About the Ericson 33 Sailboat

Designed by renowned naval architect Ron Holland, this 33-footer represents Ericson Yachts' venture into performance-oriented cruising during the early 1980s. With only 28 hulls built between 1981 and 1984, the Ericson 33 remains a relatively rare find that combines Holland's racing pedigree with practical cruising capabilities. The boat's modern fin keel and spade rudder configuration delivers responsive handling and solid upwind performance, while the fractional sloop rig provides excellent sail control and balance. At 9,500 pounds displacement with 3,950 pounds of ballast, she offers a reassuring feel in moderate conditions without being overly heavy. The SA/Displacement ratio of 20.51 indicates spirited performance in light to moderate winds. Built during Ericson's quality-focused period, these boats feature solid fiberglass construction and thoughtful interior layouts that maximize the 33-foot length. The low Comfort ratio of 20.47 suggests a boat better suited to coastal cruising and weekend sailing rather than extended offshore passages, though the moderate Capsize screening value of 2.11 indicates reasonable stability for venturing beyond protected waters. Holland's design expertise shines through in the boat's balanced feel and predictable handling characteristics, making it an appealing choice for sailors seeking performance without sacrificing cruising comfort.

High
The fin keel attachment on this hull uses a relatively narrow keel sump; keel bolt corrosion and weeping at the keel-to-hull joint are commonly reported. The hull-to-keel joint should be carefully inspected for cracking or working, which can indicate loose or corroded keel bolts.
High
Chainplate backing plates are known to be undersized on some Ericson hulls of this period, and the chainplates themselves pass through the deck in a manner prone to leaking. Leaks here often lead to hidden rot in any wood blocking and saturation of nearby balsa core.
High
The internal chainplate arrangement routes shroud loads to tabbed-in bulkheads; the tabbing between the bulkhead and hull liner can delaminate over time, especially if chainplate leaks have introduced moisture. Inspect the tabbing at the main bulkhead carefully.
