cease to be valid and shall be delivered up to and cancelled by the
certifying authority.
(2) When a ship is transferred from the Malta Register the
International Tonnage Certificate (1969) shall cease to be valid

decreased net tonnage shall not be issued until twelve
months have elapsed from the date on which the
current certificate was issued.

Great care is to be taken in completing the Certificate of Survey (Tonnage Measurement)
and Surveyors should carefully note that no alterations are permitted on this Certificate and if
mistakes are made, it is to be re-typed or re-written.
The Surveyor should note the following when completing the Certificate of Survey
(Tonnage Measurement):
( a ) Under the heading "Whether a dumb, sailing, steam or motor ship how propelled", a
ship propelled solely by sails is to be entered as "Sailing Ship". If a permanent motor is fitted
to a sailing ship the entry is to be "Sailing and Motor: Single Screw". In the case of a vessel
provided with a portable outboard motor the correct entry is that applicable to the vessel
without the motor, with a qualification "fitted with portable outboard motor" eg. "Dumb fitted
with outboard motor" or "Sailing fitted with portable outboard motor". When the main
propulsion is by engine the entry will be "Motor Ship, Single Screw", "Motor Ship, Twin
Screw", as appropriate.
( b ) Under the headines "Where Built" and "Name and Address of Builders" when the
hull has been built in one shipyard and the vessel fitted out at another, both places should be
showm under the headings, eg:
Where Built: Hull: Southampton
Fitted Out: Poole
Name and Address of Builders: Hull: Boatyard Ltd, Southampton
Fitted Out: Yacht Fitters Ltd, Poole
( c ) Under the heading "When Built" should be shown the year in which the ship was
launched or entered the water for the first time or when it was completed, which is the earlier.
( d ) The description under the heading "Rigged" should describe the arrangement eg.
"Yawl", "Schooner", "Ketch", etc; if a sitip is not designed for sailing, and is not rigged for
that pupose "Not" is to be inserted.
( e ) The description of the "Stern" should be "Straight", "Raked", "Clipper", etc., as
appropriate.
( f ) The description of the "Stern" should be "Counter", "Cruiser", "Transom", etc., as
appropriate
( g ) The description of the "Build" should indicate construction of the hull i.e. "Clencher"
for in and out plating or planting or "Carvel" if flush; w,here there is a mixture then "Part
Carvel/Part Clencher" should be entered.
( h ) The entry as resgards "Framework and description of ship" should describe the
material of the hull and the type of ship; i.e. material should be shown as "Wood", "Steel,
"Glass Reinforced Plastic", etc., as appropriate.
( i ) The entry in respect of "Number of Bulkheads" should relate to the complete
bulkheads bounding main compartments up to the deck level. If no complete bulkheads are
fitted the entry should be "None".
( j ) The particulars of the propelling engines should be completed if an engine is fitted
inboard. Particulars of motors are not to be showm. The "Description of engine" is to be kept
as simple as possible and yet fulfill the function of accurately defining the type of engine
fitted. In most ships, it will be sufficient to insert "Internal combustion engine". The engine
power shall be the total of the maximum continuous power expressed in kilowatt(KW). In the
case of multiple engine ships, the combined engine power is to be quoted.
( k ) Where numbers are required to be inserted in respect of decks, masts, bulkheads, sets
of engines, shafts and cylinders, these are to be written in words; numerals are not to be used.
