127 by 41in dinghy for rowing
This is a small pram dinghy
designed to be built by the same kind of method as my Light Trow - the
lower chine and bottom are built using the age-old skiff method of bending
sides around a central mould, while the upper chines are added later , in
this case using screws and epoxy putty. The screws in this case drive into
the frames at the transom bows and stern, and into the stringer/inwale
seen in the drawings at the top edge of the lower chine.
How will it perform? I've learned not to count on either until these
things are proven, but I hope that with its breadth-to-length it will row
well for a two-sheet boat, and that the flattened central rocker will
enable it to plane when unladen under tow.
The files in this zip package include a small cartoon in gif form, a gif
of the drawings, a dxf of the drawings, and a copy of the .hul file of the
hull form, which was created using Gregg Carlson's Chine Hull Developer
software. If you have trouble printing them out legibly, take the files -
particularly the gif files - to you local print shop for printing out on
large paper.
The measurements are all given in inches and tenths of inches. This a
breach with standard boatbuilding practice, but should present no
difficulties providing you can obtain a ruler with graduations in tenths -
these are normal in the UK and I gather engineers and machinists use such
rulers in the US. In plotting the coordinates that make the panels, I
would advocate squaring off the material in ten-inch squares with the
origin in the bottom left-hand corner before using the tenths-graduated
ruler to plot the coordinates.
NB This is an experimental drawing created by an untrained amateur. The

these drawings, and does not accept liability for any loss or accident
that may occur to persons or to property during the course of construction
or in use.
