(plans coming soon)
Welded 5052 aluminium hull being
rotated upright the shape is based on
two break-formed sections (see drawings). Pre-forming the sections
eliminates the need for framing during fabrication.
Aluminium was my material of choice
because of its resistance to destructive corrosion and rot. This
boat will be in the water all season a muddy creek (Ransom Creek)
that flows into Tonawanda Creek which is a section of the Erie
Barge Canal near it terminus in Buffalo, NY.
These are the internal frames
that will provide hull stiffiness. The knee in the frame is intended
to stiffen it an become seating supports. They are made of fir
2x4’s screwed and glued. They are then coated with a waterbase
interior polyurethane because they will remain protected from
Leak testing the hull with 8”
of water. Minor leaks are found and marked the hull drained and
the welds corrected. Waterline welds are primed to provide additional
insurance to leaks. In three years the only water in the boat
came from above.
Frames installed in hull and attached
to welded brackets (not seen in
Interior construction of cedar
decking and Luan underlayment all sealed with the interior waterbased
polyurethane. Decking is held in place with stainless steel screws.
Boat side solid sections are tounge in groove western red cedar.
Now moved out to finish construction
because of limited ceiling height. Center section of the roof
is framed in cedar and covered with galvanized corrugated metal.
Sides of the roof are clear fiberglass corrugated panels fastened
to aluminium ribs.

windows but sitll giving creek tours on a
