Steve,
We have a similar setup, and this summer tried to find a decent way to store the inner forestay while sailing as a sloop. We simulated having a bracket by curving the forestay near the base of the mast and lashing the curved section to the metal plate of the mast step and tried to keep it tight by using a bungee cord attached to the end and wrapping it around the mast pulpet. I wasn't very happy with the arrangement as it wasn't tight enough.
Our sail maker suggested this type of a curved bracket and I think it's the way to go. I am just not sure yet where the optimal placement will be and how to tie off the end to ensure it stays tight. I removed the turnbuckle so that piece of hardware was not hitting or rubbing against the cabin top, but even so the length of the stay is such that it can't be led straight forward as it overlaps the forward
hatch. I've thought about mounting the storage bracket such that the stay is led forward towards the
hatch and then wraps backward towards the mast, but haven't checked to see if it's feasible.
I know there are others on the board who have similar configurations and will likely chime in with their solutions. (Pictures would be helpful if anyone has a good solution for this)
