Re: 1977 Starcraft Cabin Cruiser 25'
You're getting some good points from knowledgeable folks. While it's probable that, in the end, none of us can tell you what you should do, I can assure you that the comments are aimed at helping you to have a pleasurable experience.
I have been boating all my adult life (yeah, it's a while) on boats no larger than 18'. It's pretty easy to handle a boat that size, even for one person. You won't need a heavy tow vehicle, easy to tow and launch/retrieve. Last year I moved up to 21' that is longer, wider and heavier than I was used to. Man...what a difference...everything became instantly more difficult and more expensive (some will say that costs rise exponentially with size).
To begin your boating life in a 25', 35 yo boat seems, well, ill advised. For one, you will find that the cuddy will become a large storage closet, not sleeping quarters...they are just a sauna most of the time. I'll also suggest to you that, if the first ride or two doesn't go well, you're gonna lose your mate and crew for the bad experience and you'll be getting constant resistance to future adventures.
Probably best to invest in a smaller, open-style boat for day cruising and fishing. Yeah, you'll soon get "two-foot-itis" but you'll also likely have the rest of the family wanting it too. Good Luck.
