We've removed the 20 gallon water tank on Mariah from below the V Berth to a new 10 gallon tank located behind the wet locker. A new water inlet hole needed to be drilled in the hull on the port side to line up with the aft leg of the midship's stanchion inspection port.

New water supply lines run from the tank via a 12V pump located in the wet locker below the sole to a tap in the galley and a hand pump located in the head.

Before marking and drilling

Took the plunge and drilled a 1 3/4" hole

Looking in the hole and through the inspection port into the bilge opening

Below the wet locker side panel often you'll find wetness causing the wood to soak up moisture and rot. In order to avoid this I've shortened the new panel by 1/2 inch and replaced with a strip of 1/2" breadboard type of material (sorry I don't know the name of the material)

You're a brave man Henk to take a hole saw to your boat. Glad it worked out well for you.
Question: how will you run the wires for the pump?

Wayne Cutting holes on the side of the hull is scary business but... it turned out to be in the right place

Dave The half round panel is the new replacement panel to fit the stern battery compartment bulkhead which needed an additional slight adjustment before fitting properly.

The old piping on this panel was still "like new", and could be reused after a good wash
.
The smaller other panel fits the aft berth port side coaming.

In all cases I've used the old panels as templates including the screw hole locations

Catalina designed, fabricated and fitted the individual panels without disturbing or having to remove most others...

Wayne I routed the electrical wires of the pump through a drilled hole from the wet locker to the bilge and below the sole to the galley cupboard where they are connected to the tap via a small sub-panel together with the stove and butane gas sniffer alarm as well.

The beauty of this pump is that it provides water on demand without pressurized waterlines and allows the hand pump in the head to work

Does that affect the balance? I have added flexible water tanks for ballast in the area below the V berth to compensate for the engine's weight (and mine)

On our previous 1995 C250WB a factory installed 10 gallon water tank was placed in exactly the same location.

We used an 8HP long shaft Honda with manual start. The boat was dead on its lines and remained so even though, at one time, we outfitted and provisioned the boat for living aboard for over a year. We also enjoyed month or longer cruises with different gear not causing noticeable changes

Often additional water supply was stored in the V Berth in the form of standard packs of store bought water bottles but with or without we never noticed much or any difference.

It seems that the WB as opposed to WK models may have an advantage when considering waterline and other behavioral issues.

Our new to us '96WB "Mariah" was equipped with a 20 gallon horizontal tank located in the V berth with a fill cap located on the counter awkwardly behind the stove top. Perhaps due to winterizing, poor ventilation, usage, tank draining problems including the lines affected the water supply. Besides taking up valuable storage space while hard to observe hard when filling the tank.

For those reasons we removed the old tank and opted for a smaller, out of the way, ventilated and easy to see when filling the tank from outside the boat.
