2011 J Boats 37' "Obsidian"

OBSIDIAN is a highly developed and exceptionally well-equipped J/111 with extensive recent upgrades, a professionally prepared racing bottom, carbon rig, updated NKE electronics and an outstanding inventory of recent Ullman sails.

Hull #5 of the J/111 class, OBSIDIAN has been continually maintained and optimized for competitive racing. Recent investment includes new stainless rod standing rigging and Spectra backstay in 2025, NKE instrumentation in 2024, B&G Vulcan 9 chartplotter in 2026, Jefa lower rudder bearing and gaiter in 2024, Gori folding racing propeller in 2025, and an extensive Ullman Carbon FiberPath sail inventory.

Her keel has been templated and the bottom long-boarded and finished with burnished Proline 1088 racing bottom paint.

OBSIDIAN is well prepared for one-design, buoy and offshore racing while retaining the practical interior accommodations that make the J/111 a capable weekender.

Broker's Comments

OBSIDIAN represents a rare opportunity to acquire an extensively updated J/111 with much of the expensive race preparation already completed.

Her professionally prepared bottom and templated keel, recent rod rigging, updated NKE electronics, B&G chartplotter and exceptionally current Ullman sail inventory make her particularly attractive to a buyer looking for a competitive, turnkey program.

With her striking black Awlgrip hull and carbon rig, Obsidian looks every bit as serious as her equipment list suggests.
