Ralph has been designed as
an open trekking canoe. The client who asked us to draw her
up wanted a large open canoe that could take a family safely
exploring Scottish sea lochs. She therefore had to handle
the short chop and winds that often cut across open sea lochs.
We have come up with an 18’ canoe with a generous 36’’
beam which has a mid section with some tumblehome in it. The
tumblehome moves the point of widest beam down towards the
waterline so increasing form stability and also makes it easier
to paddle the canoe without scrapping the paddle on the gunwale.
In the Ralph design, the tumblehome is combined with a shallow
‘V’ to the bottom to keep the wetted surface area
and therefore the resistance, down and we have used a fairly
fine forward section so that she does not slam in waves. Construction
is based upon simple stitch and tape methods using 4 ply planks
per side (shapes are given on the drawings) and she uses 4
sheets of 4,5 or 6mm ply. LOA 18’; Beam 36’’;
Depth amidships 12’’; approx. wht. 52 lbs.
