This Multinautic R-2500 ramp kit allows you to build your own ramp for small boats or personal water craft up to 2500 lbs. Its higher quality rollers allow for an easier lift and will smoothly operate with heavy PWC. Securely beach your boat or PWC on the shore line and prevent any damages to hull or turbine due to sand or rock abrasion. Being secured on the ramp, your PWC or small craft will never rub on, or underneath the dock due to wave action. You can also remove the drain plug of your fishing boat in order to make sure it will not fill with water and sink. Peace of mind for a very small investment.
