The Tayana and the CL-P36 have almost identical base numbers, although
the TY37 is a bit faster (hull speed).
Interestingly and due to the displacment weight vs. volume, the Tayana
will carry more load while the CL will be a better boat in light and
flukey conditions and when 'light'. The CL will have better
acceleration than the TY37; but, the TY37 will definitely carry more
stores and still be able to sail on her design waterline. .
The CL at 16.5K lb. when loaded with a normal crusing 'load' will be
deeper in the water and hence will affect sailing performance more. The
TY37 at 22.5K lb will not depress the water line as much hence will
retain her sailing characteristics to a better extent .... plus the
motion comfort of the TY 37 is 25% better. The caveat is that some
sailors puke more with a faster reacting boats and some puke faster
with slower period boat. The CL having a faster roll period, the TY37
slower.
The CL will not need to be reefed as frequently as the TY37 as the CL
SA/D is lower, meaning a more easily driven hull. But when fully laden
those numbers should drastically shift in favor of the TY37.
So, your reply about the CL being a better passage boat will only be
true at the end of the passage when all food, fuel, etc. is used up.
Heavily loaded at the beginning of a passaage the CL will be very deep
(comparitively) in the water and wont perform as well as unladen...
and will always be slower. The TY37 will stay more 'consistent'.
Its not impossible to add a ton or two of 'stores' when voyaging, ....
added equipment, emergency food/equip, accumulated junk, rocks, shells,
funny hats, booze, etc.
As far as the TY being top-heay .... sometimes true and sometimes not
..... as it depends on the arrangement of the (teak) interior, teak
deck or not, wooden spars or aluminum and amount of teak that the
original owner specified or omitted topsides. Remember that TY37s are
'semi-custom' boats and the original purchaser had a lot of influence
on the final displacement 'loading' of the boat.
