Not sure how well this applies to the C30 but here goes. I added the tee in the washdown line just past the pump and ran a continuous line up to the bow on the wall of the engine compartment, under the cabin step into the cave (quarterberth), behind the mouse fur covered baseboard in the cave, under the navigators seat and feet, under the the v-berth liner, and through the forward V-berth compartment under the floor panel where the bow thruster is. Removing the port bulkhead panel in the aft of the V-berth gave access to the space under the V-berth liner. Most difficult part was mounting a hose bib connection in the anchor locker and making the connection to line coming from the stern. I ended up using a short line pre-connected to the hose bib and then using a coupler hidden behind the foremost panel in the V-berth. I keep a coil hose attached with nozzle in the anchor locker itself. Just have to remember to turn on the wash down before going forward and pull out the coil hose before dropping or retrieving the anchor so it does not get tangled with the rode. We anchored over 40 times on our trip to Alaska many time with a very early daybreak start. The anchor locker washdown made cleaning up the muddy anchor, chain and foredeck a breeze. I can’t imagine going without it!
