Accommodations
Low
The hull liner-to-hull bond on Catalina 380s can develop voids and separations over time, leading to creaking and flexing of the interior furniture and headliner in a seaway. This is a known Catalina construction characteristic and can be difficult to fully repair.
Electrical
Medium
Early Catalina 380s left the factory with undersized battery banks and minimal DC wiring for the equipment buyers typically add. Wiring additions are often done informally by owners; inspect the DC panel and bilge wiring closely for amateur splices and overloaded circuits.
1997–2001 models
Engine
Medium
The 380 was typically fitted with a Universal M35B or M40B diesel. The raw water impeller housing and heat exchanger on these engines are prone to scaling and early failure in salt water use; verify full service history and check for overheating incidents.
Low
The engine access on the 380, via a companionway drop-board and cockpit locker, is awkward and limits routine maintenance visibility. Neglected engine mounts, stuffing boxes, and transmission fluid levels are common findings due to difficult access.
Hull/Deck
Medium
The deck-to-hull joint on the Catalina 380 uses an inward-turning flange bonded and through-bolted, but the toerail screws along this joint are prone to leaking, allowing water intrusion into the balsa-cored deck sections. Check for soft spots along the toerail, especially at the bow and stern quarters.
High
The balsa core used in the deck is vulnerable to moisture intrusion around chainplate and stanchion base fittings. Delamination and rot in the balsa core beneath stanchion bases is a well-documented issue on this model; probe all bases carefully during survey.
Medium
The portlight frames (both fixed and opening) on early 380s are known to leak at the frame-to-deck seal, leading to water intrusion into the cabin liner and potential core saturation in the coachroof.
1997–2002 models
Keel
High
The fin keel on the 380 is attached with keel bolts that pass through a relatively shallow sump. Keel bolt corrosion and weeping at the keel-to-hull joint is a known concern; inspect the bilge sump carefully for rust staining, and verify all keel bolts are tight with no signs of movement.
Rigging
High
The chainplate knees on the Catalina 380 are glassed to the hull liner rather than the hull itself on some production runs. This arrangement can allow flexing and eventual failure of the glass tabbing; inspect for cracking or separation at the chainplate-to-liner interface.
Medium
The aluminum mast step casting on deck-stepped masts is prone to cracking and corrosion, particularly where water pools around the base. Inspect the mast step and surrounding deck core for softness and structural integrity.
