How’s this for a start?
The video at the bottom of this post shows the Mod 1 version of the jackline / tether system that I have been thinking through. Before watching it, you may wish to review this post for background.
- Key design consideration is to prevent the person that is clipped in from hitting the water. While I have yet to test this by actually hanging overboard, I believe that the objective is met in all but one or two spots.
- The line being used for the jackline in the video is just an old sheet that I found on board. It is just for planning purposes. The actual material that we will use has yet to be determined.
- The tethers shown are climbing slings. Again, used only for planning purposes to work out the length.
- I chose to fix the jacklines at the mast to minimize overall stretch, and keep them close to the center line of the boat. While this does necessitate a tether change to go forward to the bow, I believe that the number of times this would be required (when sailing on a boat with a roller furling headsail) is much less than the times required to go to the mast to reef, etc. It is a worthwhile tradeoff IMO.
- I opted to use a remote tether at the mast instead of a two-part tether.
- While it may have appeared to be cumbersome to make the switch at the mast, this was the first time that Rebecca had run through it, and the tethers being used were just improvised from climbing slings and carabiners. I’m confident that with practice, using the finished product, the result would be much more streamlined.
In just a few minutes, Rebecca and I will be heading off to hike to one of Grenada’s many waterfalls. Feel free to add your thoughts to this post while we’re out getting sweaty and muddy.
