depends on the size of the halyards, pennants or whatever.
I just had to buy one for my new set up. Looked at Spinlock's etc, but settled on a simple Barton clutch for about half the price (£30 ish IIRC). Works absolutely fine, just for the topping lift.
I currently have all my reefing lines on winches at the mast base, plus main and genoa halyards led back, but onto cleats, therefore needing the winches.... so looking at putting 4 cluthes either side for heavy(ish) loads.....
NAS,
I am happy with my Antal 8-14mm triples on the coachroof, and a lot cheaper than the Harken gear on the other side. They dont have a sudden drop off like the Harken, but similarly they dont have a real positive click when they are engaged. 125 quid a pop.
Think the Harken is better, but will I ever wear them out on a cruising boat? No I didnt think so either. 170 quid a pop.
Spinloxk XAS 6-10mm on my furling line and Cruising chute tack line do just fine too. Single about 55 quid I think.
But you know the morass of lines coming back over my coachroof... /forums/images/graemlins/smirk.gif
Pardon me stating the bleeding obvious ..... you need to think about the geometry and layout of all the new deck fittings before drilling the first hole. I fitted new stand-up blocks and organisers in additional to the new clutch, so had several holes to drill.
I found I could work out exactly the best place to put something on the deck, then I went below and removed the head linings, I found there was something in the just the wrong place. Eg an internal piece of timber framework or whatever. So I had to replan each item to suit.
Depends on the individual boat of course.
Now .... about sucking these eggs, granny ......... /forums/images/graemlins/wink.gif
I'm planning on fitting an organiser either side, and then clutches along each side, but then need to consider where they can actually be mounted, as opposed to where I would like them mounted.... I am thn hoping to add winchers to teh two coachroof winches, and replace the main genny winches with ST winches.... and relocate them at the same time, to give a bit more space for sitting on the side...
