My friends lived aboard and cruised a
Cal 2-46
ketch for years and I believe the quality of the craft to be very good. I helped them do a couple of short channel
sails. Although it was very comfortable for four aboard it was 10 feet too long for my liking. It was more a
motor sailer. The
keel was short and long and the
rudder was small. I don't know what the underbody of your 35 is like.
The
Perkins is a forever engine. Yanmars are good too but whenever you change engine and drivetrain there are hidden costs in time and
money. I know from experience.
The raised
cabin with large
portlights lets in a lot of light and makes it feel much larger, however, in the tropics it is a greenhouse so you need a lot of ventilation to cool things down. Everything with sailing craft is a compromise.
Good luck in your choice and I hope this helps with your plans.
Kind Regards,
