ABSTRACT
The slamming problem is common when a trimaran sails in rough sea conditions, especially for the cross deck structure, and the slamming with non-zero angles between the cross deck structure and the water surface will occur. In the present study, an experimental study of oblique entry of trimaran cross deck structure is carried out, and the relationship between angle, velocity and the slamming load are explored. The trimaran section is released from different heights with various angles above the water and falls into water. Then experiment is also repeated for various falling heights. The relationships between the distribution of the slamming pressures with angle and the velocity are discussed, based on the results and analysis, some conclusions are drawn.
