When we started the design for the 11' Oregon Peapod, we had thought to design a
transom stern boat, as a bigger version of the 8' Portland Yawlboat. They were
both commissioned by the same builder, who wanted to have a line of dinghies to sell. However, as I got
further into doing the designs, it occurred to me that we could design a double ender. I did some preliminaries
of this and sent them to the clients. They liked the idea, and we went ahead with the double ender instead of
the transom stern design.
|Design Number 149|
I saved the drawings for the transom stern version. Some time later, we finished them up for another client who
built her as a dinghy for the 50-footer of our design he was building. He reports she's a delightful boat.

|Length overall||11'-0"||3.35 m|
|Length datum waterline||10'-0"||3.05 m|
|Estimated structural weight||110 lbs.||50 kg.|
|Displacement, to DWL||452 lbs.||205 kg.|
|Displacement-length ratio||202|| |
|Sail area||80 sq. ft.||7.43 m2|
|Sail area-displacement ratio||21.73|| |
|Prismatic coefficient||.560|| |
|Pounds per inch immersion||144|| |
|Entrance half-angle||25½°|| |
Note: The displacement numbers are calculated to the arbitrarily chosen DWL.
The calculated ratios of displacement-length and sail area-displacement will vary widely
depending on the loading of the vessel.
