[Public-List] Mast Beam Repair

[Roger L. Kingsland]

C. B.

A foot of deflection!  That's not a mast beam, it's a crossbow.  I can't
imagine my reaction upon  observing that, especially in bad conditions
(probably would involve a combination of swearing and drinking;  something
like holy wee wee Batman, pass the Scotch).  I guess it underscores the need
for a good repair.   

Has anyone tried to calculate the compression load of the mast?  I am
exploring adding wood posts  under my beam near the door jambs to reduce
twist and need know the load on each.

Best,

Roger 148

Folks,

The simple fact that Whitby went on to change out the original design from a
laminate beam to an aluminium I-Beam suggests to me that repairing the old
design is a waste of time. Taking advantage of the sistering repair is smart
and responsible seamanship.

I have watched Infinity's Beam flex a foot or more in 30 knot winds in big
chop. Once I saw that I was convinced that the upgrade was necessary. Take
it from those of us who have raced these boats in the toughest of conditions
- Mike Lehman, Larry Morris, and myself - do the upgrade and ensure that
your boat will be in the best of possible condition to handle what A30s are
really made for.
