I am using the Parasailor2 from Istec.
I see several advantages with that design.
Due to the hole in th sail pressure can escape, so it is NOT a lightwind sail but i had it up to 25-30knots of wind
Then the boat is going to fast (surfing at 18knots makes freaking noises on the lagoon)
Below 25knots i can easily bring it down with starting the engines and just give around 8kn of speed with the wind
. This reduces pressure enough to be able to easily pull the sock over the sail.
Only once i had problems where it was more than 25knots and the waves were really horrible. But even there i managed without letting it loose on one side completly.
Some of the pictures are taken with a 10mm lens, so do not wonder why my mast
shows the sock and its shape. Have an oval sock instead of a round one is a huge plus. i can pull it done more esy, less etanglement of the sail itself and easy stowing. (it fits through a normal hatch)
shows a closeup of the flap. Yes it looks flimsy with the thin ropes etc, but so far never one broke or was entangled.
The 105sqm sail works nice on my 38feet Cat. Also when inside the boat i like the 360 degrees lookout because the sail is higher than the windows.
Andy negative things ? Yes, price
and the rigging
of the boat.
I am missing cleats
and the blocks on the bow are almost below the front seats.
For sailing the seats are a PITA or the blocks need to go to the end of the bow. This a friend of mine has already done, so i am waiting for his experience and then when my warranty period is over i will change that.
For the discussion about going dead down the wind. The Autopilot
needs to work more and the sail is bobbing left right a bit more, since i can not get a good angle with the ropes at the ends of the sails
So i prefer a slight angle to the wind, but riding it exactly downwind is still not a problem at all.
How do people do it in big waves ? When getting really fast i wondered if straight down the wind is bad for pitchpoling or if an angle is bad because of capsizing?
Most likely the only safe solution is to slow it by taking down the sail?
Abobe 15kn in surf i have to steer from hand or otherwise i have the feeling some serious stuff might happen.
Curious on your opinions.
