The 4000 lbs vertical lift is the most common style lake lift. This model is for boats only under 9ft wide - allowing for the lift to work in narrow spaces. With the ShoreMaster vertical lift, you only need 18 inches of water clearance and most models have a lifting height of 66 inches, the highest in the industry. The double V-side design allows for easy access to your boat from either side of the lift. This type of lift works with many different lake restrictions and requirements.
