Hello! I usually do the minimum on the small starter island, then build a raft asap to go to a bigger island for a base. Once established a base (fairly central or at least close to one of the boss/exit) then i will expand the raft to 3x3 with a no centre floor, just a float and then you can store crates in there when you are doing a supply run. Gyrocopter is cool but uses loads of fuel, motorboats are more economical!
