Weather permitting, I wouldn't think twice about taking a Bayliner Trophy offshore. Unlike a gude I can take my time coming in, if it takes 90 minutes instead of 45 big deal. I took my 17' Malibu Tyee 15 miles off Bamfield a few times times, many times 7-12 miles, and 12 miles out of Kyukot a few times.
I know it can get hairy of WCVI but I've seen more decent days than crappy ones in the summer. The idea that you need a big boat to fish out there is a little over played IMO.
