hyperopeEdchris got me thinking- I think I only secure the boards with the side loaders, but they can be pulled straight out. Any suggestions as to how to do it differently? I'm seriously looking forward to another thing to add to the already time-consuming rigging procedure.

BTW- maybe all the recent rains will bring the GA/SC lake levels back up so we can get the cat in the water instead of the mud.

the f18 sailors at my club tie the blades together then put one under both the hiking straps

so i was looking at it today and found some more questions.
can some one describe the jib halyard, i thought it would be like my 16, but there is a block on the wire then the one end of the line ends at the block with a bowline the other end goes threw a v cleat.

that block is not supposed to be there right?

is that line and blocks on the boom supposed to be a boom vang? and do i tie any thing to the rotator bar?

The block is used to double the purchase on the jib downhaul.

Some used the block on the rear beam to double the purchase on the main traveler.

The boom is upside down. the line and block is part of your rotator and should be connected to the "rotator bar".

There is no block block on the mast.for the jib I must be missing it. How do I set up the block for the traveler?
And the boom is not upside down because the outhaul is on the top right now.and the only spot for the.main block is on the bottom. Were do the rotation lines go? Thanks

Do you have the two manuals from the Albums- Tech? Most of what you need is in them, though the photos are a bit grainy.

Jibs are item 60 in the second manual.

You aren't missing anything. Some boats had a wire block on the mast with the wire part of the jib halyard going thru that.

Some had the wire block off a pigtail on the fore stay. It sounds like that's what you have. I've hunted for a picture for you but have yet to find one. Look on page 8, standing rigging picture 2, you should have something like that. http://www.clublocarno.co…ocuments/NacraManual.pdf

In Pic 2, the blocks and red line on the port side of the mast are your main downhaul, but I do not see a mast rotation control arm attached to the mast?

Is that rod sticking out of the sail track just underneath the boom some kind of improvised rotator arm? if so it looks like the block and line running underneath the boom would attach to the end of the rod using a shackle through the hole on the end of the rod.

PS, that rod dangerously sharp sticking out like that, how is it attached to the mast?

the dangerous rod is the early mast rotation 1975 - 1977???

my 1982 has a wishbone with a crimped end and a small block, sharp and still dangerous if a novice tries to stay on the tramp during a pitchpole..

from about 1984 the wishbone was as the above pic, fully bend to shape with a nice smooth end needing no block... would still have your eye out but wouldn't puncture the skull...so if you are going to pitchpole, stay off the tramp....and if you have novices on board who may try to stay on the tramp during a pitchpole, don't sail that aggressively that it's possible

the saddles/eye-straps on the boom are for a 2 into 1 purchase for the outhaul, is that not in the manual?

a very basic old pic of a 1982 5.2 here

http://www.thebeachcats.c…ctures/?g2_itemId=101126

basically you will need a small floating block and a short length of line

do you have the standard chainplate adjusters on, you can use longer ones or even double up if you have to ?

can you lower the mast ball?

the mast needs to be loose enough so that it auto-rotates when tacking

if, when tacking and gybing, the mast automatically rotates as the wind hits the other side of the sail

with mainsheet released

it's ok
