GNAV (or upside-down, reverse thrust vang system) provides the ultimate solution for extra room and quick tacking. The GNAV's are very popular for both racing and recreational boats due to the huge gain in cockpit space made by removing the conventional vang kicker. Lightweight, efficient and very strong, it offers a multitude of options for controlling boom thrust and increasing cockpit space.
The boom inboard end must be SLD50907802. Bracket part numbers: SLD50842614 & SLD50827314 are for use with new type boom inboard end SLD509081xx. If SLD508273/737 GNAV bracket is used, the sail entry top must be at least 240mm above bracket center. The standard GNAV assembly SLD02502510 includes strut and slide. When using this, the distance between boom bracket and GNAV bracket center is 590mm.
