Whisker Pole Questions Checklist
To help you get the correct information needed to properly size a whisker pole, please use this checklist. This will help you and your customers choose the proper style and sized whisker pole for the boat.
The whisker poles length needed, when flown conventionally, is 100% of the foot of the sail being used. Measure from the tack to the clew and you have the pole length needed for that sail. Telescoping poles should always have a reasonable overlap or safety margin. It is unwise to use any pole, fully extended, with large overlapping genoas in medium to heavy air. (15-18 Knots apparent and above.)
If you answered yes to questions #5 or #6, seriously consider going up one pole size for strength. If you answered no to #7, consider adding "T" track to the mast. This is much stronger than a single eye and allows adjustment of the inboard height of the pole. If you answered yes to question #8 you need to consider the vertical pole storage car option found on page 12 of the 2003 Forespar® catalog. These cars, sized based on outside diameter of the outer tube, along with a DC-2 (#300002) chock mounted on the mast, just above the boot, will facilitate vertical pole storage.
On smaller boats (up to 25’), a fixed mast eye may be sufficient on the forward centerline mast. The ADJ 4-8 and ADJ 6-12 poles come standard with a mast eye (PE-1). This eye only should be used with these poles. The HD 6-12 and ADJ 7-17 size poles require one of the S/S mast eyes PE-3-SF flat base (#400001) or PE-3-SC curved base (#400002) found on page 5 of the catalog for proper function (sold separately).
Never attempt to extend or retract any whisker pole under load. Furl the headsail or otherwise de-power the sail before setting or taking down any whisker pole.
