On Fuzzy I've noticed all 3 windward tell tails on the jib point upwards at about 45degrees to horizontal. All the leeward ones fly horizontally. Is this an indication of a setup issue or is it normal? I've never noticed it on a boat before.

Its not unusual... especially if the boat isn't as flat as it ought to be!

the holy grail. :)

If all three windward jib teltales are 45 dgrees up from the horizontal it means you have the correct amount of twist up the jib.  It also means that you are as close to the wind without loosing power for that jib sheet position.

if you increase the amount of twist and let the top open up the top teltale will lift more or the sail will back reducing the power from the sail. This is all set by the sheeting angle at the clew or (the relative height of the sail up the luff wire to the jib sheet fair lead).

Stu and I (Ross typing) have woken up to torrential rain with sailing kit hanging on the line, and already 19 mph blowing at Grafham with some more to come. After a very manly breakfast of cooked meat with cooked meat along with a splattering of hash browns and I think we'll be ready to go peacefully.

You just need to pull on the cunningham more than you think would be an appropriate amount. We found that the same goes for light wind too, to get the battens across lots of cunningham helps in that situation too.

Glad you had fun though, suicide is a real hoot to sail when the wind is up a bit, and quite comfy when its not!

Is anyone fancy joining us at Grafham this weekend?

We hope to have the upgraded self tacker in place for an early afternoon sail - some company (especially  a member  ::) ) would be grand.

H has a dinner in Cambridge on Saturday evening, so we are modifying the plans to a Saturday session with Exultant.

Adem are you looking for a crew ?

Hmmm, it now looks like work is going to get in the way of a sail. This is a pig as I've been dreaming of my new tacking routine all week ;I(
