Indeed. I think walking the docks would be a uniquely poor way to find a boat
in an event like that, where people are preparing and choosing crew a year ahead and more.
I would get on all the crew exchange forums
(including the one on here), and be sure to describe skills you have to offer. Skippers will be looking for people who are good enough sailors to stand watches alone without anyone having to worry about you, and who have something else to offer the ship. Mechanical and electrical
skills are highly prized, as are medical
skills. A good cook is always welcome, but that's not usually so hard to find. Expect to share expenses -- and for the ARC
, they are considerable.
People participating in the ARC are mostly doing it for the first time, and are generally pretty anal about preparing for it. A berth in a boat which is crossing without participating in the ARC might be more easy going than the typical ARC boat.
