Mister Jarvis
A 38' V-Bottom Cruiser
By William Atkin
A Masterly Cruiser
Last month we had Mister Simms, and now it is Mister Jarvis; both nice big motor boats, the former a round bilge model and this a V bottom. The big difference though is the speed of the two. Mister Simms jogs along at a modest 11 miles an hour while the newer sister, or should it not be brother? slides along at a flashing eighteen. And that, if it is really 18 miles an hour is fast going. Somehow we have all gotten to think of speed as not amounting to much of anything unless it is over thirty miles an hour or so. There are however very few cruisers that really go 18 miles an hour. The best way to prove this is to get an eighteen miler and see how easily she flies by most of the fleet.

Mister Jarvis is a 38 footer, having a water line length of 37 feet, a breadth of 10 feet, and a draft of 3 feet. The freeboard forward is 4 feet 9 inches and aft 3 feet 6 inches. There is just enough sweep in the sheer to get away from absolute straightness, and this coupled with the moulded sections will produce a handsome and shipshape looking craft.

In Mister Jarvis I have tried to keep the exterior as plain as possible, believing that this is the best way to build a boat. The after deck is 4 feet 3 inches long and has a hatchway giving access to a handy stowage place below. The cockpit is 10 feet 10 inches long and the floor is well above the water line so as to give folks aboard a show to look around at the sea and get the joy they should. Deep cockpits give the feel of being cooped up. The cabin trunk is 15 feet 10 inches long and not so wide as to cut down walking space around the deck. The pilot house, or windshield, whichever you wish to call it, covers the companion way and does not extend abaft the cabin trunk. The top covers about half the cockpit, leaving the rest open to the weather. A desirable arrangement from a great many angles. There is a rail all around the boat 7 1/4 inches high including the cap.

Going below we find the galley on the starboard side. This is a roomy place fitted with all the things dear to the cook's heart. Three burner alcohol stove, large ice box, sink, drain board, and a handy row of dish lockers along the after bulkhead. Under the sink there will be lockers, and under the table for the stove. There is a locker for fishing poles at one side of the companion steps and a locker 2 feet 8 inches long on the port side; the latter will be about 4 feet 8 inches high from the floor. Then there is the toilet room fitted with a Lee electric closet and wall basin. There is a shelf along the side of the ship under the deck. The main cabin is furnished with two man-sized berths. There are upper berths, which when not in use form backs for the lowers. There is a small buffet one end of the cabin. A drop leaf table is set up between the berths and even then there is plenty of room to go forward. For those who crave lockers the forward end of the cabin will be a sort of little blue heaven, for it is piled full of lockers and storage room; 4 feet long and both sides of the boat. Up under the forward deck there is a place for anchor chains, and if some hooks are put up on the bulkhead they will come in very handy for one thing or another. There never is enough room for everything on a boat.

The motor will be installed under the cockpit floor and should have a bore and stroke of approximately 5 3/4 inches by 6 inches turning about 1,200 r.p.m. This will be about 100 h.p. There is a water tight bulkhead between the engine and the cabin.

Aft, you see, this hooker is different from the usual V bottom model. Here the sections sweep down to the rabbet line which is kept well down on the keel and deadwood. The purpose of this is to permit the motor to be installed abaft the watertight bulkhead near station 7; and to keep the shaft angle as nearly level as possible. Motors do not run especially well when cocked up on one end; and it is also a sure thing that the nearer the propeller shaft is to level the better the propeller functions. You will find that the only sharply curved line in the underwater part of the craft is D1. The buttocks are flat, the chines, and the water lines aft also. The result will be a bottom of good lifting power and that is what is needed when the speed begins to approach 14 miles an hour. The keel runs right aft in a straight line giving protection to the propeller and rudder. There is however no shoe to hold the heel of the rudder because the rudder would be too deep if it continued down to the keel. The rudder is on the stern, which is my favorite location. Somehow this seems to finish off the aft end of the boat and has many very practical advantages besides. John Hanna once said of me in respect to rudders that, "If Billy Atkin ever designs an ocean liner I shall expect to see her steered by an outboard rudder," or words to that effect. Perhaps he is right.
