Lighting fixtures, locations, etc., shall meet all the requirements of South Carolina Department of Transportation (SCDOT) and the current NHTSB requirements for motor vehicle/trailer lighting. Secure the new wiring to the trailer structure at no more than 18-inch intervals, and at each fixture connection.

Furnish and install bunks with carpeting on the trailer. All bunks shall be a new, single, solid piece of lumber, not manufactured or composite wood created from several layers of lumber. The bunks shall be installed at an elevation that allows the hull of the vessel to bear zero contact with the trailer fenders, even during vessel movement. The vessel hull shall be in contact with each bunk over the entire length of the bunk. A piece of 3/8-inch thick synthetic material (UHMWPE, or approved equal) shall be installed on top of each bunk, over the entire length of each bunk and on the bow cross member and any location where the vessel may touch the trailer while loading. This synthetic material shall be the only material that comes in contact with the bottom of the vessel when it is on the trailer. All bunks and chocks shall be custom fitted to the hull of the vessel so the combined trailer and vessel height shall meet OTR guides and be under 13’ 6” tall on the trailer.

Furnish and install one (1) new drop leg tongue jack with a vertical crank (not horizontal).

Furnish and install a 3,600 pound (min.) capacity, 2-speed hand winch on the trailer with suitable size Samson Amsteel Blue synthetic rope and a suitable size stainless steel bow hook.

Fabricate side guides to position the boat hulls on the bunks. The side guide rails shall consist of two rails 1 port and 1 starboard spanning the length of the hull. The rails will be fabricated from a new solid single piece of lumber lined with carpet and capped with UHMWPE.

Furnish and install a bow stop that incorporates the bracket for the hand winch. A tongue mounted ladder to access the vessel at the bow shall be provided. Install a carpeted solid wood timber between the bow stop uprights to fit across the vessel’s push knees. Fabricate forward and aft braces on the bow stop as needed for support. Apply non- skid surface tape to ladder steps.
