It's been slow going as this is our rainy season, but we have removed all the broken pieces and have begun reinforcing the hull deck joint. One of our volunteers is planning to screw a thick piece of line all the way around to act as a bumper, as this will be a trainer boat.
The original had plastic rub-rail, for the same purpose. Sounds like a plan.
It appears the hull deck joint is stapled together? Do you guys have this?
Can't say. The actual joint is hidden under the rub-rail on the outside and from the inside, some previous owner applied a layer of glass for extra strength. I'd go for the glass (at least in the foredeck area).
We still have no clue what year this boat is, any ideas would be great.
Look in the thread on DS1 design changes. There's a spreadsheet that list boats with known numbers and years and the small design changes from model year to model year. That might help you pinpoint it. Alternatively, take more detail pictures of anything that shows small design details. The logos, the chain plates, where the jib sheet fairleads might have attached, the CB trunk details, transom details, including from the rear, etc. That might help the sleuths here. Many of your photos show large views with the interesting detail features hidden or cut off.
Two features that I don't recognize are the CB uphaul on top of the trunk - that looks more like a DS2, unless that design was used some years. Also the dual drain in the back and the very pronounced center rib along the rear of the cockpit floor.
Also, does anyone have a pattern for the seat? I have been unable to find actual measurements to go on. Ours is completely gone.
What you are referring to is the "thwart" that connects the bench with the CB trunk. It's just flat board. The width and depth are kind of indicated by the notches in the seat and the length is given by the dimension between bench and CB trunk. When you measure that try to have the hull supported in a way that it doesn't splay open or is being pushed shut. I suspect the yard of having cut mine based on what fit, rather than fitting a fixed, pre-measured size.
There should be some L brackets to support the thwarts on the CB trunk wall. If yours are missing, any home grown replacement will do.
Also, Does anyone have any close up photos of the original arrangement of the carlins that support the side decks?
No photos, I think (I'll look). The carlins are something like 1x1 that run directly along the "lip" of the side decks and transom. They were lightly glassed. I would epoxy seal the replacements (all 6(!) sides plus any and all holes need sealing) and glue them to the decks with epoxy, glass isn't going to do much.
In addition, there are plywood "knees" (essentially triangular pieces) between hull and side deck. Glued to the hull. Every 18 to 24", I think. I would, again, seal these with epoxy. Whether you should saw the long side in a hollow curve is up to taste.
