What Cisco is saying is that you may have to match the the capacity of the 12vt compressor to that of the engine driven compressor. Otherwise the 12vt compressor may not pump enough refrigerant to supply the evaporator.
Tx valve orifices and orifice tubes can sometimes be changed to control the amount of liquid refrigerant into the evaporator and their capacity will directly effect the H/ pressure and the L/pressure of the system. Other problems may occur at the compressor end with the condenser providing too much sub cooling or over condensing the H/P liquid gas.
It probably would be easier to adapt an engine driven compressor for an already electric system ,,even running both types of compressors on the one system.
I'm not sure how it is done as frigeration isn't my trade but on my Cav both a 240v and engine compressor share the same eutectic plate and I can run the built in fridge with either engine or shore power.
Yesterday when I sailed back in to my mooring I was a little surprised to see my tender was missing! I soon found it pulled up the beach near my mooring. Couple of the local liveaboards noticed one hull was full of water and rescued it for me. I managed to row back to the boat ramps and drained out the water. Windrush hulls row reasonably well with just the deck showing! On the trailer with the water draining out the problem was obvious. Years ago when I drilled out the rivet heads for the gudgeons I just filled the holes with epoxy. I left the body of the rivets in place and one of them had popped out. I suspect the back of the rivet had corroded away. Back home I drilled all the old rivets out and oversized the holes to get rid of any of the manufacturers silastic, counter sunk the holes and filled with body filler. 3 layers of cloth and epoxy finished the job. I have been waiting for photos to appear on my GP Facebook page but none yet so here is how she is supposed to float.
Still planing at cutting my cockpit through! Got the cat seasick again on the way to remote islands and upside down! Found a Burke wind catcher and thought I would test it out!
Today the surgeon/butcher has sharpened his tools and made the incision! Dam how can I lock the Cat out tonight!

That will do for today! Close to a walk through cockpit now. I may put doors where the original storm boards went and a new storm board in the new lower cut out!
I forget to take a camera with me when I do work on the boat. I forget half the stuff I am supposed to take with me as well.
Re-arranged the winches on the cabin top and added some (well 10) clutches so we now have a choice of terminating at the mast or cockpit for the lines and halyards.
Gives me the ****s a bit people old school and negitive on this forum. It's not like I cut through a bulkhead! Stupid to have such a step up and over waterproof cockpit if you can't enjoy what you want and not looking at sailing around the world tomorrow.
Mine has the same step, but I enjoy the spot as somewhere to sit and watch the world go by. Doesn't help that all the boat electrics are under the step........
Yep bad design I can take a wave into the cockpit mop up the mess if it comes into the cabin and still have power.
Mk 1 East Coasts and some of the MK 2's had it as a walk through. I suppose the original customers had a choice on the Mk 2. Not worth my time to change.
On the race on the weekend I was concerned the VHF was not receiving as well as i would hope, so I went up the mast and of course everything looks fine. The next step is to get a loss meter and check for attenuation. Wish I was better at heights.
more boat painting ( Grinding, Prep and paint) Looks better just love a steel boat just cannot part with it. Love a challenge......
