Figures for a Santorin are -
Part 1 brass registration plate on board says 15 13/100 tons
Registration certificate says Gross Tonnage 18.11 and Registered tonnage 15.13
The original AMEL brochure says Displacement loaded 22,045 lbs and total weight empty 18,738 lbs, ballast 8,156lbs.
When hauled out in UK by crane we registered a shade over 15 tons (British).
Confirm previous comments that Part 1 registration refers to an ancient measurement of predicted volume.
If anyone fancies doing the math between all these figures - enjoy!
