Seiner Over 15 tons

Salmon seiners

Purse seine boats of less than 65 ft. (19.8 m.) in length are too small for herring fishing or packing (carrying), and few have been built in recent years. In the future, all small salmon seiners will probably be of the drum type.

Salmon-herring seiners

Purse seiners of 65 to 80 ft. (19.8 to 24.4 m.) length are used for salmon seining, herring seining, trawling and transportation. The larger boats necessitate a large investment but as long as they can make capacity catches they pay greater dividends, because expenses for fuel and crew are only little more than those for smaller boats.

This class is probably the most interesting to the designer, because of the problems of design and compe- tition between owners to have the fastest boat. This has led to absurd over-powering, particularly in smaller boats. In Europe there has been careful work to improve hull form to get greater speed with the same power or the same speed with less power; in British Columbia the drive has been for more speed regardless of power. But it is reasonably certain that worthwhile increase in speed can only be got by reducing displacement and not by varying the hull form.
