For single decked vessels, multiply the length, breadth at the main beam, and depth of the hold together, and divide the product by 95.

EXAMPLE.

The length of a single decked vessel is 64 feet, breadth 22 feet, and depth 10 feet; what is the tonnage ?

As 95: 22×10 :: 64: 1483 tons, answer.

RULE.

For a double decked vessel, take half the breadth of the main beam for the depth of the hold, and work as for a sin gle decked vessel.

EXAMPLE.

The tonnage of a double decked vessel is required, whose length is SO feet, and breadth 26 feet?

As 95: 26x13-half the breadth: 80: 284 tons answer.

To find the Government Tonnage.

"If the vessel be double decked, take the length thereof from the fore part of the main stem, to the after part of the stern post, above the upper deck; the breadth thereof at the broadest part above the main wales, half of which breadth shall be accounted the depth of such vessel, and then deduct from the length three-fifths of the breadth, multiply the remainder by the breadth, and the product by the depth, and divide this last product by 95, the quotient whereof shall be deemed the true contents or tonnage of such ship or vessel; and if such ship or vessel be single decked, take the length and breadth, as above directed, deduct from the said length three-fifths of the breadth, and take the depth from the under side of the deck plank to the ceiling in the hold, then multiply and di vide as aforesaid, and the quotient shall be deemed the ton nage."
