For 12 hour trips I've been on, New Buc cruises about 25kts for a roughly 4 hours, so whatever that distance works out to be with the occassional weaving/tacking so we don't get beat up on waves.How far you go out on a 12hr trip? The Double eagle has been running 12 hr trips that cost $175 per person and they go out about 35 miles max. They are now running some 12 hr nite trips from 6PM to 6AM for mangrove snapper. They don't burn much fuel and seem to carry around 19 to 28 people. Once red snapper open they will run out to 60 miles offshore. Gags are closed for most of the year over here since they are all but gone. But red grouper is open, but they are in bad shape and i am sure more lock downs on them are coming.
Expect shoulder to shoulder with 100 people during red snapper season.
Still cheaper and worth the occasional line crossing than buying, storing, towing and maintaining my own boat capable of going that far.
