Abstract
Recently, in the Japanese FRP boat industry, a marked tendency to construct still more larger boats or higher speed small boats is seen. The forward bottom shell of these boats has the tendency to be exposed to higher water impact pressure and suffer shell delamination damage or breaking of bottom stringers.
In this paper, special design considerations on the bottom shell of high speed boat are summerized from the “Standard FRP boat construction method”, which is recently published by the standards drafting committee of the Japan Ship and Boat Manufacturer's Association. The basic FRP laminating process and secondary bonding method of joints are related in detail.
