boot-topping

The Sailor's Word-Book

The old operation of scraping off the grass, slime, shells, &c., which adhere to the bottom, near the surface of the water, and daubing it over with a mixture of tallow, sulphur, and resin, as a temporary protection against worms. This is chiefly performed where there is no dock or other commodious situation for breaming or careening, or when the hurry of a voyage renders it inconvenient to have the whole bottom properly trimmed and cleansed. The term is now applied to sheathing a vessel with planking over felt.
