Hey mate,
I've been on the water for a couple of years now. Personally there was no way I could start on a fibreglass boat, especially that size. You will learn a lot of things about boating as you go. I still learn to this day as different water ways offer different situations.
I started off with a 4.1 Bermuda aluminium. Light, can manouever it easy in and out of the water.
I've already put a dent in it, and that was my friends fault, but still you learn from your mistakes and you don't want to do that on a $35k boat.
Just other things to think about:
Have you reversed a trailer before?
Launched/retrieved a boat?
Current might be going one way, wind might be going another, and when you get to the ramp and your bringing your boat in, you might not be able to get it dead centre on the trailer especially at first with lack of experience. A small aluminium boat will be easier in that situation. Also if you run aground, you have a better chance pushing a alloy boat than a fibreglass one.
With that stacer boat, I would be checking the Hull, make sure there are no dings or slight cracks underneath. GO over the whole boat.
Check the trailer, check for rust, check the leave springs. Look at the condition of the winch. Make sure all electrics are working (lights) - spare wheel?
Motor, 80 hours isn't much, mine has 80 hours and my motor looks brand new on the inside, have a look. See if any bolts have been taken off, if so, the head has been removed for some reason. Check the spark plugs, see what kind of condition they are in. Fuel lines.
Start it up when its cold, make sure he hasn't fired it up before.
Just a few things to look at.
