That is true.

Most laymen never notice them, but they are there on most A Rated Offshore Catamarans.

Your supposed to attach a line to them from a dinghy before you venture offshore.

Certainly not on Leopard cats - the "U" bolts on the stern are for tying crossed mooring lines. Any pad eyes on the inboard bows are for securing a bow-sprit. If you think you can survive on the underside of an up-turned cruising cat, for any length of time, I think you are living in a dream! Cats normally flip during storm conditions, which will make it virtually impossible to access the underside of the bridge deck, never-mind stay there.

One idea I came across was mounting a jackline between the hulls to act at an attachment point for tethers while awaiting rescue. It could be semi-permanent. I would want to check and clean it before any serious passages.

Any thoughts?

I've seen cats set up with webbing pulled tight under the bridge deck. Obviously tight to underside of bridgdeck is important.

I have used those U bolts for crossing mooring lines. I found them a little awkward to get to.

The Leopard 48 has a escape hatch mounted under the stairs in both hulls. The stairs flip around to provide access.

I am in South Africa in September doing a delivery, I will check with the Leopard folks.

Re: Jackline between hulls.

So this is what you're after? But instead of anchoring the bowsprit, permanently attached to the crossbeam?

If you twist webbing a few times it will greatly reduce vibration, at least it does for webbing in an airflow such as when used to tie down cargo to a roof-rack.

It also makes it much easier to pick up if tight so you can clip in to it.
