Silvertooth, could you clarify if you actually mean
sailing on canals and rivers, rather than motoring, rowing, paddling, pedalling? I have to say that the prospect of actually sailing on canals, particularly in a boat as large and as unfocussed on performing well and pointing well under sail, and particularly if you are thinking of sailing on the particularly narrow, shallow, (keels/leeboards!) shopping trolley filled (keels/leeboards again!) UK waterways, fills me with horror! I appreciate that the French and European canals tend to be larger than ours, but unless the wind is well aft of abeam, the difficulty of this, and lack of space to manoeuvre is going to be a nightmare, especially in something that isn't a 'pointy yacht type design'. Worth just google image searching 'canal sailing' and seeing if you can find pictures of a vessel larger than a dinghy sailing on an actual canal.
Maybe a (sea going) barge, and carry a mirror dinghy on the roof for fun sailing when the opportunity presents itself?
I did find this rather lovely blog, of a rather different but appealing approach, albeit with a much smaller (and pointy!) boat, with a lot of specialised equipment. Worth a look.
