[Alberg30] Keels A30/Folkboat

[thedodsons]

And speaking of making use of what's already in your manufacturing
process... the mizzen mast on a Whitby 42 was an Alberg 30 mast.  Thrifty
and clever, if you ask me!

  Until last year my boat #384 was on the hard beside one of the Whitby
built folkboats (Continental Folkboat is one term I have heard).  As Paul
said it has an external iron keel and that was evident by the rusting on the
surface although is didn't seem to be a large problem.  What I found
interesting is as follows.  One morning in early spring I arrived at the
yard and noticed that the ballast on my A30 (staying very cold on a
relatively warm day) had caused frost to outline its profile on the
fiberglass.  I immediately looked over at the Folkboat and voila the profile
is virtually identical to the external iron (very high at the forefoot and
tapering toward the aft end of the keel but stopping well short of the
rudder shoe).  I didn't measure or mark it with anything so I can't say for
sure what the exact measurements are.
  I have a copy of Choice Yacht Designs by Richard Henderson (1979).  He
reviews the A30 (and Triton).  He has a diagram of the A30 hull lines
complete with the ballast outline.  It would appear to extend from just aft
of the watertank and decline at about a 10 deg. angle ending about 1.5 to
2.0 feet in front of the rudder shoe where is drops straight down about 8 to
10 inches to the base of the fiberglass hull.  There is also a bottom up
profile (Iines).  Because Henderson couldn't get original plans of the
Triton from Pearson at the time he wrote the book, he had Carl Alberg draw
him a new diagram of the Triton Mark II.  That plan has a slightly different
rudder which might have been to apease Pearson.  The A30 plan also shows a
squared off rudder.  Perhaps this also reflects Alberg's revised thinking on
rudder profile???
  I will see if I can get an enlarged copy of the page.  If I can enlarge it
properly I can fax a copy to anyone who wants one.
