How are sail Luffs measured?
While the sail is still laid out go to the Tack and lay the tape along the luff of the sail as if you were extending the edge downward. Draw an imaginary line to the intersection of where the Luff and Foot would meet normally, this is the measurement you need.
How do you measure a sailboat rig?
Mainsail Rig Specs Measure straight down along the mast to the top of the boom at the tack. Disconnect Mainsail from Halyard. Be sure the boom is in the normal sailing position. E – Maximum Foot Length: Measure from the aft face of the mast to the shackle of the outhaul.
What is the position of the sails on a beam reach?
Beam Reach – This is the fastest and easiest point of sail. The windis on the side of your boat (beam) and you’ll sail with your sails outhalf way. Broad Reach – On a broad reach you’ll be heading a bit further downwind, so you will have to let your sails out a bit more.
What do sail dimensions mean?
Foresail and mainsail dimensions are universally referenced with the letters ‘J’, ‘I’, ‘E’ and ‘P’ approximating to the length of the foredeck, height of the mast, length of the boom and the height of the main sail – but more accurately defined further down this page.
How do you calculate the length of a halyard?
A general rule of thumb to calculating the length of halyards is to use the ‘vertical’ P / I measurements (height of the mast), while calculating the length of sheets then uses the ‘horizontal’ E / J, plus overall boat length.
How is forestay length measured?
Measure the distance from the forestay attachment point on the mast to the bottom of the forestay where it intersects the deck. STL is measured with the mast up. It is the longest of any of the following: Spinnaker pole length: Rig the pole at a convenient height horizontally on the mast on the centreline of the boat.
How is rigging measured?
When measuring rigging, the convention is to measure from pin center to pin center or from bearing point to bearing point.
