[hpv-boats] Directional Prop

[Ian Cassell]

Have just got one of Rick's folding props with shaft.
The shaft is 16mm aluminium solid rod 2m long,
and the flex section is 9mm epoxy reinforced flexible
steel rod. Had the idea if a flexible shaft can go up
and down to avoid snags why not move it side to side
to steer the boat. Tried it out this week and works well,
turns better than with the rudder I had. The shaft is at
an angle of 11deg so curve is quite shallow, even so
needs a bit of leverage to turn it. Have put a post in
the boat design website with some pics and a video.
