When I look through the Forespar documentation they recommend for boats up to 33' (next lower size on chart is 28') to use their LC10-18 whisker pole. In a couple of other places for whisker poles they recommend a spinnaker pole be about the same size as the J specification which from Catalina's site for the 310 is 11'9". As I have a 135 genoa on my 310 which size pole should I be looking at - a LC10-17 or a 7-17 or some other one? My plan is to use the pole in light winds using either my genoa or a drifter I kept from my old boat (note the drifter is smaller than my genoa, but very light and great for light wind). Thanks Ray
