Don't understand the question, but I've delivered, crewed, or fished on yachts up to 75'. The heaviest was a small tuna seiner converted into a mothership for a sportfisher. I think that's what you are asking.
Probably a different ticket for what you do. I mated a lot on head boats and was talking about a paying passenger ticket.
Just took in your 'about page.' Dad's OK!
My biggest tuna was a 350# big eye, stand up fishing.
You ain't seen chaos till you mate on a 65' with 30 passengers on one side and the yellow fin bite is on! At night!
Granted, most of 'em were in the 75-100# class, but it's a trip!
