Did a trip out of there last winter. Was basically a drive around what looked to be a well worn circuit, there was a groove in the water from past trips. They had a plan, their gear, about 5 anglers so you were on for about 45 mins. A small yellow fin came out of a patch of bait fish. It was nice to have a look around, some of the reef washes looked interesting, but we paralleled some distance off. Departed on the minute, arrived back on the minute.
If there was a few of you with a plan they might do something to order, I'd ask before I got there.
At the same time a bloke from the time shares at Musket Cove, casting poppers off the rocks over a few mornings, had hooked 3 or 4 GT's. Nothing big, but sounded like fun.
Important to note, you could buy beer wholesale from the bar at Musket Cove at about the same price as the mainland shops at the ferry terminal.
Good luck, FT
