Used Jpk 40 Sailboats for Sale

The search results primarily discuss the JPK Nomad 40 (a motorboat) and the JPK 39FC, which is a fast cruiser. There isn't a direct article or review specifically for the "JPK 40" as a sailboat, which the provided describes. The JPK 40 in the is a monohull, with a deep bulb keel and twin rudders, and a fractional sloop rig. The production years are 2007-2021. This indicates it's likely a racing cruiser, given JPK's reputation, and the high performance ratios calculated.

The search results for "JPK 40" mostly redirect to or mention the JPK 39FC or JPK Nomad 40, suggesting "JPK 40" might not be a widely used model name for a specific sailboat, or it's an older model that has been superseded by names like JPK 39FC or JPK 45 in common discourse. However, the explicitly states "make": "JPK", "model": "40", "name": "Jpk 40".

I need to be careful not to conflate the "JPK 40" (from the) with the "JPK Nomad 40" (motorboat) or the "JPK 39FC" (a different sailboat model, though similar in size).

Refined Plan:

• Introduction: Stick to the and builder article. Mention JPK 40 as a performance-oriented sailboat by JPK Composites and designer Jacques Valer.
• History and Design: Use production_start_year (2007) and production_end_year (2021). Emphasize JPK's design philosophy of balancing performance and seaworthiness for offshore racing and fast cruising, and their infusion construction technique, drawing from the builder article. I could not find specific design philosophy for the JPK 40 model itself, so I will generalize from JPK's overall philosophy. I also did not find information on variations for this specific JPK 40 model.
• Sailing Performance and Handling: Use the calculated ratios (SA/Disp ~42.56, Bal/Disp ~0.445, Disp/L ~70.88). Highlight these numbers' implications. Mention the water ballast. The search results indirectly support JPK's general performance characteristics (high sailing potential, excels in offshore racing).
• Accommodations and Layout: This will be challenging. Since there's no specific "JPK 40 interior layout" review for this model in the search, I need to state that information is limited. I can refer to JPK's general approach to interiors in their performance cruisers (balancing comfort with racing needs), drawing from the JPK 39FC (a "sporty 40 cruiser") or JPK 45 reviews which mention balancing performance with interior comfort. I will avoid fabricating details.
• Owner's Perspectives: Since specific owner reviews for "JPK 40" are not found (only for other models like JPK 39FC), I will likely omit this section or state that information for this specific model is not readily available, as per the instructions "If you cannot find information on a specific topic (like owner reviews), omit that section."

Let's re-run a targeted search to see if "JPK 40 sailboat review" or "JPK 40 specifications" yields more specific results, as the initial search was broader. I need to be sure about the "JPK 40" as a distinct sailboat model before concluding there's no info. The describes a sailboat, with sail area, ballast, keel, rudder, etc. The search results for "JPK 40" mainly show "JPK Nomad 40" (motorboat) or "JPK 39FC." There is one result, sailboatdata.com, for "JPK 40" which confirms it as a sailboat with a fin w/bulb keel & dual rudders. This confirms the existence of the specific sailboat model. I will use this as a reference point.
