Solent Inner Stay

Do you have a Solent Stay? I am looking at installing one.

Curious as to how you tension the Solent stay when in use. When not in use my forestay would have 2,500 lbs tension. When in use what should the tension of the Solent stay be? Whould the Solent and forestay share the 2,500 lb load equally of a percentage of the load?
Regards

Re: Solent Inner Stay

Re: Solent Inner Stay

Where are you tacking that new Solent stay?

Please visit my blog. It's fun to read.

Plan is to install a double pad eye (rated at least 10,000 lbs) about 3 feet towards the stern from the existing forestay. The pad eye would be secured and reinfored to the bulkhead of the chain locker with a stainless steel brace/backing plate. Brace would be through bolted into the chain locker bulkhead with a backing plate. Will reinforce deck at the pad location for good measure. Solent stay would be connected to mast abut 12 inches below mast top- still looking into the type of fitting at this location.

Solent Stay
Yes I found that site in a search- has some good information, thanks.

What I am confused about is what tension the Solent should be. The more tension put on the Solent, the less tension the forestay will see. If you tension the Solent highly, the forestay tension could go to near zero (seems this could lead to forestay failure if the forestay has slack in it and fails due to fatigue failure). Or if the Solent is not tensioned high enough, this could lead to sail shape problems.

Plan is to only use Solent stay for the hank on storm jib, or in the case of roller furler or forestay failure. Most of the times Solent would be disconnected and stored at the mast.

Re: Solent Inner Stay

I wouldn't do it that way. I'd kleep the tack as far forward as practical and drop the head down. If you have double spreaders I'd drop the head to the upper spreader where it is well supported. If you have single spreaders maybe you're better off doing it your way and keeping the head high. If you drop the head more you may end up needing running backs. But I think of a Solent stay as a way to get area forward and low so you maintain good helm balance while reducing the heeling moment.

If you have a stout mast section I don't think you will have a problem tensioning the stay but levers can only do so much and if you are trying to beat in a gale with a solent staysail you are going to need some tension on it to keep the luff straight.

It always surprises me when people ask these questions but don't include what kind of boat it is. For some odd reason I'd think the type of boat would be an important factor in making this decision. But what the hell do I know?

Best of luck with your modification. I hope you have a good spar maker/rigger handy who can help you.

My understanding is a Solent stay means it is connected to the mast no more than about 3-6% below the top (there are some other factors I will consider, but will not go into those) so that running backstays are not needed. I do not want to install runners. It would not be prudent to install a inner forestay at the lower spreaders without additional support of runners at the point of connection- that could lead to mast failure. The lower point of connection for the Solent is a far forward as I can go- other wise I end up in the chain locker. I have a good rigger- me!

Apprently you did not read my OP question. I did not ask how to tension the Solent, I asked how much tenstion. Always surprises me how people get off the OP on sailnet.

Re: Solent Inner Stay

No, I read your OP question. And if your new Solent stay is that close to your masthead I think you can tension it just like your headstay without fear of distorting the mast in that short section. That question I think will resolve itself when you try and get some leff tension on the staysail. Your proposed rig is very similar to my 50'er YONI although we carried the working jib on the inner stay and a larger genoa on the headstay. And no. Having the head of the staysail at the upper spreaders makes sense because that exactly where the mast is supported.


What kind of boat are we talking about?

Boat is an S&S 34 mast head sloop. Single spreader with fore and aft lowers.

Re: Solent Inner Stay

I'd guess you have a pretty stout stick in that boat. I don't know a way of giving you a number for the load on the stay. I think you are just going to have to do it initially be feel, pretty much the way you tune any mast and then fine tune once you have sailed with it.
