So we decided to go for a local cruise and then spend the night at our slip to see if the ac could handle the heat in the evening to our comfort. Brought an additional oscillating 16" fan to hopefully compliment the small Vornado fan that I have on the floor of the salon in front of the ac output. The day temp reached 94°f and the night/early morning went down to 81°f. When we made it back into the slip it was about 4pm and we turned on the ac. Took showers and went out to dinner to see if the boat cooled down enough. It took about 5 hours to become tolerable while we watched the TV. When it came time to sleep we closed the v-berth door, which does help cool it down as we have a dedicated ac vent in there. It became marginally cool in there with our dc fans blowing but certainly not as cold as we remembered our use during vacationing last October and November. Still looking at either replacement of the unit, adding an additional unit, or just wait until cooler weather for us to go for our cruises to other areas for a week or so wherever we go. Obviously waiting is the much less expensive option. We use the boat weekly for local cruising but don't stay on board at night.
