My MD has just started a solo rowing trip across the Atlantic, due to last approx 70 days on a 2hr on, 2 hr off rota. You can follow his progress and donate to Macmillan here,

Mentalist.

Looks like he's a bit navigationally challenged at the moment.

Given that I know cock all about the sea or rowing I'm sure he knows what he's doing.

Likewise I know very little about boating but from his blog he planned to head south in search of better seas. He's also in the shipping channels so may be playing frogger with liners and it also mentions some odd currents and big waves in the next week or so.
