The search results provide a good amount of information for the Sundance 20.
Summary of findings:
- Designer: E. A. Brown (confirmed). No specific "design philosophy" for E. A. Brown found, but the boat is described as a "small sailboat designed by the maritime architect EA Brown in the early seventies". The builder article mentions a focus on "practical and accessible sailing vessels" for El Mar, which likely aligns with Brown's design for the Sundance 20.
- Builder: El Mar Boat Co. of Roseville, Michigan. Produced in the mid-1970s.
- Production: Started in 1972. End year not specified, but likely within El Mar's operating period (mid-1970s).
- Purpose: Described as a "Weekender" or suitable for "exploring shallow waters and protected anchorages" and "day sailing".
- Variations: A "Weekender" version has a longer coach roof and smaller cockpit. This is an important detail. Owners have discussed a "Sundance Weekender 20".
- Sailing Performance:
- Hull type: Monohull swing keel.
- Rig: Masthead Sloop.
- Described as a "light sailboat which is a high performer".
- "Nimble dinghy designed for responsive sailing and easy handling".
- "Quick hull" and "tracked really well" in club races, even when heeled.
- "Reasonably stable / stiff" but with "low righting capability if capsized". (This is a nuanced point for small boats, suggesting good initial stability but typical small boat characteristics if pushed too far).
- Accommodations/Layout:
- No direct interior diagrams or detailed descriptions were found in the initial search for "Sundance 20 interior layout." However, the mention of a "Weekender" version with a longer coach roof implies a more enclosed cabin for overnighting. The base model likely has a smaller cabin, typical of a 20-foot sailboat.
- No specific headroom information for the Sundance 20, but the Sundance 23 had 5.00 ft. Given the 20-foot size, standing headroom is unlikely.
- Owner's Perspectives:
- Owners express a "total lack of information about Sundance sailboats and the manufacturer".
- A Facebook group exists for "El Mar Boat Company Sailboats," indicating an active, albeit niche, owner community.
- Owners praise its "quick hull" and good tracking.
- Common issues mentioned: spreader re-riveting to the mast and general lack of available information.
Now I can proceed with writing the article based on these findings, adhering to all instructions.
