Why not?
I mean these are not insignificant purchases. They represent a sizeable investment. Wouldn't you test drive a car, or even a number of cars before deciding on if it is the right choice for you? This is especially true if the boats you are looking at are used boats, but even brand new, you need to know if you are going to spend a considerable amount of money on something that you will be happy with. I don't really see it as a problem if the option of a test drive is available.
All that said, we have a Bass Tracker Pro Team 175 TF with just a 75 hp Optimax and just flat out love it. It jumps up on plane in seconds, handles great, although I wouldn't keep up planing speed over 2 foot wakes, 1 foot it handles quite well. Does it slam hard sometimes... yeah, it does. But it handles it like a champ and remains quite handlable. Also, when there are large wakes over a foot, I definately would slow to no wake speed and take it easy, but I'm not an extremely experienced bass boat driver either. Also, I've found that over 1 foot wakes it helps to trim up just a tad (doesn't take a lot--just a tap or two) for a smoother ride. Now consistent waves, I slow down, but again, it is a lot because I don't feel experienced enough to plane over consistent 1 foot chop or waves. I have been in a glass bass boat, but it was years ago and I can't really remember enough to compare, my choice of the metal tracker now was partly price consideration, and partly space consideration (very narrow, short garage).
