Holding tank to installed aft mid-ship companionway steps/ladder

[garmoa]

My boat guy is telling me that he can install a 25-gallon holding tank aft of the mid-ship companionway steps/ladder and enclose it with wood. Any comments on this idea would be appreciated. Thanks. Gary Moates, 817-455-9333

Interesting idea. How would that affect use of the companionway? I’ve often thought of how to mount a holding tank so it would gravity drain overboard but can’t come up with a viable solution. I thought of using the wet locker next to the ladder for the forward companionway but mine houses the A/C and watermaker.

Have you considered a bladder tank under the main saloon floor with access from he floor board that is there? It does not drain obviously but it holds about 40 gallons. Mine was custom made by Husky Portable Containment to the drawing that I supplied. They were very helpful. it was about 315.00 in 2008 They also had great service. I had a small leek years later and they sent me a repair kit N/C

It has worked well. You can vent it to the mast which is an excellent chimney
