Plumbing broken -- underway on delivery voyage

It's entirely possible that it empties directly overboard and the hull discharge is clogged with a mud dobber, or god forbid the yard left tape on it when they painted the bottom.

Weird...gray water sharing black water would mean that every drain must have a wet trap. Sitting could cause a clog. Air. Snake. Both good options. If you can trace the hose you have the potential to use compressed air in either direction. The addition of traps to the equation may be the culprit.

Previous owner of mine had the yard fare and repaint the boot to dress her up to show. They fared over the heat exchanger discharge for the raw water heat exchanger that cooled the stabilizer hydraulics. Not an easy discovery....but now cured...

Yes, never chemicals. Compressed air is much more useful and safe.

A good preventive measure is to use a lot of water when flushing. The more water you use, the less calcium deposits you get inside the hoses. Talking fresh water if course... no idea why any one would still be using salt water except on very small boats.

my personal 53 had new vacuflush installed back in the late 90s. One of the benefits often touted about VF is the low fresh water usage. Great, right? Wrong. After 15 years some of hoses had significant build up.

on the other hand I recently replaced a check valve on a headhunter head which uses quite a bit of water as they rely on water pressure and was amazed to see how clean the inside of the pipes and the check valve. No deposit whatsoever

Since that, I flush my new Raritan heads for much longer than before

Nah, relax:
He did not give you tone, or attitude, he was simply asking a direct question.
This place is not for the faint of heart, but there is tremendous information available right here, right now.
Enjoy and learn.

common on steel boats that have been sitting. Generally they use welded steel pipe for drains instead of hose. The pipe grows rust burrs on the inside of it (much like cast iron on older houses), then every **** thing catches on the burrs…….hair, soap, drain babies, etc.

Well here she is, I hope the owner dose not mind me posting pictures of Rainbow Maker but she sure is a nice boat.
They arrived Welland Canal this morning and needed crew as I was busy today tried to find help for him but none of my guys were available owner found a local friend who worked the lake freighters to help them through canal. It has nice wood stove to. Had a nice chat with the crew. I saw this boat years ago going through the Welland Canal I am sure it was a local boat at one time.

Canal is very busy today they will be staring around noon today and will be a 10 -12 hour trip

Designed by Dutch Naval Architect John Jansen in 1998 to a classic Dutch style for a coastal boat and built in 1999/2000 by Quebec yard Chantier Naval Forillon for a Gerald Verlaan specifically to do the Great Loop. The yard is known mainly for stout fishing boats, is still in operation and currently has 6 SAR craft in build for the Canadian Coast Guard. Very pretty little boat in the old style.

Wow, nice but not my kind of boat, fireplace and all.
(I sail into the sun, never North of 25N.)

Absolutely gorgeous!!!!!
