Things to consider. And you should remember opinions from non family are like black water tanks. They are essential but frequently stink.
You might want to check and make sure the marina has extra slips and no waiting list. Sometimes if a marina is full, the boat's previous owner may keep the slip for her or his new boat. Or the marina may require you be on a waiting list as a new owner. However in this Texas economy, this is unlikely but worth a phone call to check. And BTW, with no trailer, what are the slip fees at the marina per year? If it takes you a year to repair the boat before you start enjoying moonlight cruising with your significant other, then remember the slip fees during repairs should factor into the cost. Plus, many marinas will charge another fee for shore storage while it is hauled out on top of slip fees. Further, many marinas because of insurance and EPA rules won't allow an owner to do fiberglass grinding, sanding, cutting or hull repairs them selves. They must hire marina staff or other bonded insured companies. That can easily exceed the cost of s boat in short order.
I would not be too afraid of condition, because sailing is sailing. But if appearance is important to you or your significant other, then, it is very important and these costs should be considered carefully, especially considering just how many really good sailboats are for sale in Texas now at bargain prices.
Again, glass work requires a haul out, labor, epa considerations, what do they charge for all that? That gets added to the cost. Can turn a dream into a nightmare in a hurry if you have to hire it all done.
Especially this is so when there are so many very good condition boats for sale in Texas so cheaply as now they are. And many have a trailer included.
a friend of mine who sells boats and accessories was lamenting the sail market. She said, "When gas goes back to $5 a gallon, sailboat prices will climb, but now it's not expected to be happening for at least a year or two." Two sides of the issue I guess.
Buy the boat, and have fun! Just keep both eyes fully open so there are no surprises.
