Accommodations
Medium
The original plywood interior joinery used by Pearson is susceptible to delamination and rot from chronic low-level leaks through the deck. Inspect all plywood cabinetry, bunk flats, and the area beneath the settees for softness or delamination.
Engine
Medium
Early Pearson 30s were fitted with the Atomic 4 gasoline engine, which has well-documented carburetor, fuel pump, and ignition issues. Many have been replaced with small diesel conversions; confirm what engine is installed and whether the conversion was done properly with correct exhaust and fuel systems.

Hull/Deck
High
The balsa-cored deck is prone to water intrusion around deck hardware, chainplates, and stanchion bases. Once wet, the balsa core rots and delamination spreads, often invisibly beneath the fiberglass skins. Tap testing the entire deck is essential.
High
Chainplate locations on the Pearson 30 are known to leak where the chainplates pass through the deck. The resulting water intrusion accelerates balsa core rot in that area and can compromise the structural integrity of the chainplate attachment.
Medium
The deck-to-hull joint on Pearson 30s uses an inward-turning flange with a rubber gasket and through-bolts. This joint is known to open up over time, allowing water intrusion into the hull-deck connection. Inspect the toerail and joint carefully for separation or sealant failure.
Medium
Stanchion bases on the Pearson 30 are bolted through the cored deck without adequate backing plates in many examples, leading to local core compression, cracking, and water intrusion into the balsa. Check every stanchion base for movement and soft deck beneath.
Keel
High
The fin keel attachment uses keel bolts that are subject to corrosion in the bilge area. The bilge sump on these boats tends to hold water, accelerating bolt corrosion. Inspection of keel bolt condition and any movement or weeping at the keel-to-hull joint is critical.
Rigging
Medium
The aluminum mast on early Pearson 30s is deck-stepped, and the mast partners area in the cored deck is a common site of compression damage and water intrusion into the balsa core. Inspect for softness and delamination directly around the mast base.
