{"id":815,"count":5,"description":"Jefferson is represented in the used market by a family of motor yacht designs commonly referred to as Marquessa and Sundeck models, with examples in the available listings dating from the late 1980s through 2000. These yachts are double-deck motor yachts and sundeck\/cockpit motoryachts that emphasize interior volume and traditional layout arrangements found on long-range cruising vessels.\n\nConstruction details in the listings note that several Jeffersons were built in Taiwan under American supervision, and that high-end, hand-rubbed teak joinery is a recurring feature. Hull forms described include a low-deadrise hull with a shallow keel on the Sundeck models, a configuration that typically delivers a comfortable and stable ride in moderate conditions and is a common characteristic cited for extended-cruise use.\n\nLayout variations reflect the marque\u2019s focus on liveaboard comfort and extended cruising. Typical arrangements include a flybridge, aft deck and cockpit, full-beam master staterooms, multiple guest staterooms and heads with enclosed showers, and onboard office spaces that can convert to additional sleeping accommodations. The Extended Deckhouse (EDH) variant is explicitly noted for widening the salon by narrowing side decks, producing a near full\u2011width main saloon and significantly increased interior living area relative to non\u2011EDH versions.\n\nDocumentation and maintenance history appear to be emphasized in the listings. One 2000 60' Marquessa was repainted in 2022 and completed a 4,000\u2011hour engine service interval in 2025, with maintenance records and oil analysis reports available. Practical considerations for cruising are also detailed: the same 60' example reported a 16'4\" air draft above the waterline, a datum used to assess transits such as the Great Loop.\n\nAcross the cited examples the Jefferson name is associated with robust construction, teak interiors and layouts that prioritize liveability over lightweight, performance\u2011oriented design. These traits are consistent with vessels marketed for extended cruising or use as full\u2011time liveaboards.","link":"https:\/\/www.yachtsite.com\/brand\/jefferson\/","name":"Jefferson","slug":"jefferson","taxonomy":"brand","parent":0,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/www.yachtsite.com\/wp-json\/wp\/v2\/brand\/815","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yachtsite.com\/wp-json\/wp\/v2\/brand"}],"about":[{"href":"https:\/\/www.yachtsite.com\/wp-json\/wp\/v2\/taxonomies\/brand"}],"wp:post_type":[{"href":"https:\/\/www.yachtsite.com\/wp-json\/wp\/v2\/reference?brand=815"},{"href":"https:\/\/www.yachtsite.com\/wp-json\/wp\/v2\/yachts-for-sale?brand=815"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
