I would call GT hunting a very active form of fishing in terms of searching and working fish. If you have a spot you want to work, start 100m or so upwind or with the wave direction to work the spot, then once you've gone passed it and covered some ground, then maybe drive around and start again if the structure/current looks promising. Otherwise, just keep trucking on. Put your motor "just" in gear to get an idea of the pace to fish spots (someone at the helm all the time if you can) - that's all that is required. No hits or follows, keep moving on. If its just a small fish, keep going - the bigger fish will make there prescene known when they want to so theres no point pounding the one area for more than a couple of minutes or half a dozen casts as Brandon mentioned.
