Surf Scoter 22 Design Notes

It has been over 20 years now that we first conceived of and built the first of our venerable Surf Scoter 22 vessels and it was high time that we sat down to the drafting table, put the thinking cap on, and re-think and re-conceive the design.  Many things have changed over the years and in today’s world its almost impossible to buy a 2 stroke outboard engine, the 4 cycle outboards have taken over the market, and brief forays into small diesel inboard land and larger diesel Stern drives have all come and gone.  What makes the most sense in today’s market with the cost of everything boat related in the far stratosphere price wise, is to use the wonderfully quiet, smooth running, and efficient 4 cycle outboards that are so available these days.  Mounting them on the transom makes the most sense and gives a cockpit that has the space to accommodate everything in use from the fisherman, to the long distance cruiser.  In this new model we stretched the Pilothouse and added a neat enclosed head, so that those skippers amongst us that desire our first mates to come along on our cruising adventures will be comfortable and agreeable!  There is still plenty of room for a galley, helm and co-helm seats in the pilothouse with 6’-4” headroom.  Under the foredeck sitting headroom in the port and starboard berths and with a filler plugged into the middle a huge double berth can be made up.

This new model is quite a bit wider than the older version and the resulting stability will be appreciated by all.  With a 90 hp. Outboard on the stern the top speed is 26mph. and cruising speed of 18 mph is quiet and economical with a fuel burn of less than 4 gph. At speed.

The plans are complete for both professional and home builders and we offer them in both measurement formats our venerable feet and inches and Metric for those of you that can’t do mental math.   Plans cost is $225 dollars and we are very pleased to have had the chance to revisit this old concept, throw a couple of new ideas at it and hope that you will love the result as much as we do!    –Sam Devlin

Dipper 19

Dipper19ForeAft

Above, Nick Lee rests in his Dipper 19, after a lengthy build in a commercial parking garage.

Originally designed to fit in a 20′ shipping container, the Dipper 19 is roomy inside, with a couple of other noteworthy features. The first is her use of twin 4 cycle outboards on the stern. There is no burying of the outboards in a well or trying to disguise them they are mounted proudly on the stern. Part of this plan is to allow them to be de-mounted for the container stowage, but the other part is to allow them to be as efficient as possible and allows for the increased maneuverability of the twin engines. By placing one engine in the forward and the other in reverse the boat can be turned neatly in a tight circle and if you need the other direction to come into play, then reverse the process and she will turn about the other way. With twin 10hp outboards, the fuel burn at 6 knots speed will be something less than 1 gallon of fuel per hour for an efficiency of 1 gallon of fuel burned for 7 miles of travel. At top speed, the twin 10s will offer 10 knots of speed and twin 15s would offer 12 knots of speed.

The cockpit is left open and unencumbered by seats or other appendages. The whole idea is to have a couple of comfortable folding chairs that have the space of being used in the cockpit well without restricting one into one position or another. Flexibility is really the key! With this arrangement, it leaves enough open space for the two outboards to be laid on their sides for transport.

In the cabin, there is a standup galley that has all the ingredients necessary to function and forward under the trunk cabin, there is space for a porta-potti and twin berths on both sides really a remarkable amount of room inside and out for a boat under 20ft. in length. In the evening, the port-potti could be placed in the pilothouse or cockpit and the filler used in the berth area makes a large almost queen sized bed.

The Dipper 19 is available as study and full construction plans, and as a precision CNC cut kit.
