Gib'Sea 402 Buyer's Guide
Shopping the brokerage market for a used Gib'Sea 402 means choosing between owner-oriented three-cabin layouts and ex-charter four-cabin versions, both of which are well represented, with former charter boats a common sight. Built by Gibert Marine between 1987 and 1991 to Joubert-Nivelt's late-1980s design, fewer than 100 were completed, so each purchase is a study of an individual hull's history rather than a commodity model.
Layouts on the Used Market
The two dominant layouts diverge in privacy and charter pedigree. The three-cabin owner configuration trades a fourth stateroom for more saloon or storage volume, while the four-cabin ex-charter boats prioritize guest separation and show up frequently in listings. A buyer should decide early whether charter wear — heavier cycle counts on systems and surfaces — is acceptable for the lower complexity of the owner layout.
Equipment and Common Upgrades
Well-equipped examples commonly carry solar, an inverter, and lithium batteries, forming a power cluster that supports anchoring without a generator. Climate and navigation clusters are also usual: air conditioning, a watermaker, radar, autopilot, and chartplotter appear on many boats, meaning a buyer can expect push-button navigation and extended independent cruising without immediate upgrades. Canvas typically includes bimini, dodger, and cockpit shower, with a life raft often part of the safety inventory.
What to Inspect
The keel is iron on both draft options, so survey for corrosion at the hull-keel joint and coating breakdown on the iron itself. The deep-keel variant draws about 6.56 to 6.86 feet and the shallow about 4.92 to 5.22 feet depending on load, and a buyer should verify the actual fitted keel against the marina depths she will use. With a low production count, no two boats will present identical upgrade histories, so document each system's age.
Availability and Buyer's Takeaway
Typical markets are France, the United Kingdom, the United States, Spain, and the Netherlands. For a buyer, the short checklist is: confirm keel type and iron condition, verify the layout matches intended use, and assess the lithium-solar-inverter cluster as the baseline for modern cruising. The 402 rewards a careful survey with a beamy, limited-production Joubert-Nivelt cruiser in either owner or ex-charter form.
