Which company's compressed air docks or blocks have improved to reliably lift and store a 40' hard top express cruiser, 13' bridge clearance, twin I/O drives, 13-foot beam, 20,000 pounds, if any? The floating concrete dock is in mostly fresh but brackish water a few miles inland in south FL. The marina is tidally influenced. The slip is along one side only. No outside pilings exist. Depth is 5'-7'. No canopy. Would you trust it in a hurricane? Deflate it partially or fully in a hurricane and leave it under the boat to prevent the boat from rolling over? Please comment if you have direct experience with a large boat and which company. TIA
