Gross Tonnage

[garfield]

Hi,
I have a Sun fizz ketch 1984. The survey suggested it has a gross tonnage of 19.07 and Reg. tonnage of 16.66. Can that be correct? It is clearly much heavier than the modern equivalent.

From the data I have the fixed keel Sun Fizz displacement is only about 7.300 tonnes and the centre board version about 7.800 tonnes. 

If the yacht it British registered the registered tonnage may be based on Thames Measurement, which is calculated on volume not on actual weight

I would suggests asking the surveyor to validate the gross weight data
