Weight of a Formosa 51'?

My U.S. Fed Doc says my 1979 Formosa aft cockpit 51', is 33 tons net, and 37 gross. My new dock neighbor here in Cartagena, who has an identical (and very very beautiful) 1978 says his reads 20 tons. I am trying to haul out soon and my weight will determine my options (and if she's really 37 tons, then there are no options at all!!)
I've had her for 13 years so you'd think I'd know but now I'm heartily confused.
Anyone know the truth (or close to it?) I'd really appreciate it!!

Re: Weight of a Formosa 51'?

The tonnage on the documentation is a measure of cargo volume, so not useful for haul out weight. Search for Simplified Measurement Tonnage Guide USCG

The difference is not worth worrying about for lift out.

My sailboat has a displacement (weight) quoted by manufacturer of 7.2 tons,
a gross tonnage of 13.65 tons, and a register tonnage of 13.65 tons.

The 13.65 tons is based on a cargo capacity of 38.63 cubic meters.
But I still have problems storing supplies for two people for 1 month

This is an anachronistic measurement, nonsensical for leisure craft, but it is used throughout the world.

The tonnage has nothing to do with weight. A tun is an old name for a standard barrel (252 imperial gallons), so it is a measure of how many barrels you can theoretically carry in your hold.

33 tons means you should be able to fit 8,316 gallons of rum on board.

Re: Weight of a Formosa 51'?

Yes I'm hoping there's someone who has actually knowledge (previous haulout?) of actual weight in lbs. In Los Angeles she was hauled multiple times (as well as in San Blas, Mexico) but never an issue. Now it's a big deal as one yard is saying they can't haul me and another really wants to know weight, telling me they have a hard limit of 26,000 lbs.

Re: Weight of a Formosa 51'?

26,000lbs is 13 tons. Is the haul done on a rail or Travellift? A 35ton travellift is pretty typical. A 75ton Travellift is fairly large. That's assuming the lift is well maintained.
Isn't there an owners group you can get some info from? This link FORMOSA 51 sailboat specifications and details on sailboatdata.com says the design weight is 56,000lbs. Not close to your 26,000 limit. The same displacement is listed here Sail Calculator Pro v3.53 - 2500+ boats

Re: Weight of a Formosa 51'?

These are the stats from sailboatdata.com:

Hull Type: Long Keel
Rig Type: Staysail Ketch
LOA:
51.00' / 15.54m
LWL:
39.58' / 12.06m
Beam: 14.08' / 4.29m
Listed SA:
959 ft2 / 89.09 m2
Draft (max.) 6.23' / 1.90m
Disp.
56000 lbs./ 25402 kgs.
Ballast: 12000 lbs. / 5443 kgs.

Are you sure they said 26.000 pounds? That is less than 12 tons. If that really is their limit, you need to find somewhere else. Even if these figures are wrong, there is no way you will come in under 12 tons.

You beat me to it.
