As it happens, I bought that boat that sailed from Canada to Sydney.
(Inboards Yanmars not outboards btw)
Great boat - I love her. Put a big solar array on top & got rid of shore power inlet as it just wasnt needed.
We run offshore sailing (< 100nm) often, and spend a bit of time onboard. She goes GREAT for her intended purpose - but she's no speedboat. 5-9 under sail (surfing downhill on a reach I've hit 13 - wouldn't recommend it though)
She handles rough weather very well too.
If you're ever near Sydney, Australia, (Lake Macquarie), feel free to reach out.
I agree with some of the comments though- replacing the hard top is an option - I'm looking into - 6X185W domestic Solar array custom made to fit current mounts. I also run a 3000/6000W (Peak) inverter for microwave, gerni, laptops etc - and never had an issue.
I LOVE this boat, paid $150K AUS about 3 years ago - and was money well spent.!
Beautiful and perfect cat in many ways, but in Miami (my current residence) keeping a 50' cat is not ea$y. I'm self limited by 45' for lack of sailing partner and available moorings.
This one seems amazing as well:
