A small pram dinghy.
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.
