What this video covers

Steve and Mike from Alliance Marine installed a custom stainless steel solar structure on the Lagoon 450 catamaran Some Tuesday.0:06 The structure features a double row of solar panels oriented longitudinally, making it the largest solar frame the fabricators have constructed for this class of catamaran.0:35 To install the heavy assembly, the crew utilized the boat's topping lift as a crane to hoist the structure from the dock onto the stern.0:46 Mike, a former tugboat captain, performed the welding on-site, using portable shielding gas to maintain an oxygen-free environment despite wind interference.1:56 Post-weld, the team used a Scotch-Brite wheel to remove heat-induced coloration and restore a mirror finish.2:21 The design incorporates one-inch, 120-wall stainless steel tubing to reinforce the existing davits, which now attach to the solar truss to distribute weight across the deck.2:37 This modification allows the boat to carry a larger dinghy and outboard motor.2:58
