50' Alden Challenger 50

Designed by renowned naval architect John G. Alden and built by Challenger Yachts in California, the Challenger 50 combines heavy-displacement construction, a full keel, protected pilothouse, generous interior volume, and exceptional long-range tankage.

FootSeas size and layout make her particularly attractive for sailors who want a true cruising home rather than simply a larger coastal sailboat. The protected pilothouse and center cockpit provide excellent security underway, while the ketch rig offers flexible sail combinations for offshore passagemaking.

Below decks, her generous beam creates a spacious traditional interior with two cabins, two heads, a large galley, substantial storage, air conditioning, and sleeping accommodations for extended family or guests.
