They haven't found a treatment that works yet,all I can suggest is a bigger boat shed.
Which brings up another question in my mind:
What do y'all do with all of your older boats? You've built, what, 10 boats or so Ron? Do you keep them all? Cut up/throw away early models that didn't work quite as well as later models? Do you find people interested in buying your older boats you were "learning" on, or were even your first boats top-rate and worthy of selling?
I don't have any indoor space, and my back yard is already getting crowded with a canoe and 3 kayaks.
I feel myself sliding down a slippery slope towards building a boat, like an ant falling down into an ant lion's den
I'm sure my skills will not produce the best boat ever seen on my first try, should I just plan on building one out of the cheapest plywood I can find just for the practice, then cut it up and build my real boat??
