Triton FS 190 handling big water??

Hello all, I have never posted in any forum before. I am hoping to get some insight on how the Triton FS 190 handles some decent sized waves (3-4 foot white caps). I fish up on Rainy Lake on the US/Canada Border and it can get rough sometimes. I am looking at pulling the trigger on a 2004 model. My only concern is how it handles the waves. Normally I won't go out in the windiest of days, but I can't make the the weather on tournament days. I am hoping to get more insight on this particular boat rather than how much better a 621 or something would handle. Thanks for your time! I will appreciate any comments, positive or negative.
