{"title":"Gnav System Parts for Dinghy Spars","description":"\u003cp\u003eSeldén gnav system components for dinghy masts and booms, covering the mast bracket, strut, strut end, gnav car, toggles and clevis pins for fitting or servicing a gnav inverted vang system on Seldén aluminium dinghies.\u003c\/p\u003e\n\u003ch2\u003eHow to choose\u003c\/h2\u003e\n\u003cp\u003eA gnav is an inverted vang system where a compression strut runs from the boom downward to the mast base rather than upward in a conventional kicker arrangement. Removing the kicker frees up cockpit space and reduces the risk of crew injury from a kicker under load. This collection covers the individual parts needed to fit or replace components on a Seldén gnav system.\u003c\/p\u003e\n\u003cp\u003eIf you are fitting a gnav from scratch, you will need the mast bracket, the strut, a strut end fitting, the gnav toggle, a boom toggle and a gnav car. The mast bracket is section-specific: the side-mounted cast stainless bracket (508-881-14) fits Zeta, Cumulus, Alto, Epsilon and Gamma section masts. If your mast section is not listed, contact Seldén to confirm compatibility before ordering.\u003c\/p\u003e\n\u003cp\u003eIf you are replacing a worn or damaged component, identify the part by its position in the system. The strut end fitting (507-954) and strut (025-025-26) are the compression elements. The gnav toggle (528-087) fits to the top of the strut. The boom toggle (528-095) is the fitting on the boom end of the gnav. The gnav car (511-805-01) is the sliding assembly on the boom track and fits 2628 and 2633 section booms specifically. The clevis pins are available in two sizes for the gnav assembly.\u003c\/p\u003e\n\n\u003ch2\u003eWhat's in this collection\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003egnav mast bracket\u003c\/strong\u003e (508-881-14) is a side-mounted cast stainless steel bracket for Zeta, Cumulus, Alto, Epsilon and Gamma section masts.
