IMM Quality Boat Lifts are measured by capacity in pounds, rather than the length of the boat. Once you’ve calculated the fully-loaded wet weight of your boat, you can figure out a boat lift capacity that will safely handle your boat. You should consider what size boat you may be upgrading to over the next few years before purchasing your lift. If you’re not sure about the weight of your boat, please look at our lift selector on the contact page, or contact us directly at 1-800-545-5603. IMM Quality Boat Lifts for sale can accommodate most any boat, from a PWC to the largest yacht!
