[Public-list] slab reefing, boom vang

[Gordon Laco]

Oh yeah, that was your original question.  I guess I forgot about it while I
was pounding the table, spilling everybody's beer!

Yes, two reefs is common - if you look at the pictures of us reefing that
George has put on the US A30 website you will be able to get an idea of the
size of each reef.  Sorry, I forget the exact measurements.  I do recall
asking my sailmaker to make both reefs deep.

Re where to hang the vang on the boom... There is no rule of thumb there but
keep in mind that the loading on it will be terrific.  I put ours somewhat
further along that boom than the boom is high above the step.  If I were to
do again I would move it further out.  I think you can see it in the same
pictures mentioned above.

Which reminds me - I sometimes look at that single bolt in the clew end of
the boom from which the mainsheet is hung, and wonder why I depend on it so
much.  I will someday fit a formed stainless steel block hanger there
similar to the one I mounted for the vang.

>> Bernard,
>> For jiffy reefing you only need two grommets for each reef.  (Your
>> mention of "the rows of reef points" sounds like the old method of
>> reefing that ties the foot of the sail at many points). Excuse me if i
