G'day Matt and Paddlewise,

Wouldn't a paddle fitted with one or two 3 axis accelerometers radio linked
to a data logger let you calculate this? And the centre of thrust move in
the paddle with time?

A friend fitted his paddle with a two axis accelerometer many years ago and
still has it available. We're talking about using it with TORSON to simulate
the forces involved in kayak injuries but I think 3 axis will be necessary.
I'm told this has already been done for rowing and running. Has it been done
for kayaking?

All the best, PeterO
