Abstract

This invention discloses a boat and especially to the one suitable for sailing on ice, whose minimum water level and maximum water level left and right sides a quarter flow angle is between the twenty degrees and twenty six degrees to effectively decrease the resistance on the ice sailing and the push power needed by the boat motor and ensure the drainage volume of the boat.

Description

technical field [0001] The invention relates to a hull, in particular to a hull suitable for navigation in ice regions. Background technique [0002] Ships sailing in ice areas have significantly greater resistance than ordinary waters. In order to sail in ice areas, they must meet the requirements of the Finnish-Swedish ice class regulations. The propulsion power required by the main engine is higher than that required for non-ice navigation. The power is much higher; the higher the tonnage of the ship, the greater the propulsion power required. For example, for a 50,000-ton tanker, the propulsion power required for conventional non-ice navigation is about 10,000-11,000 kW, while the propulsion power required to meet the Finnish-Swedish ice class specification is about 20,000 kW. Under normal circumstances, the time that ships need to sail in non-ice areas is much longer than the time that they need to sail in ice areas. very bad. Contents of the invention [0003] The...
