Steve there’s a lot of literature about how to run jacklines. A good basic discussion is on the attainable adventure site. We had a hard Bimini and hard dodger. Sometimes rigged weather clothes on top of that. Jack line in cockpit was at bottom of lockers. Six hard points low down to clip to wherever you were. You could clip while in the companionway, move around the cockpit but you couldn’t reach the edge of the decks so no MOB risk. Going forward jacklines were on top of the house. You could use the 6’ tether and the walkways but again couldn’t fall overboard standing or crawling. You wouldn’t reach. Forward of the mast a jackline went to the bow dividing the foredeck in half side to side. We would attach the 3’ and free the 6’ at that point. Again no MOB risk. At any area you where likely to need to work independent of the jack line there was a hard point to clip to. Often used both tethers to remain fixed in place. That made working with both hands easier. Ain’t rocket science. When tethered there should be no risk of MOB. Don’t use wire or dyneema for jacklines. If there’s no stretch you will get hurt real bad if you fall.
