I would contact CSC forum members "Finster" or "Wavelength" They both do this for a living
I would recommend you hang a couple of fenders off the gunwhales and tie it off amidships and the 2 lines from the transome and take your time. I think this hook-up might might be an easier method for a 4 hour trip.
Towing alongside allows the two boats to be maneuvered as one and is the preferred technique when approaching a dock or mooring or maneuvering in congested waters. Make the bow line (1) fast first, then maneuver the towing boat so that its bow angles in slightly toward the towed boat and its propeller(s) and rudder(s) are aft of the towed boat’s transom, rudder(s), or stern drive(s). This will give maximum maneuverability. In calm weather rig the stern line (2) next, followed by the tow strap or forward spring line (3) and the backing line (after spring line, 4). In wind, seas, or current, rig the tow strap and backing line before the stern line in order to get the tow underway quicker.
