I would suggest that you do several things. 1. Keep the jackline as near the centerline of the boat as possible 2. Find the shortest tether that you can. 3. Get a 2nd tether and find an attachment point such that the two tethers prevent you from going ob. If this doesn''t work, I would do things like drag a
line in the water behind the boat to grab onto. This
line could be attached to the transom
ladder such that when you grab it, it pulls the
ladder down for you. On a tiller steered boat, you could also
rig a
line that trips whatever you use to center the tiller when you leave it unattended. This way, the boat will round up into the wind and slow way down. Good luck.
