1999 J Boats J/125
Boat Type: Racer Address: Unknown, AG Price: $259,000


The 41' J/125 is as close to high performance big-boat sailing as one can find in a boat that's manageable by two or three people... even with a spinnaker! Aunt Jessie provides a rare opportunity to get into what is one of J/Boats most thrilling designs. She has been professionally maintained and is race ready. Aunt Jessie has been sailed lightly since having undergone a complete refit in 2009 and has been a much loved family boat for the past 6 years. It is with great reluctance that the owner is selling "the best boat he's ever been on".

3-7-2012 AUNT JESSIE just took 2nd place overall at the Heineken Regatta in St Marten!!

Ballast (lead)4,6462,107






Displacement on the 41 foot long J/125 is 8,350 pounds on a 37 foot waterline with a 57% ballast ratio, beam of 10.6 feet and draft of 8.0 feet. Upwind sail area is 1071 f2 with downwind sail area of 2464 f2. 


The J-125 is a boat of exceptional stability and power. Her handling is explained by an extraordinary stability index of 143 degrees, with a stability curve ratio of positive to negative areas of 12.5:1. This greater stability is combined with a balanced hull-form with proper amounts of reserve buoyancy forward. This provides safer and more controllable high-speed planing offshore in large waves as well as a wider steering groove upwind for sustained peak performance by average helmsmen. No IMS rule-inspired hull form can match the high 4.72 length-to-beam ratio of this seakindly yacht, nor the reserve buoyancy designed into her bow sections. High length-to-beam ratio ensures straight tracking in rough seas and light steering loads. Sailboats with fine bows and full midship sections are more difficult to balance and more likely to spin out of control in big waves. As user-friendly as it may be, this is a sailing machine designed to be the fastest, best-built boat of its type in the world. A long-lasting, high-tech carbon - Kevlar - E-glass - epoxy laminate is the answer. TPI Composites is the world leader with its patented SCRIMP process. This yields a laminate that's been tested by the US Naval Surface Warfare Lab at double the strength of hand lay-up construction. SCRIMP overcomes long term ownership concerns about delamination and structural failure because there are no air-pockets in the hull laminate and integral keel beam grid. Secondly, the ratio of glass fiber to resin is 2:1 rather than 1:2, resulting in a strength-to-weight ratio that exceeds custom race-boat, pre-preg construction. The J-125 sets a popular offshore "Grand Prix" standard. In the first 90 days, J-125s won yachting's Block Island Race Week and the Maxi Division of the St. Francis YC Big Boat Series on San Francisco Bay. The fact that crew size in winning Block Island varied from 5 to 7 people indicates that this is not the typical 40' racer needing 12 people on the rail. Nor does it remain parked on yard stands between races gathering dust.
