A boat that could operate by wind power (sails) as well as by its engines would be the best bet, because gasoline would then just be something that made the boat more effecient rather than a necessity.
The found boat may not have fit that bill, but if you had enough gas you could potentially cover hundreds of miles of coastline. Considering the amount of territory you could cover and the fact that most people were dead, the chances of finding another boat that could operate by both wind and its engines was almost certain.
As for scavenging gasoline, it is no more difficult than scavenging for food or other supplies, which is a necessity. There would literally be millions of abandoned cars and trucks, all of which can be siphoned for gas, not to mention abandoned tankers and gas stations. The Marine Corps recruit depot at Parris Island (just 45 miles from Savannah) would also have stockpiles. Gas would not be in short supply. The main problem would be dealing with walkers or potentially hostile groups of survivors while scavenging, but you face the same risks while scavenging for food or other supplies.
If need be, getting to an island by wind power would also be neither unreasonable nor difficult. People have sailed that way for thousands of years.

How do you plan on getting back to the main land, since you'll be low on gas?
Imo, not a good idea at all.
Getting to an island would be no miracle if you have a fully fueled boat, or one that operates by wind power. There are numerous islands just a short distance from the mainland off both Georgia and South Carolina, both of which are within reach. Blackbeard (the famous pirate) and his crew sheltered on a couple of them.
Obtaining fresh water is going to be a problem regardless of where you bunker down. Your options in either case is either scavenging for bottled water, setting up something to collect rainwater and/or desalinate saltwater, and boiling and drinking water from streams. (or all three) The last of those options, is also the riskiest.
This would no more a problem on an island that it would be on the mainland. In either case, it is going to be one of your main day-to-day concerns.
If sheltering on an island the group's best bet IMO, would be set something up for rainwater collection, a makeshift filter to render salt water drinkable, and supplementing that with scavenged water from the mainland. There are simple setups that survivors can create both to desalinate salt water to render it drinkable and to collect rainwater, both of which have actually been done by people in real world survival situations.
Food could be an issue if the island's soil is entirely sandy or otherwise unsuitable for farming. In that case the group would be forced to scavenge, but that would be no different than if they were set up on the mainland.
So long as you had gas or a boat that could operate by its sails, it would be a short trip to the mainland to scavenge for supplies.
The best bet would be an island in which you could farm. Short of that, perhaps scavenging supplies to erect a greenhouse for vegetables. They could be found in many parts of rural Georgia and South Carolina.
Sheltering on an island isn't a perfect solution, and still presents some difficulties, but no more than would present survivors on the mainland.
The main difference is that on the islands the resident walker population is likely to be either low or non-existant, since many are either entirely uninhabited or very sparsely populated. Your home base with either be entirely safe from walkers, or mostly so. In either case, your home base would not be threatened by the massive zombie herds of hundreds or thousands of individuals that are roaming on the mainland. Those herds are a constant threat to any place you decide to bunker down on the mainland.
