Looking at the USCG Documentation for our 424, it shows the gross
tonnage as “24 GRT” Now really that should be 24,000 pounds and not 24
tons. (The net tonnage is shown as “22 NGT”. I tried to get the Doc
Center to change that as I understand that port fees go by tonnage.
They said since it was originally filed that way that it cannot be
corrected. What does your doc say and has this been a problem in
foreign ports?Thanks,
Pete

None of the islands in the eastern Caribbean even looked that close at the documentation papers.

Silverheels’ Certificate of Documentation says 18 GRT
and 16 NRT. I’ve cleared into a score of countries in
the Caribbean and the Med, and while some forms ask for
one or both tonnages, none have ever charged a
tonnage-related fee. Occasionally there is a big price
jump for length, such as in the Bahamas over 35′ and in
Grenada over 40′.Tonnage fees might well apply to commercial shipping,
but not to yachts that I’ve ever seen.Tor

GRT and NRT refer to volume capacity of a ship not its mass or weight.
From Wikipedia: “*Gross tonnage* (often abbreviated as *GT*, *G.T.* or *gt*)
is a unitless index related to a ship’s overall internal volume. Gross
tonnage is different from gross register
tonnage
.[1] Neither gross
tonnage nor gross register tonnage is a measure of the ship’s displacement
(mass) and should not be confused with terms such as deadweight
tonnage
or displacement .
Gross tonnage, along with net
tonnage,
was defined by *The International Convention on Tonnage Measurement of
Ships, 1969*, adopted by the International Maritime Organization in 1969,
and came into force on July 18, 1982. These two measurements replaced gross
register tonnage (GRT) and net register
tonnage
(NRT). Gross tonnage is calculated based on “the moulded volume of all
enclosed spaces of the ship” and is used to determine things such as a
ship’s manning regulations, safety rules, registration fees, and port dues,
whereas the older gross register tonnage is a measure of the volume of
certain enclosed spaces.”I think the one place this value for a yacht will result in a fee is the
Panama Canal. When I worked in the CZ back in the 70s I remember the
highest and lowest fees were posted in the observation area of the
Miraflores lock. I don’t remember what ship was charged the max, but the
min was for a guy who swam the length of the canal.Regards,

The rating has nothing to do with the actual weight of the boat. It’s a formula the CG uses to evaluate cargo carrying capacity and is related to the waterline length and beam. I think my doc says gross-17.
When hauled with empty water tanks, she tips in at 24000 lbs. I think she actually weighs about 22000 with the balance being fuel, ground-tackle and beer.

Pete,
An explanation of the abbreviations GRT and NRT can be found at the
following link. http://en.wikipedia.org/wiki/Gross_tonnage
My document has these abbreviatiions also.
