Hi

How do the sections on the Hood seafurl interlocking foil come apart? It's twin groove and aerofoil shape. I have one damaged and need to remove the drum and foil to get to it. The genoa is still hoisted and won't come down so I'll have to remove the drum, foil and sail all at the same time! Any body done this or got any other sugestions?
 
u need to junior hacksaw through the forward / leading, edge of a joint & slide apart .
but first u need to remove the drum ect inc the norseman wedge @ the bottom of the fore stay.
you will see the joint is formed by a strip (say 40 m/m long) with 2 little raised "cheese" shaped buttons that engage in holes in the foil to lock sections together
its some years since i took the foils off my previous boat so its a bit hazy remembering + 1/2 bott Oostendes finest Ch De Marze + 3 biers supervising the barby /forums/images/graemlins/wink.gif
 
Mine has grub screws fastened in with loctite holding the joining strips together. Very hard to undo, and equally hard usually to extract the jointing strips.

Why will the sail not come down? Are you sure it is the foil that is holding it - a bit unlikely unless it is damaged in some way. Check it is not the halyard sheeve that has jammed.
 
Hi
Thats right Harry, the foil is damaged. One of the joints has come apart about two thirds the way up the forestay, the sail is snagging at the broken joint and I don't think the swivel will pass over the break.
There aren't any grubscrews, the joints took like one section clips over the other. It might be easier to see once I get it down.

Thanks
 
Bad luck! At the bottom between the foil and the drum, mine has an alloy tube held in place with screws. Once this is released, it can be slid up the foil enough to reveal the Norseman terminal and drum mechanism, which has to be dismantled - not too easy in situ, but quite possible. Once the stay wire is free, it is easy enough to draw the foil off it, releasing the sail. Reassemble requires re threading the stay down the foil, but I had no difficulty when I was setting mine up.

I guess the whole thing will be ten times easier if you can remove the whole thing from the boat and do it on the level, as you have the full weight of the sail bearing down on the foil once the Halyard is off.

I had a similar problem on mine when a connector disconnected itself, but being a bilge keeler I was able to beach it, release the stay, and pull the foil off from ground level until I could reach the offending section. Getting it back up was equally easy (except the wind had got up and it was leaping all over the place, which gave spectators an amusing 20 minutes!)
 
We have the Hood furling on Cornish Maid. While away recently we lost most of the screwsfrom the lower part of the foil, so that when pulling the furling line, nothing happenned. HWMBO did a temporary fix with some different screws.

Do you know where we can get those screws?

Plan at the moment is to tap UK type metric threads because the thread pattern is one we don't recognise. I wouldn't anyway, but Richard doesn't know it either. /forums/images/graemlins/confused.gif

[/ QUOTE ] Had exactly the same problem with mine: The original s/s screws had corroded the ally, then started dropping out under load....

I completely dismantled the foil, removed all the connectors, drilled out the corroded holes and threads, then re-tapped the whole lot - not as major a task as it sounds as the ally is quite soft and easy to work. I then re assembled the foil using Loctite to ensure the screws stayed put. The most difficult part was grinding down the stock size bolts to the correct length so as not to foul the wire stay inside, without damaging the threads. I found very early on that if the bolt thread was not perfect, the stainless bolt would strip out the new soft metal threads without any effort at all! However, once properly secured they hold very well, and hopefully the Loctite provides a degree of insulation to slow down corrosion.
