Look on your charts. From how martin and Pete Jnr described it, about 26 miles SE of Poole (SE/SW??) It is an area of very rough ground, as rough as any wreck, and littered with Pollock now, and Cod in a few weeks.
Crusing at 15-18knts it will take around 1.5 hours, stopping for a few mackeral on the way to break up the trip.
First week in June??
