Re: [bolger] Chebacco 25 ballast
Well, it didn't seem that anyone here has the answer to that question, so I measured the drawing in BWAOM and calculated the weight as 465#.

Subject: [bolger] Chebacco 25 ballast
I have become enamored of this boat lately and would like to do a bit
of analysis of the design. The drawings in BWAOM appear to show a bit
of external ballast on the keel. Does anyone know if this true and if
so how much? Thanks.

Chebacco 25 is one of my all-time favorite designs. I especailly like
the outboard motor location and it's ability to plane according to
PCB. In addition it would look like a great motorsailor with the
off-shore type pilot house that PCB has drawn for the regular version.
A potential problem might be with the centerboard's exposure to
becoming jammed with crud in a shallow berth? Could lining the case
with UHMW help in that regard I wonder?
