This summer I've planned to build a sailing canoe (a Crazy Canadian Canoe Craft
). What I'd like to try is putting outriders on it for stability. The centre hull (picture below) is cheap (about 220 dollars) which is why I'd like to use it. Time is a problem for me so building a hull from scratch is out of the question, furthermore I don't have the knowledge. For rigging I'd like to try a windsurfing mast and sail, one of the largest models, since I've got it already.
Firstly, will I need a centreboard on the main hull (canoes drift sideways pretty fast) or will a centreboard on each outrider provide enough sideways resistance with relatively good properties? By the way, I'm planning on using 20cm piping for them and just fix the fore and aft for hydrodynamic properties.
Secondly, Canoes are normally a bugger to turn even with two people on paddles and I'm wondering if the thing will actually be able to tack. If this is due to the "keel" that goes the whole length of the hull it could perhaps be rounded of to reduce sideways resistance and rely solely on the centreboards which the boat can the "pivot" around for fast turning. Which brings me to the next question.
What can I do about steerage. Some kind of rudder I'd like but if this is positioned at the very back of the canoe will it work at all. Because it might be necessary to have it under the stern as opposed to behind the stern. This would reduce wave resistance but it would also be significantly harder to build. A third option would be to have a rudder on each outrider but that implies some added implications of construction.
Lastly, the idea of using a windsurfing mast and sail sounds strange probably, but it would greatly reduce costs if it were possible. If possible I'd like to not use stays other than one to the front of the boat so a staysail could be rigged. Stays are a hassle when assembling or dissembling the boat for transport.
Summary of Questions:
Centreboard, main hull or outriders?
Turning and tacking too slow?
Steering effectively and the rudder(s)?
The windsurfing board rigging?
Any help is greatly appreciated, and thanks for reading my post =)
