I see your post is quite old but incase you are still looking I can offer my personal experiences on my C-45. I have nbo experience on a Cal 2-46 so this is not a comparison.
The C-45 is great big boat. Very roomy and TONS for storage
for cruising. I am third owner of this boat (4 years now) and purchased her from a cruising couple. They lived abord her for 10 years cruising the Caribbean
extensively. Made the entire circuit many times.
That said...I would not consider her a World Cruiser. Windows too big for one and this sloop
rig does not carry enough sail with her short mast
. She a motor/sailor though and with one fuel tank
can go over 1200 miles on engine
alone. With optional second tank double that.
I have not had ANY issues with quality. It is a '73 boat so all rigging
has been changed with exception of chainplates which are huge and in my case in excellent shape. One issue some mention is the steel
keel strongbacks. There are four of them, mounted transversly above the keel. They sit in the bilge
is present. They will require replacement at next haulout but they are easy to fashion. I will go back with steel but powdercoated. Easily get another 35 years on new ones.
Mine is the shoal draft
model (5'3") and has extra ballast. She is both faster and more stable than the deep draft version which has 7' draft but 500 lbs less ballast. Mine is equipped with the Perkins
4-236 which is an awesome motor
. Love it.
Everything in this boat is KISS. No headliners, no hydraulics, etc.. but she is a beast. I am refitting mine for a cruise
back to the Caribbean
in a few years. Until then, she is a wonderful livaboard and coastal cruiser.
