on my 5.5, i might be able to point the bows upwind but i sure couldn't sail with my spin floggin me in the face... it would be all over the deck, in the spreaders, in the halyard, in the jib and there would be no way it would snuff.
i am sure i would capsize (or break) with any decent gust around 9 or soooo
I agree with that, in most instances, you probably could luff the kite and let it flog and sail higher...is that seamanlike? (I'm just asking the question).
I spent a lot of time 2 summers ago experimenting sailing with the spi up at high angles to see if I could make it pay to sail lower; but much faster upwind in very light conditions with plans to use it if it worked at that years Piers race; I could sail about 15 degrees lower(but it took ages to get going and I did not have a lot of control).
It was fast in about 2kts of wind; 3kts the traveller was at the end stop and 3-4+ the mainsheet was dumped; anymore and the kite would tip me in. The transition from “some control” to “must bear off RIGHT NOW” was a very small difference in apparent wind; I’m sure sometimes my own speed caused me to have to bear off as the apparent built to the point I was no longer under control!
Sometimes the rudders would stall and I would do an uncontrolled bear off; sometimes the plates would stall and the boat would slide sideways; sometimes the rudders would stall and the boat would slam tack - I COULD tack the boat WITH planning up to about 3-4kts; but not hold head-to or close to wind – it’s a one shot deal to tack.
Not safe to be done around other boats!
