I now have enough information to construct the article.
Summary of findings and how they address the plan:
- Builder Clarification: Confirmed Regatta 370 built by UK-based Westerly Marine Construction Ltd. 3, 4, 5, 9 in previous searches. This directly addresses the discrepancy and will be clearly stated in the introduction. The provided builder article on American Westerly Marine Inc. will not be used for details about the Regatta 370's construction, but the distinction of the name "Westerly" will be noted.
- Designer: Ed Dubois. His design philosophy for the Typhoon 37 (and thus Regatta 370) was for a "more performance-orientated boat" compared to earlier Westerlys.
- Production: 1994-1997, with 8 built 4 from from previous search results.
- Sail Area: Westerly-Wiki provides 361 sq ft for the main and 241 sq ft for a No. 1 jib, totaling 602 sq ft 9 from previous search results. This will be used for calculations.
- Performance Ratios (re-calculated with 602 sq ft):
- SA/Disp: 14.76 (implies moderately powered for cruising, not a light-air flyer).
- Ballast/Disp: 36.7% (good for stability).
- Disp/LWL: 226.3 (medium-heavy cruiser).
- Hull/Keel/Rudder: Fin keel, spade rudder. Shoal draft option available (from).
- Interior Layout: Designed by Ken Freivokh. Features a double berth in the forward cabin, marine WC in forward heads. Two aft cabins and a "spacious saloon", offering "two heads". The interior design was described as a "slight improvement in terms of cabin layout, but unpopular due to looks and execution". This is good detail to include.
- Owner's Perspectives: "Build quality was decent with no stand out issues" for the Typhoon 37, which shares the hull. The "unpopular" interior design is a recurring comment 6, 11 from previous searches, suggesting a potential weakness from owners. The Westerly Owners Association is mentioned as a resource, but no direct synthesizable reviews of common strengths/weaknesses specific to the Regatta 370 are easily extracted beyond the interior comments. I will include the information about the decent build quality and the mixed reception of the interior.
I have all the necessary information to proceed with article generation.
