About the J/125
Carbon spar,carbon rudder. Special light weight hull. epoxy w/ carbon reinforcement.
Designed by Rodney S. Johnstone and built by J Boats Tillotson Pearson (USA), the J/125 is a rare fractional sloop with only 16 hulls constructed between 1997 and 2003. Its scarcity and specific production window make it a unique entry in the J/Boats lineup, distinct from their more common trailer-sailer models.
- Best for:
- This boat suits experienced sailors seeking a high-performance coastal cruiser with offshore capability, particularly those who value the fractional rig's tuning potential and are comfortable with a narrow beam of 10.6 ft.
- Bluewater capability:
- With a displacement of 8350.0 lb and a capsize ratio of 2.09, the J/125 offers moderate offshore stability, supported by owner reports of solar and wind generator installations indicating preparedness for extended passages.
- Comparables:
- Comparable to the J/130 and J/135 due to similar fractional rig configurations and performance-oriented hull forms, though the J/125 is significantly rarer with a much lower build count.
