[Alberg30] Towing by bow cleats

[Mike Lehman]

There have been several Alberg dismastings due primarily to three failures 
1. spreader failure 2. forward lower failure (ala Yves Gelinas "around the 
World") 3. collisions (with other boats, bridges). You can start a fouth 
category by towing your Alberg from the mast step.

Sanders ... I think the question might be ... if there is to be a
failure would you rather it be a forward cleat, a main sheet winch or
the intire rig? If your Alberg was new the mast be ok but since many of
these boats are far from new which would be the more prudent choice. I
do believe there have been some instances of dismastings. I recall one
involving the gentleman who made a circle navagation.
