I have 2003 Calabria Cal-Air. Still playing on how to weight it best for wakesurfing. It has the 700lb. Pure-Vert Internal Ballast which has 2 350lb tanks through the boat, a 540lb. launchpad bag, and a 540lb launch pad Recliner.
My thoughts are the bag in the trunk, and recliner next to the engine compartment on the side we are surfing, and the Pure-Vert Ballast filled on the side we are surfing.
Any thoughts or suggestions?
