River Rat
A 22' Houseboat-Cabin Cruiser
By William & John Atkin
An Outboard Powered Cruiser
Since the publication of the design of Unsanctioned, a 22-foot lightweight outboard cruiser, a number of inquiries have turned up in the mail asking for designs of a typical shallow draft river cruiser; one to match the type of craft associated with the great and small rivers of the middle west.
River Rat, whose design appears this month, one might call a fresh water sister to Unsanctioned. Her over-all length is 22 feet; the waterline length is 18 feet 6 inches; the breadth 8 feet; and the draft, 1 foot 2 1/4 inches. The freeboard at the bow is 2 feet 5 1/2 inches, and at the stern, 2 feet 4 inches. The sheer is a straight line. The speed with a 25 horsepower outboard motor will be very close to 17.5 miles an hour.
The cabin is laid out for a party of four. The deckhouse is fashioned after the manner of most western river work boats. The house sides are high and extend for nearly the length of the hull. Also they are parallel sided. The headroom throughout is a good 6 feet beneath the deck beams.

This latest design shows a scow model hull having enough deadrise in the bottom forward sections to ease slapping when the boat is plugging against a head wind and sea. The deadrise flattens aft which combined with the straight chine lines will prevent the hull settling at the stern while under way at top speed. The nature of a hull of scow form makes it very difficult to provide topside flare. In view of the fact that a boat like River Rat will be used on well protected waterways there are likely to be few days when the going will be rough enough to make the boat wet and uncomfortable. Of course with the windward side windows closed she will be snug and dry inside.

The construction is as light as possible consistent with strength. The planking will be made of 3/8" waterproof plywood.
