1977 Cal 34 Mk III
I currently own "Sea Beast", and would like to learn more about the construction details of the hull. I have replaced the propeller with a
left hand rotation 16" X 12" X 1" 3-blade that performs extremely well.
I have found her to be an excellent sailor. After buying her, without
a sea-trial, I was pleasantly surprised at how well she handles.
I would like more information regarding this design, what improvements
have been made by owners, what works, what doesn't work.
Sea Beast has a Westerbeke 30 h.p. diesel engine.

I am the owner of a 1977 Cal Mark III also. I bout the boat from a local marina, but it had been stripped of sails, interior and whatever else could be stolen. Well anyway I am ready to begin putting it back shipshape and am ready to enjoy the baot.
I am in Charleston, SC..

For a Cal site, perhaps this
Cal Sailboats
is what was in mind?

I own a Cal 3-30, BTW

Hey, I lived abord a Cal 34 and sailed it all over the Maritimes. She is a great boat, plenty of room down below and she sails very well. Quarter berths are huge! I'm 6'6" and had no problem sleeping in them. She has a very long boom, so wach out when you gybe, it swings by pretty fast. I never managed to make her hove to well, she was always beam on to the waves... We built a self steering that worked very well, 1 of the best upgrade we did on her. Here is a link to a video of the vane in action:

We only had 1 reef in the main sail, but that with a small storm jib was good enough... Although I would rather have 3 reef.

Once we got hit by a pretty bad squale that came out of nowhere, we hade the genny and full main, she handled it like a Champ! she heeled over hard, winches and cabin side in the water and turned into the wind, so we could lower and reef the sails.

Spreaders were wood, might be a down side but it didn't bother me much, we had to changed then once and it was all good. I used to climb up the mast once in a while to have a look at them...

One thing that i noticed is that when there is just the right wind, the hole rig starts to shake back and forth. I never saw it happend on other sailboat but i'm thinking that a baby stay would fix it.

A other thing is that we didn't had a turn buckle on the front stay, the rig was made that way and it was kinda anoying...harder to ajust the rig well, but she was always nicely balanced.

Lots of room on deck to work but not much to hold on to when trying to reach the front deck to bag a sail or something when the boat is healded over hard and bouncing around.

We installed shore power wich is great, we also swaped the ici box for a small fridge. We tried a compostable head, didn't like it much so we replaced it with a regular jabsco wich was fine. Painted the builge with epoxy to prevent delamination. Installed a boom vang.

We changed the rope-wirer halyards for all rope and in my opinion this was much better.

Oh yeah, and she is pretty fast too!

Feel free to ask any question,
