9' Pacific Peapod
Seven years after we'd done the 11' Oregon Peapod, another builder asked us for a smaller version.
(Many designs are commissioned this way, with someone seeing a boat they like, and then asking for a boat like it either
smaller or larger. We also get commissions for modified versions, and some of our designs show different construction plans.
These result from people wanting to build the boats in differing methods. If we think the request is reasonable, we're usually
happy to undertake the commission to convert the design.) The original plan was to produce this boat in fiberglass. As
occasionally happens, their plans got delayed and they haven't built the boat yet....
|Design Number 228|
However, I've liked the design well enough to have speculated the time to finish off the construction detailing. The photo
shows one built by Larry Sweet as a tender for his Cascade Classic 39
pilothouse cutter of our design. She was done with foam cored 'glass construction as is his 39.
The construction called for is cold-molding, which produces a light and strong boat. This is probably the best choice for a
one-off, if the builder is not experienced in other techniques. She could also be done in lapstrake, by the stripper method or
in foam-cored fiberglass.
The daggerboard slot comes down alongside the centerline skeg, so this will not have to be weakened with a cut through it. A
tee shaped slot cap should be made for use when the boat it being towed or under outboard power. This will keep water from
splashing through and eventually flooding the boat.
If she is to be towed, the towing eye should be fitted about three inches above the datum waterline (noted as DWL on the drawings).
This will help hold her head up making towing easier. Be sure to through-bolt the towing eye to a backing plate for maximum strength.
|Length overall||9'-0"||2.74 m|
|Length datum waterline||8'-6"||2.59 m|
|Estimated structural weight||90 lbs.||41 kg.|
|Displacement, to DWL||270 lbs.||123 kg.|
|Displacement-length ratio||213|| |
|Sail area||58 sq. ft.||5.39 m2|
|Sail area-displacement ratio||22.21|| |
|Prismatic coefficient||.58|| |
|Pounds per inch immersion||108|| |
|Entrance half-angle||26°|| |
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.
