| MaxCapacityJonboat is the most boat I could get out of one sheet of
ply. The sides and transoms are of 1x lumber, with the whole sheet of ply
for the bottom. The bottom is stitched and the rest is glue and screw. The
waterline is at a displacement of about 935 lbs. Short and stubby, it can
carry a serious load of cargo, but wouldn’t row very well. It really
should be used with a motor. Note*….The
offsets for the side panel (Below) should be plotted on some cardboard or
paper and then used for a template. The program that I used to develop the
boat does some peculiar things to this kind of shaped boat: it tilts the
side panel as it develops it. The bottom rear of the boat is lifted by
over 5 inches.

All measurements are in inches.
The end points of the plotted lines are joined by a straight line.
This shows how the measurements are used to lay out the
panels. X and Y are the bottom line of the panel and X2 and Y2 are the top
line. All points are from the edge of the ply or a baseline. Any points
which are N/A are not plotted. They may just be not on the panel or are
not important to that line. The two end points are closed with a straight
line.
For information on Stitch and Glue, please check the construction of
fisher10. The hull was done entirely with stitch and glue, except for the
transom/side panel joint, which was first attached with screws and then
filleted on the inside and taped on the outside. There are also many good
sites with Stitch and glue information.
www.bateau.com has an excellent primer on the subject, so do most of
the other major plans dealers, such as Glenn-L and Clark Craft. |
