Modern dredging equipment may be divided into four main classes. The grab dredge is used where the amount of excavation is relatively small. It consists of one or more grab buckets, operated by cranes mounted on a vessel or barge or sometimes on the shore. Each bucket has jaws that are hinged together.

How large a boat to cross an ocean? John Guzzwell sailed around the world in Trekka which was 20 feet 6 inches long. Robert Manery sailed across the Atlantic in Tinkerbell, a 13 foot sailboat. Nordhaven 46 foot motor trawlers cross the Atlantic, Bruce Kessler circumnavigated in a Delta 70 foot trawler. Yet it is routine for 150 foot motoryachts to be carried across the Atlantic on Dockexpress type ships. It all depends on how comfortable you want to be and how seaworthy the boat.
