Stella Kodiak fisherman Peter Mc Carthey took a bold step. He decided that he needed a larger fish boat so he had the Hansen Boat Co. of Everett, WA sponson the 58ft long X 26ft beam FV Stella to 32ft of beam with a beam aspect ratio of 55%. Many kibitzers predicted a mess. And he had some trepidation as well, but he said it is big water out there.

Happily the Hanson people did a good job with the lines and He chose a DMR rudder. He called me the other day while making one of his first deliveries. He is very pleased. He said that he was able to outmaneuver and hold his position against currents better than boats twice as long. Further he said that he picked up most of 1 knot of cruise speed and she tracks straight!

In Alaska salmon fisheries there is a 58 foot length limit. The term limit seiner refers to a 58 footer and they are very common for this and the fact that for Federal ground fisheries there is a 60 foot limit for participating in certain quotas. The house forward western combination seiner that is as big as possible is becoming the popular vessel. There are presently a number of 26, 27, and 28 beam boats. Now with Peter we have a new goal for extreme beam at 32 feet. Actually at DMR we were already at 29 1/2 feet.
