It's an excellent idea - the local fishermen will know the tides and any local effects far better than the CG computer which will generate a massive potential search area.
which reminds me of a search in Cardigan bay for an overdue 12' speed boat with three teenagers who'd run out of petrol and drifted 20 odd miles downwind of Borth. The CG computer had a Nimrod searching off the Isle of Man by first light. We ignored the 'plot' and flew direct to where we calculated they'd have drifted to. Picked em up early am. No flares or radio. CG astonished that Nimrod hadn't found them in the dark "but they can find a needle in a haystack" said DC Milford CG!
