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 Aluminium

SPL (J): Maximum spinnaker pole length for your yacht.A whisker pole should be approxi-mately as long as the foot of the sail you intend to pole out. RM 30° Displ. 48/48 60/60 72/72 84/84 96/96 99/99 kNm tonnes 8 1.6 3000 10 2.0 2700

haul attached via a bridle or at
the outboard end. If a central
attachment is desired, the pole
diameter must be increased to
the next size up. 4150 5410 6850 90 14 4950 6540 8110 100 15 4770 6270 7770 110 16 4600 6030 7480 120 18 5830 7230 130 19 5640 7000 140 20 5330 6790 150 22 5190 6600 160 23 4950 6440 180 31 4750 6140 200 32 5890 220 34 5670 240 35 5480 Topping lift bold blue When SPL is within 500 mm of a dimension shown
in , a bridle topping lift is recommended if downhaul is at outboard end of pole. For 99/99 and larger diameter poles, use outboard end lift only. 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. * 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. 132133
