Grebe Kayak, Lofting Hull Panels

So far, I have lofted the hull panels and made full size templates of the Grebe.  The Grebe is a kid's size kayak designed by Squeedunk Kayaks.  It measures 13'6" in length and has a 22" beam.  The offsets for the kayak can be found on Squeedunk Kayaks' web page, www.squeedink.com.  Rather than make two sets of panels for the hull, I made one set that I can use with a router mounted with a template bushing to make exact copies.  If I make more than one kayak for the nephew and nieces, it will only take minutes to route more panels.  Other than scarfing the panels, I lofted and cut out the templates in one weekend afternoon.

The day prior to lofting the panels, I scarfed some 1/4" lauan plywood to the appropriate length.  The scarfed panel was placed on top of my work area and two nails were driven at each end of the panel.  A string line was stretched along the bottom of the panel.

A mark at each appropriate spacing was made along the string line.

I plotted each point and drove a nail into the panel at each point.

A line was draw perpendicular to the string line at each spacing measurement.

A 1/4" thick batten was clamped to the inside of each nail.  I used a pencil to mark a fair line onto the panels.  Since the batten is clamped on the inside of the nails, the pattern will be a 1/4" smaller than the full size panel.  That's ok because I will be using a router with a template bushing.  I can correct the spacing with the appropriate size bushing and router bit.
