Shrinking p-lines (bridle line connecting front and rear) is the most common problem on the old BWS. Don't know if the symptoms fit, but worth a check. There are lengths available if you search the forum.
... I agree, bridle shrinking,,, plus of course not pumping them it up enough.
I can't say for sure as I don't own a BWS but I do know from other bridled kites that the lines can shrink after some time, especially if they have been worked a bit.
Generally what can happen is at one stage or another, say kite has been dropped in the surf, and you get a shock load on the bridle line where the line is stretched or rather put under excessive load. It gets a kind of fatigue and that bit of the bridle then goes back to its slack state before it was treated by the manufacturer, ie the pre-stretch comes out. So it now shrinks back to its pre-stretched state and becomes some what spongy and mere cm or 2 can mess it up totally. I think its only 2% of total length but its enough to f up the kites performance.
I reckon a lot of kites can be ressurected from death if they had new bridles put on,,,, or at least you could get more use out of them before you chuck 'em out. Try a new set of lines on ya kite and it'll feel like a new kite.
Maybe see if you can get the bridle measurements from somewhere and check it out, get back to us and let us know!
