Sealift FAQ's
1. How does the SeaLift Hydraulic System work?
The SeaLift uses one hydraulic cylinder to raise and lower tender/pwc in and out of the water. As the unit is lowered, the tender/pwc is resting in the chocks and stays level as it enters the water. As the unit continues to lower, the tender/pwc floats free, allowing access to the swim platform for your enjoyment. When the Sealift is raised, the self-adjusting chocks center the dinghy or PWC. As the unit is raised, it keeps the tender/pwc level, where it locks securely in place. Four stainless steel ratchet straps secure the dinghy or PWC using 6 tie down points incorporated in the SeaLift. This entire process of launching or stowing your tender/pwc is conveniently done in less than 18 seconds with the one touch wireless remote control.
2. What materials are used to build the SeaLift Hydraulic System?
The SeaLift is manufactured to the highest standards. Each SeaLift is custom designed by a naval engineer with over 35 years of experience. We use 100% stainless steel to better tolerate the harsh conditions of a salt water environment. Anti-fouling paint is used on the transom mounted assembly to deter barnacle and algae growth. Many other lifts do not use anti-fouling paint and are made of powder coated aluminum which will deteriorate much faster in salt or fresh water. Each SeaLift is tested and rated for lifting capabilities suited for your application.
3. Does the SeaLift have different lift capabilities for smaller applications?
The SeaLift System has a maximum lift capacity rated up to 1500 lbs. Boat size and individual application will determine which rated lifting capabilities you choose. SeaLift, Inc. will not increase capacity heavier than allowed by the manufacturer. No transom modifications are required for installation. Sealift has built in overload safety devices to prevent boat or lift damage.
4. Why is the the Cradle SeaLift considered the best value of all hydraulic lift Systems?
The convenience and simplicity of “one touch” wireless remote control operation allows easy lifting, stowing, and launching of your tender/pwc in less than 18 seconds. SeaLifts are manufactured to the highest quality standards and made of 100% stainless steel to better tolerate the harsh conditions of a salt water environment, not powder coated aluminum like other lifts. Our removable patent pending cradle and lock mechanism can be stored when not in use. SeaLift weighs only 250 lbs and was designed to keep the center of gravity over the swim platform. By keeping the weight forward there will be little change in your boats performance. Compared to other lifts, SeaLift is the leader in minimizing the reduction of performance by adding a tender/pwc lift to a boat. SeaLift has a capacity rating of up to 800 lbs, depending on your application. Installation is independent of your swim platform and no transom modifications are required. SeaLift is the most affordable hydraulic transom lift and is half the price of expensive platform lifts. Professional company certified installers and a comprehensive limited warranty make SeaLift the best value of all hydraulic lift systems on the market.
5. How do I choose the appropriate size tender/pwc for my boat?
Always keep the length of your tender/pwc at least 2 feet shorter than the width of your transom. For example, a new 40’ SeaRay Sundancer has a beam that is 13’2” at the widest point. However, at the stern, the swim platform is only 12’2”. So the ideal size of your tender should be 10’ for this boat. Weight is also an issue. The more weight you have at the stern, the longer time for your boat to plane. The SeaLift System weighs only 250 lbs. Keep your tender light and remember to add life jackets, gas tank, engine and battery when figuring total weight.
6. Will the additional weight on the stern reduce my boat’s performance?
Anytime you add weight to the transom of a boat you will affect boat performance. The trick is to minimize the lift weight and to keep the center of gravity forward. The SeaLift System is only 250 lbs and is made to keep the center of gravity forward over the swim platform. Our system will keep your tender/pwc untouched by acceleration or deceleration wakes and is less likely to be affected by following seas. SeaLift keeps your dingy or PWC high and dry. Compared to other lifts, SeaLift is the leader in minimizing the reduction of performance by adding a tender/pwc lift to a boat.
7. What if I need more reach to accommodate my large swim platform?
Every SeaLift is has a custom made dually integrated four-bar linkage system that has been measured to fit your individual boat’s configuration. We have a naval engineer with over 35 years of experience that will custom design the SeaLift to your application. Our designs can make adjustments in the linkage of up to 50” from the transom of the boat.
8. Will the SeaLift block the use of my swim platform?
No. About 1/3 of the tender/pwc beam is over the swim platform, which allows access to your platform while minimizing the affect of lift on performance. With the SeaLift System your swim platform remains uncluttered. Unlike tip-up lifts, a sizeable foot path is available to easily secure dock lines, acquire access to transom lockers to run power cords, or reach needed cleaning supplies.
9. Who completes the installation of the SeaLift Hydraulic System?
Once you decide which rating capacity meets your needs and your SeaLift is custom designed, then our professional company trained installers will integrate your SeaLift into the transom of your boat. Your SeaLift System will give you years of relaxing fun on the water.
