The worst i've been out in was F5 but wind over tide in a tide rip on springs and hail to top it off. Three of us on board when I only had 6Ohp on my 5.3 Humber. We had 18 NM to get back with only a portable GPS without map. It wasn't frieghtening but we took 2 hours getting back and burnt loads of fuel. We were going from l'ile d'Yeu to Noirmoutier for those who know the area.
