Catalina 30 starboard water tank

Looking to fix starboard water tank leak, how can you access discharge fitting on tank? PO put a refrigerator in the space where the batteries use to sit under the nav table and I can't see the end fitting on tank, is there a access panel under the nav station? My bilge kept filling with water from a leak on the discharge part of tank. Also, can you remove tank? Seems that the factory fiber glassed panels near the tank so it wouldn't move and you can't pull tank out unless you cut the tabs. Thanks

On my previous C30, the water tank was boxed in with plywood glassed at various places- imposible to remove the tank. I did have the "opportunity" to remove the fuel tank that was glassed in with tabs. I used one of those vibrating tools with a new blade and breezed thru the removal. Also, there has been a lot written about the repair of poly tanks - epoxy is not going to work. Recommendation is to research the leak repair and have a viable solution prior to start. If its not a cracked fitting, then using a better thread sealant (not teflon tape) will work.

On my 93 the starboard tank is forward of the battery compartment. Both are under the starboard settee.
My tank is also held in place with plywood fiberglass tabbing.
The tank discharge fitting is accessible on the aft end of the tank. There is a valve and hose fitting. Hopefully one of those is cracked on your tank. If the tank itself is cracked you will probably need to pull the tank. I just pulled my bow tank to clean it but it wasn't tabbed in place.
