, and things just got out of hand from there. Since I didn't want to see the look on my wife's face when the back end of the boat fell off in deep water, I read a bunch of books, communed with folks at boatdesign.net, consulted with a naval architect
and a marine surveyor, looked at each and every post and pic that Oldgrowth posted regarding his project, and am currently winging it on my own...
Having lived in the Annapolis area for a while I always liked those long cockpit oyster boats with the small forward cabin. This boat will have a bit of that look to it.
I'm going to end up with a transom, splashwell, and storage compartments that are similar to the current 22-foot C-Dory offerings. Luckily, a friend of mine has a 2007 22-Angler and he lets me come by and measure and consider on a regular basis. I'm pretty much sold on a coupla 24-gallon saddle tanks at this point and the new gunwales may be around 10-inches wide to accomodate them and storage lockers below. I like the idea of having an area below the splashwell to throw big items and keep 'em out of the way. The gunwale at the steps is likely to remain at the six-inch width. The new profile aft of the cabin will be much more of a straight line than the Classic, but that's what I get for adding ten inches in width to the transom and moving it back four feet; I'll get as much curve as I can. The wider transom will accommodate a remotely-operated kicker mounted to port of the Honda 90.
To starboard will be the battery locker; to port will be a propane locker. One of the current conundrums is how to keep the batteries (2 starting and 2 6V house) low and still have easy access to them. That's gonna be a bit of weight with those batteries up that high. Maybe I'm over-considering the issue, but I'm prone to that...
The gunwales have been removed and the new sheer line profile will be pretty much in keeping with the upsweeping character of the Classic; the current models are fairly flat. Once I'm finished sanding the interior of the cockpit hull sides, I'll cut the lapstrake sections apart and remove the one-inch horizontal bits; the lowest section will remain attached at the chine. I'm impressed at the flexibility of the quarter-inch glass at the top edge while it's still attached. Once the frames are built the old glass will be repaired before I begin the new section; doing a 12:1 scarph joint for those repairs and keeping the one-inch lapstrake look that will eventially taper out at the transom. The old and new boat will be joined using a 24:1 scarph at the suggestion of the naval architect I consulted. The boys at Gougeon Bros. support this approach.
The new sole and transom will be plywood; I'm not sure if I'm going to make it from scratch or not; might just get some good thin A/C and laminate that up. The original sole core was - I believe - fir, but surprisingly full of voids; pretty much construction-grade stuff. The new ply you see in the pics at this point is just mockup stuff. The sole core will be half-lapped over the old by at least a foot.
I've got a lot of work to do before I flip the boat over to begin glassing. There is very limited space in my shop to work so I got the idea of making a couple of eight-foot wheels that fit the profile of the boat - one just aft of the cabin and one just ahead - that would turn on heavy rollers on the floor. A Wooden Boat magazine subscriber told me he'd seen just that concept a few issues ago. Here's what they did:
Mine'll be beefier as I'll also have to raise the upside down bow to lower the transom to a reasonable working height.
I've been delving into the C-Brats photo albums for the best ideas to incorporate into my boat - and there are many. This project has been in the learning/design phase for over a year and luckily, the design is still flexible.
It keeps me off the streets during the day and up at night...
