just an outside the square option - take your boat across, team up with one of the bigger boats for extra fuel, bunks, showers etc -  during the day they go out and do the 'normal' Kings thang with their crews whilst you and your team (perhaps rotating from the available crew #s) stick around the islands doing what you want to do....meet back at the  'mothership' for a raft up and feed and refuel?.....if you where sticking around the islands you wouldn't use much fuel.....might be logistically and cost prohibitive...dunno bro but just something to think about.....

On our last trip up there on pursuit Ginga we had 5 casting at once with 2 on the bow one amid ships and two at the stern with no issues at all.
Rick got pretty excited with doing this and put Pursuit very close to many guts and bricks.
Very cool way to fish and it takes real concentration to watch your lures as you find yourself watching everyone else,s
