·        Why Buy A Boat Lift?

  • Protection
  • Your boat is securely dry-docked, its hull and out-drive safely protected from wind, wake damage, algae, and marine growth, all which compromise your boats performance, value, and appearance.
  • Security
  • Leave your boat for an hour or a year with confidence that it will remain securely dry - docked.  Number one in dependability since 1964, each HydroHoist is engineered to exacting standards and the highest quality levels to ensure performance and reliability.  Finally, you will rest easy knowing that your investment will remain exactly as you left it, and it will be ready to launch whenever you need.
  • Convenience
  • With the turn of four valves (or push of a button with the upcoming electronic model), you can launch or dry-dock your boat in as little as three minutes.  No more trailering, boat ramps, or hull cleaning.  It's just that easy.  You'll love how much time you spend on the water, enjoying your boat, instead of worrying about maintenance and storage.

·        What is so good about HydroHoist Boat Lifts?

  • For Over 50 Years, HydroHoist Marine Group has been  the oldest and largest hydro-pneumatic boat lift manufacturer in the world.
  • To correctly care for the boat, to provide a convenience for the boater, and to complement rather than complicate the dock structure was the aim of HydroHoist’s inventor – a marina owner and boater himself – and it’s still our aim today.
  • Our engineering staff designs our lifts for safe, sure, confident operation; for correct and safe support of its craft; and for minimum effect to the boat dock or mooring environment. Over the years, we have continued to upgrade and enhance our products to better satisfy today’s boater. Our lifts offer impact resistant polyethylene tanks, all metal parts above the water, and easy, simple, level lifting operation.
  • Another HydroHoist “best” is the resale value of our lifts. HydroHoist owners know that should they want to sell their lift for any reason – upgrading boats, or relocating residence, etc. – they have an eager market of boaters that are waiting for a HydroHoist to come on the market.
  • In any market, there are the brands that are universally recognized as the very best obtainable in its industry. HydroHoist is one of those brands. Why, our name has even been used as a generic description of all boat lifts – even when its mispronounced as Hydra Hoist, Hydra Lift or Hydro Lift, boaters everywhere know that you’re talking about the best in the industry!
