Hi Kev & Jo,
He have some experiences with the spifurl, not so much since the wind
adheres to Murphy's law. When we had to go NW, the wind
was NW. Now we have rounded the point of Bretagne, and the wind turned to N and then NE. Because we have to go NE. So if somebody tells you that you can not control the weather
, well it seems we can.
We had no instruction about the use of the spifurl, since on the day of the sea trial there was too much wind.
The first day we left La Rochelle, we used it briefly. I was disappointed because it seemed that you could only use it in a narrow band of apparent wind. Later we have learned better how the use it, and now I am more enthousiastic:
The spi collapsed at lower apparent wind figure because I did not want the spifurl to rub on the railing. Now I discovered that you should raise the spifurl halyard
as high as possible (with a short knot
on the top), so that the bottom of the spifurl come higher; and does touch the railing later.
Also we learned that the spifurl forestay should be loosened during sailing. Gives a better performance. And of course tightened during rolling.
We found that the spifurl can be used up to 80 degrees true wind, corresponding to 50 degrees apparent wind. That is quite good I think, Also we even reached a maximum speed of 80 % of the true wind speed; e.g. in 6 knots of true wind, boat speed was 4.8. This was the best situation, normal was 70-75 % of wind speed. We made e.g. 7 knots speed at 10 knots true wind.
Handling is easy. You can do almost everything singlehanded, only during furling
and unfurling it is nice to have a second person on the sheet.
straight down the wind, and furl with the spi behind the main sail. We were told not to use it without mainsail
. On furling we try to keep little force on the sheet, so that it is rolled loosely; I have the feeling this is better for the sail. We also remove it immediately after use.
A long story. I hope that we can learn something from your experiences. Can you answer?
For all other: while the spifurl is presently in the price
list, it is also possible to order with gennaker
from FP. I do not know what I would have chosen, gennaker
or spifurl, had I known that both are possible. Also I do not know why a spifurl is easier to handle that a spi sleeve system; this seems cheaper to me.
Our spifurl is not very white! See the photo
