Interesting responses...thought this was almost a rhetorical question.
But it appears there's no consensus on what counts or doesn't count. And how it weight capacity is enforced.
Maybe I'll reachout to my dealer rep out of curiousity.
My main concern is just safety. I've only had one 750lb sac in the rear port locker of the X55 as a test run, and that created a pretty serious list. I'm considering adding a second 750 under the port side seat (that seams to be the recommendation for optimal surf wave) and honestly, a bit nervous of the idea. But I know smaller size boats do it all the time. Probably just have to get used to it.
