I am a StarCraft guy. Superfisherman 190. I have pals that have Star Crafts as well. 1 is a 21 foot centre council Heritage, another has an Islander cuddy and 1 has a restored this year early or mid 80's 19 footer, we don't know the model. All are good solid boats from the 90's. Each and everyone has it's advantages and ride differently. Mine has a deeper V than the 21 foot Heritage but the Heritage will handle the same water conditions as mine which looks to have a deeper V design. You seem to be hung up on this "deepV" hull design. I have been in 18 foot glass boats that are not what would be considered a deep V feel to me more of a solid ride than the 21 foot Star Craft in similar conditions because it is more stable and has far less bumps and bounces because of the glass construction and sheer weight increase. I don't really understand why a seller wouldn't post or know the year of his boat, no paper work? That is sort of important.
This past winter 4 of us took a early to mid 80's 19' StarCraft down to it's bare bones and splashed it in late May. Someone had started the restoration and gave up. The boat was bought for $900.00, no trailer or engine. We didn't work on it everyday but put in at least 20 to 30 man hours per week, I want to under estimate, from November to May. A rough calculation says it all added up to about 500 to 700 man hours, probably more. Some weeks I didn't see the boat, I was the detail guy, cleaning all and everything that came off of it, railings, swim ladder,carpeting, seats, paint prep, repainted the new to the boat used outboard, things of that nature. I wasn't there to see all of the hull repairs but I do know they bought 2 boxes of rivets with 500 and each box and there was 1/3 of a box left over. That was extensive. Plus there were a few spots where small sections of the hull had to be veneered with aluminum where there were cracks, mostly where the stringers met the side of the hull. You won't know what is really needed until the floor and foam is all removed. That task was not fun. That sprayed in foam had to be removed with a butter knife in the hard to get to spots.
I won't go into a complete restoration history but the point I want to make is you don't know what you have until you start surgery. It is important to stress that if it looks good it hopefully is good. If it looks like a basket case you are into a full out resto. And time is not your enemy the budget is. After all the hull repair the boat leaks, a small leak but it leaks. Most likely the transom that looked solid as a rock. That is one reason I didn't enter it in the Star Craft Splash of the Year thread. The main reason it wasn't my boat and we/he didn't make any notes for timeline and materials used and he cheaped out on some things that just weren't done right because of a growing and it grew quickly budget. All in he has $14,000.00 CDN. I bet he could have bought a very nice newer boat for that, no I don't think I know. It really is more than that because I know I didn't charge him a dime. I just got 1/2 of a nice size Deer for my labour.
I have to ask and I'm sorry if I missed it, what conditions do you intend on boating in? We are on Lake Erie and there are times no pleasure boat is big enough. I will boat in 1 meter or less waves only if I have to. Which means when it starts kicking up unexpectedly I'm heading back to the Marina. Plus I find no fun trying to fish bobbing up and down like a cork. The conditions will dictate the design, construction, power and size of the boat you are looking for. Trailering is an important issue you mention. We can get the Islander a pal has in and out of the water in minutes when everyone does their job. The 24 foot Owens Cuddy is another matter. When it's time to crank the last 6" onto the mast everyone disappears. I wish he would get an electric winch. Plus pulling it with the 1/2 ton 4X4 you know there is a boat behind you. With the same truck you can't tell the 21 foot Star Craft is there without looking in the mirror. Oh my look at the time, my index fingers are sore too. Good luck in your search. I wish you luck. Finding an old boat is the easy part and it took me 3 years of looking every week. I found a few I wanted to buy but didn't because there was not a paper trail and I didn't let the boat or price blind me, that can happen only for the owner to have to jump through, over and under many hoops to make it legal, not worth it.
