Abstract
Novelty: construction of a ventilated hull through network of pipes ending in parallelogram-like recesses. Technical features: said ventilation system is similar to whatever polyester construction provided that the mould bears the precise design in relief for being printed on the watercraft’s hull. Purpose: critical reduction of the watercraft’s slip friction and, thereby, reduction of fuel consumption; improvement of the watercraft’s efficiency.
