I am rebuilding an Olson 30 in the Houston/Galveston Bay Area (Hull #158,=
"The Hawk"). I have the only O-30 in the area so it is difficult to lea=
rn from looking at other boats. Have read virtually everything on the bo=
ard relating to hull, rigging, etc. This boat will be used exclusively f=
or PHRF racing on Galveston Bay and offshore in the Gulf. Would apprecia=
te any help with the following questions from anyone:
- Am converting the single spreader rig to doubles (have parts from Ba=
llenger). Can I assume that baby stay can be eliminated ?
- Plan to stiffen hull with 2" square aluminum beam between chainplates.=
What are the "jock straps" that I have seen mentioned on some posts ? =
Is the hold down fitting from the forward face of the mast up to the deck=
necessary ? This fitting is missing on my boat but from my reading it s=
eems to be inadequate and/or underdesigned.
- From reading old specs on the boat it sounds like some boats had an =
adjustable mast butt. Do competitive boats have adjustable steps ? I am=
going to have to rebuild the mast step due to compression of the primary=
cross member (had dropped about 9/16"). If adjustable step is desirable=
does any one know of a good source ? I will talk to Buzz Ballenger abou=
t this but have not been able to reach him yet.
- Running backstays, I know class rules don't allow them but would any=
one advise their use for PHRF. Will probably fit t-ball sockets for runn=
er and checkstay anyway so I'll have the option once I learn to sail the =
boat.
- tiller yoke fitting, my welded fitting is broken, anyone know of an =
off-the shelf source for a strong replacement ?
Thanks for any comments or help.

different than before. I measured head stay length, mast height off the =

as measured from - the top of the jib (center) halyard to the center of t=
