Last year I built the “UnterSeeBoot” and had some nice hours riding on the edge but the longer I ride the harder it was to ignore the signals of the lower part of my body… so this year I decided to do something for my 51 ear old butt… here it is. It’s made from 10mm marine grade ply and cedro. To initiate the forces to the hull I add two frames between bulkhead one and two and two vertikal knees below the deck at the frame positions. All joints made with epoxy. I add a peace of harder mahogany where I later glued in the oarlocks. The mod adds about 2,3kg of weight, thats worth of it (my butt’s opinion…).
Here you find a lot of photos about the process
My “Drawing”:
Preparing the boards
The board is about 150mm wide and 850mm long
model and one board 
scarfing the edges 
routing just a narrow 10mm deep groove 
the rest was chiseled 
here the result 
fine tune the edges 
drilling holes for screws 
dry assembling
Preparing Frames and Knees
preparing additional frames 
preparing knees, elongate edges 
transmit edges to model 
cut out model 
transmit to cedro and cut out 
prepare for glueing 
all is sanded down at least to the epoxy layer 
cover the varnish
Glueing and Paintwork
glueing 
making fillets between board and gunwale 
coating wood with epoxy primer 
Painting (sanding before…) 
varnishing the clear coat 
glueing oarlocks 
pad for oarlock
Sailing…
From now: Sailing without pain!
