Lightness extends this utility’s cruising range as far as an auto-top can take her. She handles motors to 20 HP.

This is a type of hull design suitable for many uses where an easily transported boat is needed. It is an ideal fishing boat for use in relatively protected waterways, and is quite efficient at planing or semi-planing speeds with 5 hp and 6 hp motors; while at the other extreme it may be driven at high speed even in rather rough water with motors up to 20 hp. The hull is a developable-surface design, primarily for planing speeds in choppy water, and though it is somewhat faster it resembles a round-bottom planing hull both in appearance and performance, as it banks beautifully on turns and is quite soft riding. Easy riding and safety at high speeds were the primary considerations in the designing. For use with motors of 10 hp and over, a steering wheel should be used, mounted aft approximately at the location shown in the construction plan; and for high-speed operation the seats should be so arranged that the driver sits almost on the bottom. The high seats shown in the construction plan are for fishing or rowing position and are not suitable for high-speed use. The optional keel, 1¼” to 1%” deep, will serve to prevent any skidding on turns at high speed and is not necessary with motors under 10 hp. A small fin located at Station 6 may be used for high speeds, instead of the deeper keel. The boat is suitable for forward steering with motors of less than 8 hp only. Various types of seating and deck arrangements are practical with this hull, such as double-cockpit arrangements of various sorts.
