2018 J Boats J/121 sold



Jackhammer is a lightly used, fully equipped and ocean race ready J/121. The boat was launched in 2018 and sailed in the Newport-Bermuda Race, finishing 3rd in her class, and was subsequently sailed in a few other events in 2018 and 2019. Due to Covid, the boat has been on the hard since the end of the 2019 season. Jackhammer has most all the available factory options, minus water ballast, plus many custom options like a fixed carbon sprit in addition to the factory extendable pole, a Gori 3 blade prop, and an EFOY Fuel Cell Generator. Add in an extensive offshore electronics and navigation package, complete sail inventory and comprehensive running rigging, and you are ready to race as soon as the boat hits the water.
