St,Marteen shipyard can handle that beam, and more, they use 2 ways, a heavy crane and sea lift
with air bunk suport, but,, you are far way from town and close to the airport
, nothing else around, they charge extra if you do your own work or if you live onboard , the place is clean and with lots of people working around, FG, welders , etc..
Polypat in the french side also can handle wide beams , by crane, good people around not so clean like st marteen shipyard , security
is a joke.
Time out boatyard in front of polypat, lift
by crane to, not sure the max beam, the crane is very old, check insurance
, more dirty than polypat but new showers and toilets in the boatyard, excelent people around, do it yourself , no extra fee, or let others do the job, security
is a double joke.
JMC is the 3 one, forget the idea, is kinda a prison, very dusty, and security here is a real problem.
Geminga boatyard can take a catana
47 , a l440, and i see a swicht 51 in the air to, nice people around , one of the best Fglass profesionals in the whole caribbean
, welder, woodwork, volvo
shop, etc.. very dirty and security is not ideal.
Boby`s marina in the ducht side, the new one can take any beam, expensive, clean, security, and close to town with island water
world and budget
marine close by. Best record
Hope you get a idea of st marteen, good luck.
