I have a question regarding tug wakeboard boats

I have a question regarding tug wakeboard boats to shore with tide differences of 2 meters. We often leave the boats in the water (mixture of fresh and salt water), and tug to shore once a week for maintenances, but the sofa with custom accelerator often gets moldy and/or malfunctions. We are currently using a dock that were meant for bigger sail boats, so the tracks/slopes are not as steep, and fill with mud during low/dry tide. Our boats docks about 6 to 7 meters away from shore. Any suggestions on how we can tug boat to shore onto the trailer daily, even in low/dry tide? Need help!

If I'm understanding what your trying to do, you need a winch. they come in a bunch of sizes and power supply configurations, including manual like the one on your bow strap. Sailboaters use them to launch and retrieve.
