Because I know (a) very little I can only (b) understand a little of what I
hear. I just got back from sailing this rig and I'm trying to make sense of all the stuff that happens. I didn't get to read all these great messages before I went. I did sheet it in tight and often lost momentum and had to turn off the wind and/or paddle to get moving again. Raking the leeboard back seemed to help to. It seems I may have too big of a poorly shaped leeboard. It was a blast sailing downwind and moving back made the paddle more effective but I still thought I might break a paddle. I do appreciate all the advice. I kind of thought I was learning on this trip so I might be able to ask better questions. But if you think I still need to learn more, I'll tell my wife I need to go away again. She'll probably would agree, in theory. "Old Nick" wrote in message ...

It seems I may have too big of a poorly shaped leeboard. It might be possible to take advantage of tumblehome (where the sides curve in at the top on some canoes) to angle the leeboard out a bit as is done on the oringinal Dutch sailing barges. Barend Migchelsen claims it makes them more effective. His website is probably still active although he hasn't posted in this newsgroup for over a year now. It was a blast sailing downwind and moving back made the paddle more effective but I still thought I might break a paddle. sounds like excessive weather helm (broaching). It was a big problem on the Blue Canoe I made out of plastic barrels. The sail was rigth at the bow of that narrow boat and it had no lateral resistance except the paddle at the stern. Try letting the sail out to dump wind - less power, more control. Always have to be ready to let the sail run out on a small boat to avoid loss off control to the wind. There's not a lot written about sailing narrow boats like canoes. A sail with a mast sleeve can be free to rotate right around the mast. The sail can be let out before the mast like a spinnaker. That way broaching and "death roll" are avoided. Death roll is where the boat starts rocking uncontrollably from side to side under the influence of the sail downwind but it can be controlled by letting the sail go forward and dumping wind. There is still lots of wind in the sail for an exicting ride. I've been able to sail my small boats in strong winds that way. I wrote an article about it for DuckWorks. I'm working on a larger version of a rotating sprit sail for small boats, this season's tyvek sail on my website. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

![]() when the sail is balanced you will not need to use the paddle except to tack. a rudder won't help. on a ballance rig the rudder is almost neutral, just used to turn the boat. on an unbalanced boat using the rudder to compensate just turns the rudder into a drag. sail balance is the key. put the mast where it's most convenient in the boat and move the leeboard back more in relation to the mast than what you have now. don't be concerned about moving the leeboard back more than you'd think proper. when you get excessive lee helm it's time to move it forward. I'd start with the leeboard under the back edge of the sail. I found moving the centre of lateral resistance six inches on the Dogskiff made a difference. anything less wasn't noticeable. there is an area for the leeboard relative to the mast where your canoe sailing rig is be in balance. the canoe is only 18 ft long. you will find it eventually. ![]() -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

I'm getting it.
On a 16 1/2 foot canoe I could put the sail 2 -5 feet from the bow and then try to balance it by moving the leeboard fore or aft. I hope to sail with camping gear or more likely, kids. What might be the effects of weight in the canoe and sail placement? "William R.

With such a tiny draft movement with the boat can even make the boat come about. A traditional boat in the Northeast, (Thousand Islands area, I'm spacing the name.) was sailed without a rudder. Coming about was accomplished by movement within the boat. Good luck with your experiments. Sailing canoes were very popular in the 19th century. Don't understand why they are not more popular now. Myself, I would rather sail than paddle!! |

I've seen photos and a description of the annual St Lawrence skiff races. They were long narrow rowing boats with auxilliary sails. During the races the boat were tacked without rudder or paddle by heeling to leeward and moving forward to depress the bow which I guess might lift the stern shortening the waterline length to ease pivoting the hull.

I appreciate the variety sailing adds to a canoe. Carrying a sailing rig in a boat which is portaged is a nuisance which I try to overcome with the simplest most compact removable rig I can dream up. Paddling allows a person to look around which is nice along the shore and on rivers, and to read and run fast water. Sailing requires constant attention to the sail due to changing strength and direction of the wind. Playing the wind is a nice change from paddling and it is more insteresting on open water where paddling in a wind is both tiring and boring. A terrific combination IMHO. I find that going out on the same water most of the time I don't see much new and interesting along the shore and tend to do more sailing. However I do like to explore creeks and rivers under paddle power. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

A traditional boat in the Northeast, (Thousand Islands area, I'm spacing the name.) was sailed without a rudder. Coming about was accomplished by movement within the boat. So loading the canoe and moving the people is part of sailing the canoe. With kids I've learned you lean one way and point the other as you say "look at that". I've seen photos and a description of the annual St Lawrence skiff races. They were long narrow rowing boats with auxilliary sails. During the races the boat were tacked without rudder or paddle by heeling to leeward and moving forward to depress the bow which I guess might lift the stern shortening the waterline length to ease pivoting the hull. So loading involves leaving room to move yourself or others to steer. This is getting more interesting all the time. The canoe has three cross members and two fixed seats (not used when sailing). I like the idea of having a crew to help steer. I'm going to teach a whole new generation because it is not going to be a lost art. Good luck with your experiments.

However I do like to explore creeks and rivers under paddle power. My biggest issue is getting the time and interest of the kids to go out exploring. I've used food and try to make it fun but competition is tough (going to the YMCA or local amusement park instead). I hope that the excitement of sailing will get them. We got towed upwind on our local lake and they enjoyed that but I saw it as a failure of my ability to sail upwind, hence all my questions. We do paddle or float down the Little Miami River. We don't have two way rivers (without alot of tracking and hard paddling) around here. -------------------------------------------------------------------------- ---- William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

I hope to sail with camping gear or more likely, kids. What might be the effects of weight in the canoe and sail placement? you may already know that when two people are paddling a canoe, especailly an empty one, the weight is concentrated at the ends. it's good for steering but it is not the best weight distribution. when one person is paddling an empty canoe he or she sits in the centre. this is a better weight distribution as it leave the ends empty and bouyant. as more weight is added, be it kids or cargo, keeping the weight centralized would also be best for sailing. steering under sail using sail balance with or without a rudder does not require sitting near the end. as can be seen in photos on my website I sit on the bottom and use a backrest when sailing. I pulled a back muscle trying to sail sitting on the bottom without a backrest. the backrest is positioned so my weight is centralized in the boat. I'd sail for a while without a backrest until body position for good balance is known. on the 7.5 ft boat the backrest is a permanent aft deck. on the 11.5 ft boat the backrest is removable and rotates to change the angle. TF Jones uses a rope and canvas backrest on his Tuckahoe 12 narrow sailiboat which he sails sitting on the bottom. sitting on the bottom (on a cushion) keeps the weight low and is less tiring than sitting up and moving one's weight around all the time to compensate for the sail. I don't have enough sail on my boats to sit out on the gunwale but that is how to get more speed and excitement out of the sailing if desired. I've seen photos of canoe sailors sitting out over the side just like other small boat sailors. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

Thanks for the info and more important, the encouragement to keep working at
a silly thing like using everything you know to do the best you can. I don't have tumblehome but could angle the board regardless. I'll probably wait to try that as it involves changes to the hardware. I did keep the sheet in my hand and dumped wind (and almost alittle more during an accidental gybe in the channel leading out into lake Erie). I did'nt experience "death roll" but mostly excessive weather helm. I'll search for your DuckWorks article. Again, thanks. "William R. Watt" wrote in message ...
