Whisker poles should be 100% of the foot of whichever headsail is being flown. Measure from the tack to the clew and the whisker pole should be this length. You need to have some overlap in the pole. Poles telescoped to their maximum length are at their weakest, strength-wise. Diameter is a major function of strength. A 2-1/2" diameter tube is as much as 70% stronger than a 2" diameter tube. Size does matter! The Forespar® catalog and Whisker Pole brochure have a sizing chart based on 36 years of empirical data. Labels on the whisker poles themselves also note the maximum size boat for each pole. This is what we strongly suggest you use in selecting the proper sized pole for your boat. Forespar® cannot offer any warranty on poles that are too small for the boat, based on this chart. Contact Forespar® customer service if you have any questions on proper sizing for your boat.
The smaller, twist-lock style poles (ADJ 4-8 & ADJ 6-12) come with a mast pad eye properly sized for these poles. This eye only should be used with these poles. The larger twist-lock style poles (HD 6-12 DL & ADJ 7-17 DL) should be used with the Forespar® PE-3-SF (#400001) or PE-3-SC (#400002) stainless steel mast pad eyes sold separately.
Any fixed mast pad eye should be mounted on the forward centerline of the mast. This is so you can fly the pole from the single mount on both port and starboard sets. The height of the eye on the mast is determined by the height of the clew when the headsail is set. You want to fly the pole level, so if you have more than one headsail and they have different clew heights, you may want to mount two mast pad eyes, one high and one low.
I don't understand why they recommend that pole. If it only extends to 15', then it's too short for a tall rig that has a 16'-10" foot, or std. rig that has a 16'-6" foot. It's almost 2 feet too short!
