@AZMark I pack 10 PFD's (4 watersport jackets, 2 neoprene jackets, and 4 stand Type III around the neck) and 1 Throwable PFD on a Rope and 4 Auto Inflatable Mustang Survival MIT 100, fenders, rope, lines two anchors, a porta potti, the cooler that came with boat, a smaller cooler, the table, the front cushions the rear center removable cushions, Wakeboard, ZUP Board, 2 water ski's, spare oil, small toolset, umbrellas, flares, 2 fire extinguishers, an emergency throw bag, first aid kit, backpack with emergency gear, a large floating waterproof bag (for all clothes and towels) and a food bag as well as the bow snap cover and pool floats. Also in the ski locker I have two oars, an extension pole, Super Mable HD 3 Person, and a 2 Person Frenzy tube. In the front anchor locker I have tow ropes, tube ropes and extra tube and tow ropes. I also have a 5 gallon bucket and a 1 gallon bucket. I also throw in the Dewalt Bag that holds my cordless air pump. Finally for the boat I have two rectangular flat containers that carry extra spark plugs, a NOCO Jump Starter, fuses, netting, and other miscellaneous things for fixing the boat.
Believe it or not I have extra room for more crap if need be. This is my standard boat inventory with 4 or 10 people.
Everything above is stored in all the compartments. So basically none of it is visible and believe me you wouldn't know any of it was on their by looking at the boat. If guests bring backpacks they go under the Passenger "J" bench seat. So we have full walkway room and everything is actually pretty spacious. Getting things in and out can take a few minutes but I have no clutter in the boat and when full doesn't feel overly crowded.
It is really amazing how much storage the AR210 has, I never would have guessed.
