[Public-list] Mast rake and shroud tension

[Mike Lehman]

Some of the boats I have been on are too loose, which is just as bad or 
perhaps even worse. With a too loose rig, when  pounding through waves, the 
shock loading is tremendous. So John, is right, be careful - too loose = no 
good and too tight = no good.

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.

Ed,

   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...?
