OK, gonna broach a new project
for the forum. All you cruisers with big older boats should pay attention to this one. My boat came to me with the original tanks
. That's 450 diesel
in two tanks
, 540 water
in two tanks, about 60 holding, and two grey water
tanks at about 40-50 gallons each, all of them stainless steel
from 1983. Potentially not good, and one of the major projects for this refit
. Every single
tank on the boat is much too big to be removed. Massive amounts of interior
would have to come out, as well as the pilothouse roof. While I have done that on other boats before, I didn't want to get into it here, mostly because of the acres of bookmatched teak
paneling in this interior
, and the sheer complexity of approaching the job that way. So I pondered for quite some time as to how to approach the issue, then made a plan. Even posted that plan here, with the usual total lack of interest. Hoping some pics will bring the concept
home. I know many here could potentially be facing a similar issue at some point, and this was a massive money
saver I did all by myself.
We began by carefully inspecting and pressure testing all tanks. Our benchmark was 3 psi for 24 hours. All tanks were bright when cleaned and passed with flying colors, except the grey water tanks, which weren't too bad, and of course the holding tank
. A thirty year old stainless steel holding tank
is a big problem. It wasn't leaking yet, but there was visible pitting on the exterior at the lowest corner, and I felt it was a ticking time bomb in the bowels of my boat (yuck yuck). It had to go. So aside from the massive plumbing project
I will focus on just the holding tank rebuild
for a round of pics here.
I will warn you know that a few of the pics to follow are far from pretty, and may permanently mentally scar you if you view them. Some things can't be unseen. YOU HAVE BEEN WARNED!
