Catalog excerpts

Selecting the right pole Just look in the appropriate table for your yacht’s displacement or righting moment (RM) at 30° heel, then look right for the value exceeding your SPL or J value (shown in the sail plan). Example: For an aluminium spinnaker pole. Yacht displacement 8.0 tonnes, SPL is 6100 mm. The correct section is 99/99. Table terminology RM: Righting moment at 30° of heel. Aluminium spinnaker pole selection max SPL (mm) RM 30º kNm Displ. tonnes A whisker pole should be approxi mately as long as the foot of the sail you intend to pole out. SPL (J): Maximum spinnaker pole length for your yacht. Downhaul Poles should have downhaul attached via a bridle or at outboard end. If a central attachment is desired, the pole diameter must be increased to the next size up. 120 Topping lift When SPL is within 500 mm of a dimension shown in bold blue, a bridle topping lift is recommended if down aul is at outboard end of pole. For 99/99 and h larger diameter poles, use outboard end lift only. * Max available SPL with composite end fittings, attached to a fixed mast ring. If the pole is to be “Dip Gybe”, max available SPL is increased by 165 mm.
