Gulfstream
The lender has requested federal (Coast Guard) documentation for a new Gulfstream 232, even though the boat also will be registered in Washington State.

The Coast Guard Regs allow for documentation of a recreational boat if it is at least "five net tons," but the calculation is not straightforward.

Has anyone documented a Gulfstream 232 with the Coast Guard? I'd like to, if I can plug in the right measurements to make it work.
 
It is unlikely that a 23 foot monohull will have a net displacement of 5 tons or more. The net tonnage is not the weight of the boat but rather similar to displacement. The manufacturer of the boat should know the tonnage.

One thing that is not clear is whether a vessel with less than 5 ton net tonnage can optionally be documented.
You may want to try calling your local USCG office to see if they can clarify,
I also wonder why your lender is requiring documentation for a small recreational vessel ( it will be a recreational vessel, correct?)

Are you using the boat in International waters? Canada or Mexico?


Coast guard won't document a vessel under 5-ton displacement.

Take the hull weight and add engines, fuel, water, tower, hardtop, fishing gear and anything else that would be on the vessel. See where you get to. Being a new boat the dealer and GW should be able get these numbers to you.

Hull 4,600 - 2x200 engines 1,000 - 141 gallons fuel 350 - 100 pounds water - 1,000 for gear = 6,050.

The lender offers a better interest rate for federal documentation. Extra security in identifying title for their lien over state registration. Yes, all recreational.

Thanks. I could get to Victoria, BC in a few hours of cruising.

The weight of the loaded vessel is not the same as displacement. In simple terms, displacement is how much weight can be added to the hull without the boat taking on water and sinking . The displacement may be greater than the loaded weight calculation you mentioned. The displacement figure for a vessel does not include things like weight of fuel and other tanks, people or gear.
The important thing is to not carry more weight than the specified displacement ( and with a safety margin of course.)

Here's the Coast Guard form for simplified measurement. I'm doubtful that a 9'3" beam is enough width to be able to qualify using this form.

Still wondering if a Gulfstream or other similar boat on the smaller side has managed to qualify.

I sent an e-mail to Grady-White to inquire.
 
  • Displacement:
    .

    This refers to the total weight of the ship, including everything on board (hull, machinery, cargo, fuel, water, etc.). It's essentially the ship's total weight when floating.
The weight of displaced water is exactly equal to the weight of any floating object. The object must be floating and it does not matter how heavy it is as long as your body of water is wide enough and deep enough to contain the floating block of wood or ocean liner, etc.

The boat will displace more or less water depending on what is loaded on the boat (fuel, water, cargo, equipment). If the boat hull were square it would be easy to calculate the cubic feet of water displaced from the waterline to the bottom of the boat. Times 64 lbs per CF you have your displacement. But boats have complicated hull curves that make this calculation difficult.

Agreed, but I believe the number is not the figure needed for classification. The displacement number you calculated changes depending on what is loaded in the vessel. The displacement classification doesn't change.
Here is some info from the Yachting and Booting forum.
As already put, displacement is the weight of water displaced by the underwater sections whilst floating. This is equal to the weight of the boat and everything theron.

Of course there is also 'dry' weight, and 'Tonnage' for registration, which bears no relation to any 'weight' but is a measure of hull volume related to some archaic load capability.

I'm pretty sure that if she floats around her designed waterline, then whatever the designer intended will be fine for the insurance company. I'm equally sure that if you quoted them the Registered Tonnage they would be happy with that.

There could be a factor of 2 between those two figures.
 
He isn’t going to get to 5-ton displacement with a 232. A call into the Coast Guard and maybe they will allow a smaller vessel traveling Internationally. They won’t care about his interest rate.
 
It would be my guess that the lending company just used the wrong terminology in their request. I would guess they want proof of the vessel is Coast Guard "certified", not "documented". All Grady White boats have a Coast Guard placard in the vessel near the helm. Grady White can produce a letter of Coast Guard certification, proving that their design, methods of manufacture and materials meet Coast Guard approval.

Give a call to the lender and make sure the person making the request, knows the difference between certification and documentation of a vessel, and indeed mean what they said.
