after initially trapping with he extension underhand i've now swapped to doing it overhand and resting it on my shoulder when sitting on the hull, it does seem more comfortable but you need a well fitting pfd

when first doing it and wearing my old loose fitting lifejacket, that rodes up, a couple of times when i came in off the wire and thought i was resting the extension on my shoulder it had actually threaded itself through the arm opening of the pfd and i hadn't noticed

until i trid to scoot under the boom and found i couldn't swing the extension behind the traveller

made for an interesting few secs as i fumbled around putting the boat into wind to take the jacket off and unthread it.

pic attached shows how close extension end is to shoulder opening when out on the wire and overhanding it
