Refresh me,.. can you unfurl all the way now? Complications? Sailshape? Headroom?
I'm hankerin to see sideview shots with the TI sail fully deployed. Would be awesome.
I haven't got any good side on pics yet... but I will.
In answer to your guestions:
Unfurl?-Yes all the way
Complications? A couple:
-building up the mast drum with plastic film to fit the AI and then having to remove it for the TI
-the furling line looks funny wrapped around the mast but it works OK,
Sailshape? Normal as far as I can tell,
That is a heck of a mod for the AI, Stringy! I do worry about the stresses it may put on your "ordinary" AI.
I look at it this way Keith. The AI was designed by Hobie to handle the energy from a certain wind strength. Now I don't know what that is but experience tells me to start furling the sail at around 20knots. There is a margin for error built in as I've been hit by 30 knot gusts with the sail fully out and have had no damage.
With this larger sail I was aiming for better performance in lighter winds. With nearly twice the sail area it should be OK to have all the TI sail out in 10-15knots and not exceed the design specs.
The risk is getting hit by a gust above 15knots and having all the sail out but if I sail with care in those conditions, furl early and release the sheet if needed, I'm hoping it will be OK.
Now I'm no engineer and I'm willing to be corrected if my thinking above is flawed!
