I've had her in 10' seas. I don't venture very far off shore, mostly in the Puget Sound or the Canadian Gulf Islands (east of Vancouver Island). I typically put 800-100NM on the boat/year (~100hours). Unless I'm in a hurry, which is almost never, I cruise the boat at ~8K's. I do very little fishing (tough to fish and run boat this size at the same time and wife does not like/won't drive while I fish.) but tons of crabbing from the tender (dinghy). Most of my fishing is for Salmon, which requires down riggers that the tender will not accommodate.
