I remmeber the multi ENZA with Sir Peter Blake be in similar conditions , survival conditions , with a tiny storm jib
and some times runing under bare poles towing a drogue, your question if a 40 to 50 ft cata with a storm jib
towing a drogue in 60 ft seas survive depend of to many factors, the cata is a production mass cata , a custom cata? is the equipment
in order to be in such conditions? is a fiberglass
construction or a metal construction? the crew have experience to deploy a drogue? etc...the same questions for a mono.
I be in Biscay Bay with a lagoon 380
in Gale conditions , i never see 45 to 60 ft waves in my life , and is a lot off punisment for a lagoon
to be in 35 to 40 knts off wind so just imagine 60 ft seas, no please!!!! better to be in the bar with friends waiting for weather!! lol.
