I started this thread and appreciate the feedback. My wife and I put our heads together and took a different twist on the lounge deck
drainage which I will try to explain.
The primary component involved draining water from the area at the top of the lounge deck stairs. #1. We removed the top fiberglass
step, moved it starboard as far as possible and enlarged the drain hole to 1 1/8". #2. We modified the stair unit going up to the lounge deck. Kato Marine
cut off the bolt at the bottom of both ladder rails, closed the drain hole, and welded on an exterior support plate and a 4 inch long drain pipe that would accept a 1" ID flexible water hose. #3 We ran water hose from the bottom of the stair rails to 2 plastic fittings that drain into the well between the cockpit and salon
. Access to the underside of the stairs is through the speaker hole; I have never been able to remove the cockpit fridge. Test if you can reach the back of the drain well before drilling; think skinny with long arms. Total cost about $600
Secondly, we added a shower
threshold behind the helm station port side backrest to keep water from draining onto the helm seat. Threshold came from Home Depot online. Cost $47
Third, we custom built a 3/4 inch thick block of King Starboard to keep water from draining into the helm station where the main traveler and port side jib
sheet traverse under the lounge deck. Cost $3
Not much rain lately to test our drainage; however, it handles a garden hose flow very well.
Let me know if you have questions. I hope this is a contribution and helps the next person doing the same project
