WELL...I am ready to get said rivets set and now have just acquired a 21ft. Duckworth welded boat!! So beleive i am going to put my 1983 Starcraft V220 supermariner up for Sale..now I know that my boat is a very rare model and this one is in pretty good rebuildable shape..Transom is good ,no big amount of corrosion..I stripped out all foam,inspected everything and it appears that just rivets that we're sandwiched between boat and trailer bunks heads were flaky...those rivets are tight just heads compromised...drilled a few out..pretty easy project ..So saying all that what would be a decent price to put on that boat to sell? Thanks Crabeye
