    Default Making a Sailing Rig

    I've been doing a bit of research on canoe sailing rigs, from Iain Oughtred's MacGregor to Hugh Hortons Bufflehead, and everything in between, however in the end I decide to go simple first to actually see if I liked it before getting more than toe deep

    A very well respected Oz designer Mike Storer has a simple drop in rig that he has developed, more for kayaks than canoes, but it seemed it would work with my MR Reflection 15, so I bought the plans (came via email as a PDF) and set to work.

    Once I looked at his original layout, I couldnít see how I could make it work over the length (15ft) of my canoe, (having to maneuver from a sitting position in the bottom at the rear quarter of the boat to the front quarter over a kneeling and portage thwart to adjust things like leeboards, downhauls and halyards didnít seem to me like a good idea in a canoe 30Ē wide) so I laid everything out in Autocad, and started changing things!

    Using Todd Bradshaws book I worked out the CE of the sail (in the end I got it wrong, I was 17mm out), and used that to place the mast thwart, having already decided to centre the leeboard thwart in the middle of the boat.

    Next I didnít have the time or the inclination for making a set of wooden mast and spars, so I opted for aluminium tube, I found a site clickmetal which would deliver small amounts at a very reasonable delivery price, 1 ĹĒ 16swg for the mast and 1 ľĒ 16swg for the yard and boom.

    I had previously been checking out ebay for dinghy bits and pieces, and had bought a job lot of pulleys, deadeyes, cleats etc, so I was sorted for them, last thing was wood.

    Falkirk wood supplied all the ash, even squaring and planning a length for me, really good customer service, Iíve already talked to Andy about supplying Douglas Fir and Western red cedar for another project.

    My local Beatsons supplied the exterior grade 6mm and 9mm ply I decided to use.

    And I used the chandlers at Port Edgar for any st.st fittings and the various cord/ropes I needed.

    Ready to rock;

    Components;


    Ali tube


    Sail design, the addition of spar bend etc is well explained here, polysails, I used the balanced lug.


    Initial layout


    Cut out


    Lofting floor (living room floor)








    Thereís quite a bit of the sail build I didnít document, the tedious zigzag sewing (by machine) the triple reinforcing everywhere, and adding the grommets, to be fair it didnít really take that long, as usual the preparation took the longest.

    The thwarts were fairly simple to make, finding fair points to measure things from was more taxing, the mass produce aspect of this canoe showed itself here, some careful measurements were taken (and to be frank probably not really required) to acquire the centre of the canoe, from then I used this as the datum.

    The mast thwart set up ready for drilling. ( I found this the most aggravating part of the build, the hole saws I bought were garbage, the didnít run anywhere near true, so in the end I used an undersized Forstner bit and a pillar drill sanding attachment to fit it to the ali tube.


    Next up was the leeboard, Mik had very definite ideas on what a leeboard should look like, (basically a symmetrical naca airfoil section), so I glued 3 sections of 6mm (5.5mm actual) ply together, let them cure while I made a jig for my ĹĒ router to create an airfoil section. It was my first time using gorilla glue, and I screwed it up, not enough coverage, unfortunately this didnít become evident until after the foil was half shaped. No choice but to make a new one and start again.










    Again thereís quite a bit missed out, I sanded the foil, then used ronseal exterior grade varnish to seal it. The brackets etc were from Groovski, I drilled out the rivets and reused the various bits and pieces.

    The leeboard thwart was a simple ash plank bolted using the existing portage yolk holes to the canoe, then Groovskis leeboard thwart screwed to it, (not the best arrangement but all I had time for)




    Again thereís a lot not documented, simple stuff like the holes required in the yard, boom and mast for various ropes, cleats etc, making a mast foot and installing it with a slight rake to the rear, fitting the various bitís and pieces to control the halyard and downhaul lines;


    Also as you can see from some of the photos I took the ever real threat of a capsize in the middle of a loch seriously, and added 2 dinghy floatation bags, rated at 45kg each. I used ďpĒ clips from stagonset to fit them to the gunnels.

