[Public-list] Mast rake and shroud tension

Edward:
A word of caution. Be very careful tuning the rig of an Alberg 30. Over tightening the shrouds can cause serious damage. With a deck stepped mast and the main beam problems that A30's have you can easily bend the beam and cause the mast to push the deck in. Cruising rigs should be loose. An A30 is basically a cruising boat. It is raced, but not in the same way that the typical racing sailboat is raced, with tight rigging and adjustable rake, mast bend, etc. Keep the shrouds loose, but secure, with even tension.

  I can answer 1 of your questions - the boats with the higher tensions well 
  all avid racing boats. The Alberg likes the the mast 'in column' and not 
  'raked' - forget anout bending the mast on the Alberg.

  This month's edition of Good Old Boat has a good article about standing 
  rigging tuning. I have been tuning my rigging on many boats for many years, 
  never with a tension gauge. I have also re-read the "Survey of A30 Rig 
  Tensions" from our Alberg website. I have already re-attached Emotional 
  Rescue's chainplates with larger bolts and stronger bulkhead as previously 
  recommended. I still have a number of questions.

  1. Why the large variation in tensions measured and recorded on the 
  Survey?
  2. What tension would one use for a 1968 boat, #303. There are none in 
  the 300 series.
  3. Does anyone know what the mast rake should be? As long as we have only 
  enough weather helm does it matter?
  If it ain't broke...?
