converting a used sailboat for ocean vovage

Over the winter i've been re-reading through my library of books about
small
boat singlehaneded passages. Just finished Trekka by John guzzwell about a
cir***navigation in a 20 footer''
It got me dreaming about someday doing the same

I'm looking for suggestions for production boats in the 22 to 28 foot
range
that might be converted for a cir***navigation.
Any suggestions on a model availble used in this category??
I'n wondering abviout the J-27 available locally for 20 grand used. looks
lik a sturdy and fast boat
Adding a roller furling jib an beefed up main with jiffy reefing and a
steering vane and maybe renewing the rigging upo a size or two and
possible
cutting the cockpit size down a bit
any other suggestions??

Ley me know what you thinK\\
