Nelson Marek 41 IOR Fractional Rig

Description

The Nelson Marek 41 (often called Nelson/Marek 41 or NM 41, with variants like Serendipity 41 or Geraghty 41) is a high-performance IOR (International Offshore Rule) racing sailboat from the early 1980s, designed by the San Diego-based firm Nelson/Marek Yacht Design (Bruce Nelson and Bruce Marek). It was typically custom or semi-custom built (e.g., by Geraghty Marine in San Diego around 1981–1982, with some closely related boats like the Schock 41 from 1983 noted as nearly identical in concept), emphasizing lightweight composite/fiberglass construction, fin keel with spade rudder for speed and agility, and competitive IOR 2-Ton rating (around 32.0 IOR) for offshore and buoy racing—proven in events like Mackinac races and class wins. Production was limited to a small number of hulls (likely low dozens across variants, based on rarity and historical context; no mass-production series), featuring a masthead sloop rig (with fractional options in some configurations), minimal cruising accommodations (basic berths, galley, head for crew/racing use), and a reputation for strong performance in varied conditions, though more race-focused than comfortable bluewater cruiser (contrasting the classic Swans or Najads in your earlier queries).
