My jackstays run to the forward end or the toe-rail, which is an aluminium extrusion forming part of the hull-topsides joint and perhaps the strongest point on the boat. Once clipped on to the jackstay, I have free movement everywhere forward of the cockpit; in fact better freedom of movement than was available with a longer safety line and the jackstays running along the toe-rail, as I then had to unclip to get round the shrouds. The least secure location is the foredeck, where the jackstay approaches and then terminates at the toe-rail, but the freeboard at that point is more than a metre from the toe-rail, and more than that from the top of the guard-rails and pushpit. I use an integrated harness and lifejacket (the newer compact style which fits higher on the chest), with an attachment point roughly at my breastbone and double crotch straps, so I can be reasonably sure that I will hang from it with my legs down; my centre of gravity is well below the attachment point. There is rarely any reason to be on the foredeck under-way - all my reefing lines, sheets and halliards come back to the cockpit; it is only when deploying my cruising chute that I need to be forward, and of course that only happens in benign conditions.It would be interesting to see the layout of your boat. But to be able to stand and have a hook point, whether it be a jackstay or hook point within less than 1 metre from your chest, when standing,of wherever you are- and still give you freedom of movement is very clever. How does it work on the foredeck? You should share it with us please
Oh, another factor is that neither my wife nor I are very tall - I am about 5'6 and my wife about 5'2. And I don't mean a metre as an exact measurement - I haven't measured them exactly, but they are around a metre long; perhaps 4' (sorry - mixed units!). Further, the jackstay runs at cabin top height for most of its length. And our freeboard is high - I've never measured it, but even amidships it must be a metre, and more at bow and stern. At the stern, when standing on the sugar scoop a few inches above the waterline, the deck/hull joint is at chest level.
None of this provides absolute security - there ain't no such thing. I don't rely on any of this working and observe the golden rule of one hand for the boat and one for myself; like a mountaineer, I try to have three points fixed at all times. But I have done my best to ensure that as far as practicable given my style of sailing and the design of the boat I have reduced the potential for an MOB as far as possible. It's also not a static thing; I am constantly on the lookout for ways to improve things; for example, last year I started to work on single-line reefing for my mainsail as the previous system didn't work well for single-handed or two-up sailing, requiring a hand at the mast and a hand working halliards in the cockpit. Not sure I've cracked that yet!
I realize that my style won't work for everyone - a racing crew or even a larger cruising crew would find it very limiting, and there would be a high likelihood of lifelines getting tangled etc. But as I sail single-handed or two-up mostly, it works fine for us. And given that I am sure that in our circumstances a MOB would have a very high chance of resulting in a fatality, it is something both my wife and I take very seriously and constantly look for ways to make it more secure.
