The S2 8.5 entered production in 1980, continuing until 1983. It was designed by Arthur Edmunds, a naval architect who significantly contributed to S2 Yachts' early sailboat designs between 1974 and 1980. Edmunds crafted the 8.5 as a cruiser, reflecting a design philosophy that aimed for sound principles and reliable performance. S2 Yachts, founded by Leon Slikkers, was known for its meticulous craftsmanship, leveraging extensive fiberglass experience and innovative construction techniques, such as incorporating fabric into their manufacturing processes. The hulls were typically crafted in a climate-controlled environment, ensuring consistent high quality.
During its production, the S2 8.5 saw minor variations, including being referred to as the 8.5A. A few early models were fitted with a BMW diesel engine instead of the more common Yanmar. Additionally, a shoal draft option of 3.92 feet was available, complementing the standard 4.5-foot maximum draft. The S2 8.5 was later succeeded by the S2 8.6, which continued production until S2 Yachts ceased sailboat manufacturing in 1986.
Sailing Performance and Handling
The S2 8.5, with its fin keel and spade rudder, offers a balance of stability and responsiveness. With a calculated Sail Area to Displacement ratio of approximately 15.97, the S2 8.5 is classified as having moderate light-air performance, suggesting it performs capably but might not excel in very light conditions without significant sail area. Its Ballast to Displacement ratio, around 0.39, indicates a good level of stiffness, allowing the boat to stand up to a decent breeze and maintain a more comfortable motion in a seaway. The Displacement to Length ratio, approximately 298, places it in the heavier category of cruising boats for its length, contributing to its solid feel and comfortable ride.
Anecdotal evidence from owners often praises the S2 8.5's sailing prowess, with some noting its ability to outperform comparable boats of its era. It is generally regarded as having good sailing characteristics and balance, making it a satisfying boat to sail across various conditions.
Accommodations and Layout
The interior of the S2 8.5 is a testament to S2 Yachts' reputation for quality finishing and thoughtful design. Owners consistently praise the interior layout and overall finish of S2 sailboats. The design avoids exposed raw fiberglass, contributing to a more refined and comfortable living space below deck.
The S2 8.5 offers a generous maximum headroom of 6.0 feet, which is considerable for a boat of its size, enhancing comfort when moving about the cabin. While specific interior configurations could vary, the boat typically features a V-berth forward, a head, and a main salon with settees and a table. The galley and navigation station are usually situated towards the companionway. The shrouds are notably set well inboard, which not only aids sail trim but also creates wider, more easily navigable side decks. Storage is generally well-integrated, and ventilation is typically achieved through opening ports and hatches, common for boats of this vintage. Some S2 8.5 models were produced with "several interior/companionway arrangements," offering minor variations in the cabin's configuration.
Owner's Perspectives
Owners of the S2 8.5 consistently highlight the boat's solid construction and overall build quality as significant strengths. The interior design and finishing are frequently lauded, creating a comfortable and appealing living space. Many describe the S2 8.5 as a "great sailboat" that offers enjoyable sailing characteristics. Its robust build quality has allowed many of these vessels to remain desirable and capable cruisers decades after their production.
While generally well-regarded, like any older vessel, potential owners should be aware of common maintenance issues. One instance noted a "wet like a sponge" cockpit sole, suggesting that moisture intrusion and core degradation in deck structures can occur and should be inspected on older models. General maintenance, such as steering system upkeep, is also a typical consideration for a boat of this age. Despite these potential age-related concerns, the collective viewpoint of owners reinforces the S2 8.5's reputation as a strong, capable, and comfortable cruising sailboat.
