Assuming no other water craft is involved in the configuration, then the Dock Edge Stand-Off Flip-Up Polyethylene Roto Molded 4-Step Dock Ladder, SKU: CW64104 will work. This tough and durable, roto-molded Dock Edge Stand-Off Flip-Up ladder swings up and out of the way, locking in place when not in use. The Stand Off roto-molded ladder extends into the water at a 60 degree angle to make getting out of the water easier.
However, assuming other water craft is involved, then the angle of inclination of the ladder from the deck of your boat to the floating dock will depend on sea conditions; such as tide, wind and current. Based on these variables the answer would be No. You would have to custom build a ladder with a sensor which would be expensive and create other expenses.
1. Should you decide to use a ladder, secure your boat. Seek professional assistance to measure the distance from the deck of your boat to the floating dock when it is on seabed (mud). This would give you an idea of the vertical length of a required ladder. This distance should be greater than the distance between the deck and top of the floating dock at high tide. You may need to account for the distance between the top of the floating dock and mud at low tide if you should have to walk from the floating dock into the mud at this tide.
2. Secure buoyant fenders of at least 12” in diameter on the side of the floating dock closest to the boat to prevent direct contact between the boat and the floating dock which could crush the ladder should it somehow get pushed between the two objects.
3. You should not attempt to do this work on your own. Contact the floating dock installer or some other licensed professional for assistance and to determine if this is the most effective solution.
