What the fleet has seen

The Jeanneau Sun Fizz 40, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Jeanneau Sun Fizz 40 is a 12.3-meter masthead sloop designed by Philippe Briand and built by Jeanneau from 1980 to 1984, also sold in the US as the O'Day 39 and later O'Day 40. Aboard *Namasté*, a 1981 model, the crew installed a stainless steel arch in Tunisia for three 175-watt solar panels, two of which charge a 400Ah house battery bank, and the third powers the windlass and bow thruster.0:44 Rainwater collection gutters feed into 45 liters of storage. The cockpit features custom canvas cagnards and a Bimini, while the stern has a modified swim platform with an integrated shower and davits for a 2.50-meter semi-rigid dinghy with a 6hp Yamaha outboard. Interior renovations include replacing original pilot berths with storage lockers, painting the cabin white, and converting the chart table into a desk.8:58 The galley features a modified sink and a Perkins 4108 engine.7:59 The owners removed bulkheads in the forward cabin to create a larger living space and converted a rear cabin into a workshop.8:13 Navigation relies on electronic charts and a wheel-mounted autopilot.10:02 Aboard *Namasté*, the crew struggled with autopilot failure during a 140-nautical-mile passage from Cayo Largo, Cuba, to the Cayman Islands, necessitating a repair with scrap teak and Teflon bushings.11:09 After five months away, the crew returned to *Namasté* in Guatemala to find it heavily fouled, prompting an interior refit that included rebuilding the forward cabin floor, replacing the galley countertop, and installing a new autopilot with custom wiring and a protective box.0:42
