I think you may be attempting to extrapolate too much only from the length of the boat. Equipment
, skill, and planning all factor into to being able to do something like "cross oceans frequently". People do cross with cats 35 ft. as indicated correctly by your research
. So why can't you?
Minimum boat for California
is 8 feet 9 inches but it was a mono hull
. Skill and planning add a lot to the length of the boat. Your ability to handle the boat makes many boats minimal. If you expect to carry a lot of dive gear
you'll need to consider the weight and space requirements. If you use those numbers to compute what it's going to require to float all this stuff the minimal boat is not big enough. The minimal boat is really unimportant. If you can't afford a 50 ft boat then it would appear it is impossible to cross in a 50 ft boat since you won't be able to get one.
How much stuff are you expecting to haul around? If you are going to do "frequent crossings" I think the term frequent might require some additional details. Going half way around the world frequently from Bonaire
leads me to conclude you may be based in the worst possible location on the planet as amazing as that sounds. Relocation to Thailand
might improve the scenario a lot at least from a boat shopping
perspective. Cutting 10,000 miles off the trip might save on the wear and tear too. Gets the costs down a lot as well. I'm not well aware of recreational boats that can do half way around the world and back on a frequent basis.
