My Aus blade had the exact same system at Zandvoort, but its fixed to the boom. Its great for quick firing & quickly setting back to original position.

You can an extra cleat to make the rotation system adjustable & quick fire at the same time.

Where does the board attach to?
What runs through the block?

I am interested in such system, but looking at the arrangement alone I cannot figure it out.

Will hopefully have pics this weekend.

Gill has a neat mast rotation quick release system on his Blade. Similar idea, but mounted on the spanner. I'm thinking of doing something similar... Do you have any photos, Gill?

Paul

Paul,

Once I get it working, I'll make you one if you want - Cost plus a small charge for my time. Either Just the plate's that you can drill and then re-seal, or the full monty !

Send me the colour reference no ! (in hex !)

Hi Paul,

Attached you can find a picture of the system. Not a very good angle, but it should do. I will take a better picture this weekend (if we're going to sail).

Regards,
Gill

The board bolts thru the tramp (there is another one underneath.

I'll take some pics on Sunday.

I have fitted a turning pulley (with cleat) under my boom and then
instead of shackling to the rotation spanner i,ve tied a rope to that rotation pulley then back through the turning pulley .Then when you get to the top mark you simply uncleat the turning pulley (rotation out)When you get to the bottom mark Pull the rope back to the saddle where the rotation used to shackle to and your set

OK, set it up today, but DID not sail.

First pic showing the fine tune (from the wire) line (pink). Spi Downhaul (red) and the red/yellow course tune going aft:

[Linked Image]

second picture showing upwind sailing setup. Red/Yellow rope is cleated and the spanner is changed via the fine tune (see above).

Now below you can see that the Red/yellow rope is in tight and cleated; this rope then exits the cleat via an eye and then goes to a double ended block that has the Spi downhaul attached, it then is tied off on the other side of the trampoline:

[Linked Image]

Now loking at the 3rd pic, you round the windward mark and pull the red blob on the end of the rope, this uncleats the red/yellow rope and allows the rotation all the way out (but in the pic it is still on the tramp). Note that the double ended block is now down by the cleat.

[Linked Image]

You now get to the leeward mark and need to drop the kite, so you pull the downhaul (red rope) and in the process this pulls (via the double ended block) the red/yellow course tune back in. You are now back into upwind mode.

[Linked Image]

I'll be testing this in a couple of weeks time.

I am not too big of a fan of my mast rotation set up- seems like I am always scraping along it when I come in from the trap and then get to the new windward side to realize I pulled it out of the cleat. I can tighten it up again but then it is all on one side which makes it difficult to release on one side. But anyway...
this set up looks a little complicated and certainly seems to crowd the tramp. Interesting though.
Now that I look at it some more though... quite an ingenious set up. takes some slack out of the spin downhaul also?

Remember my boat is optmised for single handing, I don't have to have room up front for a crew; I already have ideas for phase 2 as I think getting to the

blob

will be a PITA when it's howling...

Hi Simon,

You're setup seems indeed a little crowded for 2-up sailing.

Regards,
Gill

It is; I usually sail single handed and so the saving of the rotation coming back in automatically when the kite comes down is good for me.

Anyway Simon, it looks very ingenious and I really wonder if it works flawless.

It does.

Worked well today, but it was blowing real hard and so was not forward to let it off much. Will revise to make it easier to do from further back. Have far too many other things to worry about today as it was howling big time and gusty and shifty too.....
