J/29 Masthead
Description
The J/29 masthead Rig (1982–1987) is a race-oriented 29 footer. The J/29 is a great performer upwind and can hit 6.5 knots with a 15 knot breeze. The interior is fine for short weekend cruises but it is most at home racing one design or PHRF.

Disclaimer. Boats are not all the same -- even when produced in the same factory of the same model. Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them. You should take the same precautions, especially when the data is not from Sailrite. The information on this site is not guaranteed to be accurate.
