[Public-List] Gross Tonnage Measurement

[Don Campbell]

ames I have #528 registered with the Canadian Government but under the 
British measurement system. The first thing you need to check is whether 
the British registry system measured in long tons (which I think they 
did, -2200 lbs)  or short tons -2000 lbs). If long tons are used they 
are the same as 1 metric tonne. the nomenclature on the registration 
form is TONS
    Most of the first column is straight forward but the number of 
bulkheads is none
length from the fore part of the stem to the fore(written in) part of 
the rudder stock is 27' 4 tenths.
main breadth is rounded to 9 feet.
depth in hold from tonnage deck to ceiling is 4 foot 5 tenths
depth from top of deck to at side amidships to bottom of keel is 6 foot 
8 tenths
round of beam 0 feet 4 tenths
length of engine room 2 feet 5 tenths
    If you have an Atomic 4 the registration papers show the bore to be 
2 -9/16
stroke to be 3 - 1/8
N.H.P. is 1/2
B.H.P. is 30 and the next line in that box is 6 knots
No. of shafts one
Gross tonnage under tonnage deck 6.81
deduction to account for space for propelling power  0.25
Space or spaces between decks
Trunks  0.53

Gross tonnage 7.34                 20.77 cubic meters
deductions 0.25                           .71 cubic meters

Register tonnage 7.09             20.06 cubic meters

Note 1 the tonnage for engine room spaces is 0.10 and light and air is  
- tons
Note 2   (stuff not included  etc)  galley 0.16 tons
                                                  Toilet 0.03 tons
Note 3  fees note has a line through it

I hope this shortens you calculation time. Just add a decimal in the 
feet and tenths additions and multiply by 2.54 to get cms and divide by 
100 to get meters if you need to do things in meters.
