The scallop culture fishing is a major fishing in Uchiura-Bay, Hokkaido, Japan, and many small fishing boats are engaging in the fishing. As small fishing boats during fishing operation conditions generally incline from 6 to 10 degrees due to mooring to the culture facilities, it is vital for preventing the capsize to make clear roll motion during fishing operation conditions, especially for the difference of encountered angle of waves. Considering easiness of working on the fishing operation, most fishermen moor the ship to be encountered tides from her left side. We carried out tank tests and measurements by using a full-scale ship to verify the effect for the roll response during these mooring methods. Based on the roll response function and the characteristics of power spectrum generated in Uchiura-Bay, we estimated roll motion experienced in real sea and discussed the safety directions of encountered waves during the fishing operations.
