B from Cologne has an interesting question concerning towing a Wisper in assist situations.
In addition to the standard of around the coaming tow lines; we here at FC use the bow line and clip into the perimeter cord. Important to note that the clip in point should be in between the webbing (bow and stern).
Clipping the carbine hook into the webbing may stretch the metal over a LONG towing distance, but this part is easy to replace and in an emergency, this issue should not be worried about. If time is available, loop the bow line through the perimeter cord and then clip in. This will transfer the “jerk” force to the cord, leaving the carbine hook intact.
