What this video covers

Installing a marine air conditioning system requires significant structural modifications when the vessel was not originally designed for the equipment. To accommodate a 9,000 BTU Marine Breeze variable-speed unit in the aft berth, the owner cuts a recessed well into the existing bed platform to gain necessary vertical clearance.▶ 6:49 The installation involves bonding a new fiberglass floor section to the underside of the berth, creating a custom air-deflector mold from a cockpit seat to smooth airflow through a 90-degree duct transition, and glassing the assembly into place.▶ 20:12 The owner selects a 16,000 BTU unit for the salon and a 9,000 BTU unit for the berth, opting for variable-speed compressors to improve energy efficiency and reduce noise by eliminating the constant on-off cycling of traditional units.▶ 3:01 These units will eventually integrate with the boat's 48-volt hybrid power system.▶ 5:27 Proper planning for ducting and wire runs remains critical, as the installation requires repurposing limited space near the water source and electrical runs.▶ 6:18
