    The Rob Roy/Swift seems to be the opposite, minimal curve = a long part of the lower gunwale submerged and scooping up water.
    Just right! Swift (I.Oughtred's McGregor! - it was my mistake, sorry!!!) canoe has a really tiny of stability - she has no chines and is similar to half of circle in medium frame:




    Japanese canoe Aquamuse is wider, she has higher sides and she has more flat bottom than previous one. In these characteristics she is more similar to BETH sailing canoe which has a good initial stability. But side flotation chambers essential also - see differences of canoe swamping with and without side chambers:

    Generally with Beth I have remounted from the centreboard as the boat comes upright.

    You can also get back aboard with the boat upright if there is some wind blowing and you sit the boat broadsides or close to. I think I have occasionally got aboard from the water in very little wind by climbing quickly over the side.

    She does scoop water, but the cockpit is quite narrow and not too long so it is not a huge quantity of water - and the mizzen really works to keep the head to wind while you bail her out.

    But you want it loose while righting and remounting.

    Thank you Michael!

    Especially my question concerns the stability of the boat after returning to the upright position (unstable water in cockpit significantly reduces the stability). Is she stable enough to skipper came back to her from the water? I'm going to check it out soon (first weekend of July 2011 at Jamno Lake nad Baltic coastal waters). I intend to practice to do well in different weather conditions, especially at a slightly higher waves.

    Howdy Robert,

    On getting back into the boat there is some consciousness required to keep it upright, but with the mizzen holding the boat head to wind it is not particularly difficult.

    When your weather and waters warm up it would be good to do some practices to get a feel for it.

    Thank you MIK!

    Probably if some difficulties I will notice - than I can drop out mainsail which will be heavy if wetted and it's yard is a bit heavy too. BETH's stability with mainsail dropped better is

    Hi Robert

    here's a video of an experienced canoeist practicing capsize recovery. it's not entirely the same as a decked sailing canoe but the way he re-enters the boat is very neat indeed.

    Thank you Brian,
    It looks great (toss of that canoe - especially, which is not way for BETH)
    Yes - climbing on board looks neat indeed.

    Take it easy - often the water is warmer than air.

    ...and he has an appropriate clothing.

    Default I guess

    I guess being a blow boater means you need know nothing about vessel stability and meta centric height!

    That would make sense - because they often know nothing about the rules of the road on the water either - which is why as a rule us stink boaters give em a wide berth wherever possible.

    Why not google the terms "vessel stability" and "meta-centric height" and soak up a little vessel theory - you'd honestly be more stable in a bathtub than that sailboat (and I use the term sailboat judiciously - I'm not sure it really qualifies for the term boat even...)

    Let me guess - do you hand over your can of beer to a bystander when launching her and say words too the effect "here hold my beer and watch this"?

    Sorry I can't help but laugh at this whole thread - what scares me is we could share the same stretch of water one day.

    Cheers

    Fair go! He's a Western Australian stink-boater, what do you expect?

    (Western Australians have little couth - trust me, I know.)

    I own both power and sail, big and small, I've never understood the strange distinction or dissension between the two.

    In my country is similarly...
    This is the reason that each of them respects only their own point of view - I think.
