The searches provided a lot of good information:

  • Designer: Stan Huntingford (Canadian maritime architect).
  • Design Philosophy/Goals: Built as a "true bluewater cruiser designed for ocean cruising" with objectives of "simplicity, seaworthiness and beauty". Heavy displacement, double-ended cutter rig, full keel, tiller steered (often). Designed for serious cruising, coastal hopping or ocean crossings, offering reassuring stability. Based on NW coast fishing boats.
  • Production Years: says production_start_year: 1975. Search results show models from 1976 and 1978. production_end_year is not explicitly stated, but "less than 100 boats have been built". Given the context, it likely ended in the late 70s or early 80s, but without a concrete end year, I will state it ran for some years.
  • Variations: Sometimes known as the Slocum 37. "Slocum 37. Similar but with a wheel and integrated..." suggests variations, but no distinct MkI/MkII.
  • Sailing Characteristics: "heavy displacement, double-ended cutter rig sailboat built for ocean cruising". "Offers reassuring stability in all conditions". "Long keel provide a better directional stability". "Good sailors to boot (surprisingly so given their displacement and full keel)". "Cutter rig allows for a balanced sail plan in all conditions and a compact rig with smaller sails that are easy to handle". Will "move in light airs".
  • Interior Layout: "Spacious cabin boasts a beautiful solid teak interior". "Stunning interior and finished woodwork throughout". "More storage than 90% of 37 foot boats". "Slightly more spacy hull design". No detailed layout diagrams found directly, but descriptions of "solid teak interior" and "finished woodwork" are good.
  • Owner's Perspectives/Common Issues:
    • Strengths: "bulletproof, heavy displacement, full keeled, canoe stern-ed, tiller steered, cutter rigged blue water sailboat". "Very well constructed, well designed, and good sailors". "Solid construction and comfortable motion in a seaway" (implied by design for offshore cruising). Ample storage.
    • Weaknesses/Common Issues: "Two biggest challenges... teak deck, and dealing with the black iron diesel tanks". "General re-sealing of deck hardware is a must". "Water ingress being common through" deck hardware. "Nothing really comes to mind that wouldn't be common for all older boats (wiring, plumbing, decks, rigging, etc)". Electrical panel issues mentioned but not common. Not known for blistering.

Now I have enough information to construct the article following the given structure.

Calculated Ratios Recap:

  • Sail Area to Displacement (SA/D): ~13.08
  • Ballast to Displacement (B/D): ~0.434
  • Displacement to Length (D/L): ~360.9

These ratios indicate a heavy displacement, stable, and stiff boat, leaning towards comfortable cruising rather than light-air performance. The SA/D is on the lower side, suggesting it might need a breeze to get going. The B/D is high, indicating good stability. The D/L is very high, confirming a heavy, full-keel cruiser.
