K1 single-handed keelboat

Thanks for the reply Paul.  So I suppose it would be a bit quicker to hike and keep it upright, but you are less slowed down with a bit of heel than you would be in a normal dinghy.  That should keep the racing tight between the young and fit and the old and wise.

 

Originally posted by Peaky Paul, the video on this page shows a modified NS14 with a similar jib boom arrangement.  It seems to work pretty well. How is the hull designed to work better at an angle of heel?  Are the waterlines a better shape when heeled, say, 10 degrees, or does the waterline length somehow increase? I thought you needed overhangs to get an increase in length?.

Yes, the jib boom looks good on these boats and appears to be the same arrangement as we've used on the prototype, although I can't see if there are any other control lines being used.  Anyway I'm sure we will get the jib boom to work well on the K1 too.

The hull isn't really working better at an angle of heel, just the more the boat heels the more righting moment is gained from the keel bulb.  So the hull has to be effective when heeled as well as upright, as for any yacht.  With a long, narrow hull the underwater shape hardly changes as the boat heels so the boat remains well balanced and light on the helm when well heeled.  Any change in the waterline length will be negligible because of the narrow transom and absence of overhang. 

make it 19'6" long

big assymetric

 

wings to  sit on

 

praps would buy one when i get more wrinkled

 

Jib booms on the N12 certainly didn't work, but on a one design, where absolute speed isn't an issue, it could make sense. If I sailed somewhere which didn't have weed (the Martin 16's really get caught) and shallow bits, I'd be very interested.

Looks fun, but to me the big issue would be when you fell out of it after missing a toe strap. Unlike the 2.4m or the illusion in which you are secure in the hull, if you fell out of this it would probably just sail off a reasonable distance before luffing up!
