Yes why would you. I just want to get some ideas. The concept
is to enter on the ship board computer the destination
port(s) and perhaps using software
sketch of prefered rote. Then cast off and leave the rest to the programme. The system will use GPS navigation
, which will also give ship speed and tidal drift (to be corrected for) it would include electronic maps and location of hazzards. The hardware
would be basically:
(1) Servo controlled tiller (manual overide).
(2) A pair of fan like sales one each side of the mast
with seperate servos to expand the sail out (imagine an inverted fan of triangular cross section) to yield the most suitable 'push' in the given circumstances.
(3) A rotating mast
to align the sail to obtain the maximum power from the wind
. If tacking is necessary then the computer will caculate the course to be followed. Sudden loss of wind
can be sensed and adjusted for. The rotation is obtained by a very large gear wheel
at the bottom driven by pinion and servo.
(4) A vane controlled windturbine which will give speed and direction of wind and supply via generator
top up to ships batteries. Obviously this can be 'feathered' in high winds.Relative wind speed can be gauged by computer from GPS
(5) Since there will be sudden swings of the sail, it would be best if the mast is on the upper deck
with the 'crew' on a lower sundeck.
The whole system relies on storm warnings etc to be 'understood' by the computer and suitable action taken.
