The searches provided good information for all sections.
Introduction: I have the designer (Bruce Kelly), builder (Endeavour Yacht Corporation), and production years (1983-1987). I can synthesize its purpose as a cruising yacht with good performance.
History and Design:
- Production run: 1983-1987. Around 300 units built.
- Designer's philosophy: Bruce Kelley believed a cruising yacht should have "at best the performance potential of a racing boat of the same size."
- Builder's ethos: The builder article states that the 1980s saw Endeavour respond to pressure for "more performance-oriented designs and updated construction methods." The Endeavour 35 was designed by Bruce Kelly as part of this push. Construction involved Klegecell closed-cell polyvinyl foam coring and a "multi-axial steel reinforced 'force grid' bonded to the hull for stiffness" in this era. The boat was open molded and hand-laid fiberglass.
- Variations: No significant MKI/MKII variations found, but the builder article mentions a general evolution in construction during this period, including the use of Klegecell.
Sailing Performance and Handling:
- Ratios are calculated: SA/D ~19.43, B/D ~0.425, D/L ~230.42.
- Anecdotal handling: "most owners give good overall performance marks." "pretty decent performance for a cruiser especially considering the <5' draft."
Accommodations and Layout:
- Search results provide images and descriptions of interior layouts.
- It typically features a V-berth, head, salon, galley, and quarter berths.
- "generous use of teak and teak plywood interior joiner work". "excellent headroom and good sized interior". "teak cabinet work is exceptional".
Owner's Perspectives:
- Strengths: Owners praise overall performance, good info available on owner forums.
- Weaknesses/Common problems: "butt end of the mast and the mild steel mast step are also problem areas that must be inspected closely." "blistering problems about ten years ago" (from a 1984 boat review). Some mention of "problems which are fairly common with bolt on keels" in a forum context, though not specifically tied to the E35 in that snippet. "hull issues were too big of an unknown" on a specific boat that had "flooded over the cabin sole". These seem to be more individual boat issues rather than widespread design flaws, except for the mast step/mast butt.
I have enough information to construct the article.