    So mast, boom, yard sorted. Sail sorted. Rigging sorted. Leeboard sorted, flotation sorted, whats left? Stearing, I really wanted to fit a stern rudder, but there just wasnít enough time so I opted for using a paddle and a thwart with a rowlock;


    Wasnít very good but it worked after a fashion.

    I also added some webbing to help spread the load from the sail throughout the canoe;


    When I was sorting out all the components at Glenfinnan I found that the mast foot had come unstuck, and was gone, so an emergency one was made from spare foam kneeling mat, this worked so well that it didnít move a mm over the course of the week, pretty impressive.

    We're not looking at a lot of money here, use pine instead of ash, cheaper still. The trill of barrelling along upwind, with the port gunnel, almost submerged is indescribable, huge grin factor. Give it a go.

    Here's the youtube video of the trip, along with some shots of the rig in action

    PS I've already started making a proper rudder;






    Cheers

    Hi,

    This looks good. Well done. The video is excellent and the rig seems to work well. Have a look at the OCSG website. You might consider adding cheeks to your mast thwart if you have trouble with the step falling off.

    I would say that the at the moment you could improve the rig by changing the steering system. The paddle arrangement means that the boat is trimmed a little too far back. This is particularly important when you are going upwind. My rig was like this until one of the OCSG guys told me to get my weight in the middle and then get the controls come to me. This obviously means some sort of proper rudder arrangement like a push pull thing in the Todd Bradshaw book.

    The best tihing to do would be to attend a OCSG meeting. You will get good advice there and will have the chance to look at how other people have rigged their boats.

    Remember that if you do go for the rudder thing put the gudgeons not the pintles on the boat or you might get it trapped if you paddle it in a river!

    I am currently rigging a Pelican canoe for expedition sailing following the demise of my beloved Pyranna Prospector. I am not really interested in paddling the thing but I have a feeling that it might make a good sailing canoe. I will be sure to post.

    Good luck with your canoe sailing.

    Cheers

    Charlie.

    Cracking set up Stephen, some great linkys for investigating, thanks for posting them. I'm quite liking the canoe sailing thing too but don't think I'll go as far down the road as you have. Poor Shewie, hope you guys give him a tow when he needs it

    Happy
    Cheers,

    Alan

    No need to worry about Rich, he was waaay in front most of the time, I did enjoy my first experience sailing tho, I'm booking RYA lessons at Port Edgar, get some proper instruction.

    Default Trim

    I know some people use a jug of water to help out with trim - so I can only guess that's why you have a bottle of beer in the end of the boat...

    Thumbs up Excellent !

    Great rig,
    I,ve got a similar rig on my Wenona prospector 15 ,
    I didnt go to the trouble of making a sail and spars ,
    I bought a spar set and a sail from an Optimist dinghy on ebay,
    I also bought a sail from someone on here ,
    I borrowed a leeboard and rudder set up from fellow member on here , Brandon and the set up is very similar to yours ,
    I,ll be making my own leeboard and rudder based on Brandons design, but with a few alterations to better suit my boat ,
    I attended the canoe sailing group meet in Bala earlier this year ,
    They are a great bunch and helped me sort out my rigging and gave me loads of hints and tips , a very friendly and helpfull gang ,
    I,d recomend attending at least one of thier meets
    I,ve recently got my hands on an old wind surfing board and rig ,
    Thuis looks like a great rig to make a few alterations and make it fit my canoe ,
    This ones a bermudan rig obviously so should be even faster and a lot easier to reef in whilst on the move ,
    really enjoyed your Utube video ,
    thanks for sharing ,
    Noel

    You have done a really good job on that. I liked the video too, what was the song on it?

    Thanks guys, I've been looking for an Optimist rig, but I guess they only come up occasionally.

    The video was my first attempt, as plainly shows, the music was a version of "Highland Cathedral".

    I knew the tune but had not heard the words before. I have now googled the history of it and am impressed with how it has evolved. Thanks for bringing it to my attention.
