A Word From The Owners:

"We purchased this boat in Panama in 2022 and immediately started upgrading this solid foundation of a boat. All electronics, watermaker, trampoline, and dinghy have all been upgraded to the newest equipment. We spent two years cruising the Caribbean and then headed back to Panama where we crossed the Panama Canal in early 2025 and crossed to French Polynesia, Samoa and eventually Fiji. This boat was never chartered and I'm the 2nd owner. Previously the boat was used in Panama for only a few months a year and had a full-time employee cleaning and taking care of the boat during off season. This boat is fast with a solid hull. You will be sailing when all others are motoring as she excels in light air. Each model of this boat was made to owner specifications with certain options, this one most notably has skegs in front of sail drives to protect sail drives and rudders. We have been sailing with two children, now teenagers that are now preparing for their college years. "
