[Public-List] Jib sheet winch

[RogerW]

Hi y'all, I've done some looking at pictures and posts, but need more. 
My friend's "new" A30 has two winches per side, the foremost smaller one 
is apparently for sheeting the smaller jibs from the fairlead block on 
the deck near the shrouds, since the angle to the toe rail gets too 
steep with a larger genoa jib and the sheet block car pulled back. The 
aftmost larger winch has a better angle for very large jibs with the 
clew well aft, led through the toe rail block car on it's track. There 
is a stationary padeye mounted aft of the rear winch on the toerail (for 
spinnaker turning blocks?). He has upgraded to self tailing winches in 
the forward positions. Old large original human-tailed winches aft.
  Question 1: Would it be reasonable to put a turning block on the 
padeye to use the self-tailers? What of the spin sheet then?
  Question 2: Should we change the angle on the forward winch base so 
that it lines up with toe rail and deck fairleads?
   I'm probably going to do the work, as I'm replacing the winch bases 
and eventually the coamings.
Thanks in advance, RogerW
