Used Comet 910 Plus Sailboats for Sale

I have found more specific information.

• Designer: Jean Marie Finot (Groupe Finot). Also mentioned as Finot / vd Stadt, linking back to the original Comet 910 collaboration. I'll prioritize Finot as the primary designer for the 910 Plus.
• Sail Area (Total): 51mq (549 sq ft). This is crucial for performance ratios.
• Interior Details: "more spacy than 62% of all other designs". "abitabilità" (habitability/liveability) is a strong point. One source mentions "a slightly more spacy hull design". Another mentions the "Plus" version has "a slightly shorter cockpit to create fixed galley and chart table". This suggests improved interior functionality compared to the standard 910. Headroom is explicitly mentioned as 0 ft in one source, which is highly improbable and likely an error or placeholder in a database. Given the "abitabilità" comments, it's safe to assume reasonable headroom for a 30ft boat, but I don't have a specific measurement.
• Handling: Described as "reasonably stable / stiff and has a good righting capability if capsized" and "best suited as a coastal cruiser". Also referred to as a "Cabinato per Crociera" (Cruising Cabin Yacht). The original Comet 910 was "solid and fast".

Now I have enough information to construct the article. I will use the 51mq (549 sq ft) sail area for the SA/D calculation.

Let's re-calculate the ratios with the confirmed sail area:

• displacement_lbs: 8157
• lwl_ft: 23.29
• ballast_lbs: 2646
• sail_area_total_calc_sqft: 549 (from 51mq)

Ratios:

1. Displacement to Length (D/L):
   • Displacement in long tons = 8157 lbs / 2240 lbs/ton = 3.6415 long tons
   • (0.01 * LWL in feet)^3 = (0.01 * 23.29)^3 = (0.2329)^3 = 0.01264
   • D/L = 3.6415 / 0.01264 = 288.1 (This falls into the moderate to heavy cruiser category, often associated with a comfortable motion.)
2. Ballast to Displacement (B/D):
   • B/D = 2646 lbs / 8157 lbs = 0.324 (This indicates moderate stiffness, capable of standing up to a reasonable amount of wind.)
3. Sail Area to Displacement (SA/D):
   • Displacement in cubic feet = 8157 lbs / 64 lbs/cu ft = 127.45 cu ft
   • (Displacement in cubic feet)^(2/3) = (127.45)^(2/3) = 25.59
   • SA/D = 549 sq ft / 25.59 = 21.45 (A high SA/D ratio, suggesting good light-air performance and a more performance-oriented cruiser.)

These ratios will be interpreted qualitatively.

The "Comet 910 Plus is a version postuma (later version) of the std. (standard) Comet 910" and "Has a slightly shorter cockpit to create fixed galley and chart table". This is good for the History/Design and Accommodations sections.

I have enough information to write the article.
