It really is rather simple to do the measurements. You just attach your tape measure to the halyard
with a down haul. You then hoist the tape measure and measure both the height against the mast
and the hypotonuse. Then measure the base. Really simple.
You can look at Sailrites website (www.sailrite.com
), they have detailed instructions for doing the measurements. I imagine it wont take you much longer to do it yourself than to find a pro, watch, then pay them.
Here in Florida
, everything seems to take $100/hr. so I imagine $100 for measurements. In North Carolina
, I'd just ask someone in the next boat.
