Hardtack
A 25' 4" Flat-Bottom Metal Cabin Utility
By William Atkin
A Cabin Utility in Metal
A small boat like Hardtack, built from iron or steel. has a number of excellent features. Among these the following stand out; the hull will cost much less than one built of wood; it will be stronger for equal weight than a wooden hull; it will stand more hard use; it will not be eaten by marine borers or decay of dry rot; if properly built it will not leak; nor will drying out in the sun and air open seams. A welded metal boat like Hardtack stands little chance of sinking if it is fitted with water-tight flotation compartments of sufficient capacity to float the entire weight of the boat and its equipment.

The deck arrangement shows a short cuddy forward and a big cockpit, this is 11 feet 11 inches long. A seat extends across the after end. The cockpit floor is, of course, self-bailing. The motor is installed beneath a housing which extends two thirds the width across the cockpit, leaving a passage-way along its starboard side. The motor house Serves also as a seat for the helmsman, the steering wheel being mounted nearby on the cockpit coaming along with throttle controls, clutch lever and instrument panel nearby.

Hardtack is of flat bottom model and therefore a very simple form to plank with metal or, for that matter. wood. The lines are the latest development of this type of hull and I know that if the boat is built exactly to the form shown in the drawings of the lines the performance will be more than satisfactory. The length of this cabin utility boat is 25 feet 4 inches; the water line length is 24 feet; the breadth on deck, 7 feet 4 inches; and the draft 1 foot 4 inches. The freeboard at the bow is 3 feet 8 1/2 inches; the least freeboard is 2 feet 4 inches; and the freeboard at the stern 2 feet 7 1/2 inches.

This latest of the family (number 609, by the way) will be an excellent, safe and useful craft in rough or smooth water, and will have ample speed with reasonable power. The motor shown on the plans is a four cylinder 133 cubic inch cylinder displacement Lathrop. The weight of this is 440 pounds, and turning at approximately 2,000 r.p.m the speed of Hardtack should be close to 10 1/2 miles an hour. Any reliable marine motor of from 100 to 160 cubic inch cylinder displacement can be used for power; but I would limit the weight to 550 pounds.
Plans for Hardtack are $100
