You really think two up at 295lbs is the highest to be competitive?
I hope you are being a little sarcastic.
I would have to say just from the little racing that I have done, 265-330lbs to be really competitive. That's handling from about 5-15 knots. After 15, having a little extra weight couldn't hurt.
I'll be a little heavy myself with my dad on the boat, 345-355. I'm not to worried about it, this will be bonding time with the pop.
