I am interested in the design of daggers and what creates the differences. For example, when racing, or following technically, Tigers on my TheMightyHobie18 it was obvious that the Tigers would lift to weather in a puff and my 18 did not. What about the foils creates the lift? Is there a way to modify an old design, like the TheMightyHobie18, daggers to create the same lift? Is it the length or width that makes the difference? I have thought of creating sleeves for my 18 wells that would accept the newer designs but thinking about it is as far as I got.
