Years ago when we were having another boat built to stick on Loch Langavat, the subject of pins or rowlocks came up at the committee meeting.
Much discussion ensued until an ex Lomond fisher piped up "Pins, oars for idiots". That ended the discussion. I do not like pins because it can make trimming the boat difficult as I cannot move sideways to compensate for awareness challenged anglers.
That is true but I used to use my two border collies for trimming the boat!
At least with pins you can let go of the oars knowing that they will still be there when you go back to them. Even in the lumpiest water it is sensible to be out in an oar won't jump off a pin. The only time I ever had an unattended oar come off a pin was when a border collie stood up under it and lifted it off... actually it happened more than once!
Having to sit nearly on the gunwale to keep the boat half level when the rods are fishing is a pain but comes under the "looking after the customer" bit. When the twowts insist on keeping the boat half capsized while you try to row or motor back upwind is a different matter and isn't to be tolerated! I don't like boat seats for that very reason but you have to accept that old bu99ers can't fish without them!
