My Blade isn't made of carbon, doesn't have Ashby sails and wasn't made by Dynautic, but minor inaccuracies aside, great to see a well-written bit of class promotion in Y&Y.
Where do you buy Y&Y from? I can never find it in Smiths...
It would probably take a few more years to reach me if Mark hadn't posted it here. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

True - you guys have plenty of other UK magazines, but I can never find Y&Y in Schiphol either...

Some of it springs from an Email "conversation" I've had with Jeremy Evans (the author) over the last few months, Some is from the F16 submission John did for the year end edition and some he did himself.
There is more on SCHRS in the April 6th Edition, and I managed to get the F16 mentioned in that as well <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
I'm also trying to get Jeremy up to Grafham to have a proper chat about SCHRS and also take him out on my boat. Just got to find time for it all !
Question, "fire and foreget rotation" ? ? ? How does that work ??
Sounded like a good idea at the time....But I've not sailed the boat enough to work out if it helps.
I have 2 systems for controlling the mast rotation.
Course tune: rope goes from the side decks, then under the tramp to a hole and then up, thru a block on the end of the spanner and then back down and to the other side; this is the "course" tune that allows me to dump rotation at the windward mark as the spanner will rotate to the max.
You can see the cleat and turning bock on this pic:
Fine tune: There is then a second system for fine tune (upwind) where I have a pair of cleats on the mast spanner and a second (blue multi coloured) rope that leads to the shrouds.
You can see it clearly here and you cal also see then end of the red rope coming up thru the tramponline
So get around the windward mark and let the mast swing free by uncleating the red rope on the side.
At the bottom mark, you pull the red rope and you go back to the same setting you had at the windward mark.
you can then move mast rotation at by pulling the blue rope from the wire.
On the red line course adjustment, is the cleat what Ronstan calls a "V cleat" and if it's released when you hoist the chute and jibe after you snuff then can you get the red rotator line to catch from the new windward side....?
And 2), does the blue multicolored (coloured) fine adjustment loop back to the other side stay...?
It looks like you have some good ideas here, mine is not satisfactory as I tend to sit on or bump the cam cleats as I'm tacking and in high winds that's a problem.

Yes, there is a V cleat both sides and so the line is double ended; you will notice there is a double ended block on the spanner (red goes round one block facing down towards the tramp, blue around the other).

Yes, the Blue multi line goes to both side stays so you can adjust the rotation from the wire.
I wouldn't buy it. I acquire it through a friend of a friend who I believe has a free subscription due to his Scoring Software. Thus, it can take a little bit of time before I get to look at the pictures and check out all two pages dedicated to Cats.
just before I sold "Altered" I set up a similar system on it. I highly recommend this set up, it makes it very easy to look after your mast downwind (lot's of rotation)when it's windy and you have little rotation upwind.
I followed Greg G's lead on this as he was using it on his F18. My rotation was set off the boom, so you came in to release it a single cleat on the boom, which tied to the pulley which the normal rotation rope went to. As usual I should have taken a photo <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />.
Being set up so it can only be adjusted from the boom, didn't seem to be a problem as I was usualy in the middle of the boat to uncleat, before pulling spin up and recleat after dropping spin. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
That would only allow you to pull it on, and anyway there is another cleat on the other side...
Well that was my thought. I'm probably missing the point (Oh where is "the master of the obvious"?). When tacking especially after a spinnaker run I seem to have more to do than I have time or energy. If I can manage to stay out of the water then I give my self a little congratulations. That is until I look over and see the anti rotator is free and I'm trapped out or about to. I don't know if I would need the cheek block to allow me to engage the anti rotator from the high side or weather yanking on line (red) that is running under the tramp would be enough to engage the 'V' cleat. The system that I'm envisioning would replace the 'V' cleat with a swivel cleat, probably cam cleat, so that I could adjust the mast rotation from the wire.
Are there any links to Greg Goodall's F18 rotator that TwiceBitten is referring to?
