About the Seaward 26Rk

Designed for sailors who want a capable and comfortable small cruiser, the Seaward 26Rk is a compact sailboat that reflects the practical philosophy of Seaward Boats, a British builder known for producing versatile and well-crafted vessels suited to coastal and estuary sailing. The "Rk" designation suggests a lifting or retractable keel configuration, a hallmark of Seaward's approach to designing boats that can explore shallow-water anchorages and dry out on tidal flats with ease — a particularly valuable feature for sailing along the UK's varied coastline. This adaptability makes the 26Rk an appealing choice for weekend cruisers and liveaboard adventurers who prioritize flexibility over raw offshore performance. Seaward boats have generally earned a reputation for solid construction, thoughtful interior layouts, and genuine sea-keeping ability despite their modest size. Buyers drawn to this model are typically looking for a trailerable or easily managed cruiser that doesn't sacrifice comfort or safety in the pursuit of accessibility. For those researching a first cruising boat or a manageable second vessel, the Seaward 26Rk warrants serious consideration.

About this estimate
  • Prices are based on recent asking prices from public listings — not actual sale prices, which are typically lower.
  • Condition is not factored in. A well-maintained boat with new sails and engine can be worth significantly more than a project boat of the same model.
  • Location affects price. Boats in landlocked states or areas with fewer buyers often sell for less than those on the coast.
  • Year of manufacture is not filtered. Older examples of this model will generally be priced lower than newer ones.
  • Included equipment varies widely. A boat with a full suite of electronics, dodger, and new standing rigging may command a large premium.
  • Outliers are automatically excluded using statistical filtering to improve accuracy, but some bad data may remain.
