Time for a new towline; I've chosen the North Water Dynamic Pro
especially for its low profile when packed. The North Water can be worn at the front (attached loosely) to help rolling as I usually surface over the back deck. However, I've made some significant changes to improve the product (IMHO). Note the carabiner clipped into a holding ring ready for deployment.
For fast repacking pull the line in quickly, looping it over your arm...
... fit into the unravelled pouch, roll the pouch up and fasten with the velcro.
