Pretty sure there is a 'Small Boat Angling' club in the country somewhere, maybe try contacting JimC from the forum here(?):
memberlist.php?mode=viewprofile&u=18I used to have a dinghy that I used for pollack fishing along the shore. I got caught out one day when a wind picked up out of nowhere, I took my life in my hands getting back to the harbour i'd launched from. Sold the boat straight after.
Dinghys are only suitable for really calm days in the sea IMO. Or really sheltered areas. Up to you..
good luck
