Select Your Alado

Not sure of the forestay diameter and width?

Follow this guide to determine these important numbers.

Don't assume other websites with sailboat data are correct.











Find the diameter of your boat's forestay in the 1st column and note the Maximum Foil Length in the 2nd column.


If the length of your boat's forestay is equal to or less than the Maximum Foil Length, then select the Alado Model in the 3rd column.

If the forestay length is greater than the Maximum Foil Length then deduct the length of the bottom fittings and top clearance.

If the forestay length still exceeds the allowed length for the forestay diameter, please call our Tech Support at 


for assistance.

Note: Boat Length is not needed when sizing.

The drum sits on the shoulder of  the swage.

The outer drum will be secured to allow the inner drum to spin.

In some applications, this can be done by either a stainless-steel rod or by two lines connected to a rail or on deck.

The Bow Pulpit is the most common way.

Measure the distance between the bow pulpit rails to the forestay deck fitting to ensure there is sufficient clearance on each side.
