Tarps, block out shades/sails/ air con? How do you cope with the summer heat onboard?

I am a Catalina 34-36 ft fan.
It is the maximum I will get on my mooring.
Still able to sail single handed.
Maximum marina berth length available when I need it.

As all boat owners would know there is a never ending list of things to do to keep your boat in A1 order and I think that this could be an interesting and informative ongoing topic.

Over the long weekend I was able to instal the two new AGM 110 AH batteries after a weekend long chase of terminal posts and bolts to fit and with my son's help removed the bent stanchion and took it to Viking Marine at Taren Point to be repaired or replicated.
