Sidedeck Jacklines Worse Than Nothing?

We at AAC have long argued that sidedeck jacklines (jackstays) are not safe because of drag risk.

But PBO are taking that up a level by suggesting, based on some very sobering testing as well as even more sobering analysis of sailors falling overboard and being dragged by their tethers, that it might even be safer to not be clipped on at all than to use a standard-length tether clipped to a sidedeck jackline.

We agree with the problem they identify, but feel we have a better and well-tested solution that reduces drag risk to near zero while still staying tethered.

Read the Practical Boat Owner article, highly recommended.
