If you have a driving rain due to high wind, water can get in. However, let me address the two issue.
Opening port. If seal needs to be replaced between the lens and frame, then replace it and ca glues or a crazy glue will be used to attache the seal. Secondly, the caulking could be bad. Remove the window and outside trim ring. Remove all the old caulk and re install window and apply alot of architecutal grade pure silicon and then affix the trim ring. Make sure that you use the sealant well and then clean up with alcohol, not acetone as it will attack the plastics and lexan.
As for the second issue of the companionway slider, there are two teak strips and the one that could be an issue is the stop piece to prevent the lexan slider from coming out which is on the top. I suggest two people for this. Remove the screws on one side of the fiberglass top of the companionway cover and then remove the lexan slider portion and you will seee the strip. Take it off, clean off all the old caulk and recaulk not only around the screw holes but put a bead of silicon alot of it on the bottom of the strip all the way across and put back on. What is happenning is water is coming under that strip and falling into the cabin.
Although many have solutions to keep the water out, the simple fix is to order a companionway slider cover from this site and the piece is a good one. When you put it on, makie sure that you have a throwable underneath it on top of the slider hatch. If you have the camper top, order it without the snaps installed and put them on to match those of the camper top.
If there is still water under the floor, then there is another issue going on. Keep us posted sir.
