I was familiar with trolling motors for fresh water fishing but I was blown away when son in law got his new sport fishing boat.
He is never happier unless he has a spear gun or fishing rod in hand or a rifle.
This has a GPS and will maintain a position or follow a track, like drifting over foul ground with soft bait. There is a insulated storage for the catch that doubles as a seat for the helmsman and no other creature comforts. I stay ashore with the frypan on standby.
