The search results provide a lot of useful information.
Key findings from search results:
- Designer: Gary Mull for the Newport 30-3 (and other Newport models).
- Design Philosophy (Newport 30-3 specific): The Newport 30 MkIII is described as "more cruising oriented" and "more cruise friendly" compared to earlier Marks. It has a "big boat feel" for a coastal cruiser. Gary Mull was known for creating popular fiberglass sailboats and many of his designs were performance-oriented cruisers.
- Variations: The notes already mention MkI and MkII, and the current model is the MkIII, distinguishing it as more cruising oriented. Shoal draft option of 4.00' is mentioned. A tall rig option is also described in the notes.
- Sailing Performance and Handling (Anecdotal): "sails great too!", "decent boat but nothing amazing", "nice coastal cruiser with a big boat feel". Owners appreciate the roller furling option and lines led to the cockpit for ease of handling. The boat can handle various conditions well.
- Accommodations and Layout: Sleeps five in a "large and comfortable interior." Mention of an "aft cockpit with companionway center forward". The interior layout involves an engine "a little offset from centerline" in the cabin. "GRP interior liner" is mentioned, which implies some customization challenges. The boat has a 70-gallon water capacity.
- Owner's Perspectives:
- Strengths: Solid construction, comfortable motion, good coastal cruiser, sails well.
- Weaknesses/Common Issues: Some issues with blisters, but generally easy to fix. Concerns about exposed keel bolts or brown water in the bilge are mentioned, suggesting potential inspection points. The original engine (Universal-Atomic M018) might be considered slightly underpowered by some owners. Structural problems or bulkhead replacement can be expensive.
Now I have enough information to construct the article following the specified structure.
Calculated Ratios Recap:
- SA/D: 16.29 (Moderate performance)
- B/D: 0.306 (Moderate stability, less stiff)
- D/L: 203.99 (Moderately light, performance-oriented cruiser for its size)
These ratios, combined with the "more cruising oriented" description, suggest a balanced design that leans towards comfortable cruising with decent, but not exhilarating, performance.
