This boat has been sitting out on its trailer for about 7 years the deck appears sound and I haven't found any problems with the hull but while the mast is there about the only thing It does have is the hull , mast and trailer... even the rudder is missing but i got it next to free and I like projects . I can probably figure out a lot of what I need but pictures and diagrams will make it a 6-9 month project instead od 1 year or 2.
If you have the original spars and centerboard, you have most of the stuff that would be expensive to replace. You should be able to do your own rigging. Making a new rudder might be a challenge on this boat since you'll have to come up with a new shaft etc. It's little confusing in the drawing I'm looking at. It almost looks like it's supposed to fold up somehow. It might be helpful to study one on an existing boat if you can find one. No idea how many of these are still around.
Not a lot of help I'm afraid. I would be very interested in hearing about your progress. Best of luck with it.
