In the Hunter 37.5 I just closed on, I discovered that the holding tank has a crack about 13' long at the seam connecting the top edge with the side panel, allowing effluent to exit. A Raritan tech told me that the tanks (plastic) can be "patched", but they do not sell materials for the job, nor suggest the process. Is anyone familiar with the process of patching a plastic holding tank?
Patching "plastic" holding tank in place

That is a difficult 'fix". There are plastic "welders" http://www.harborfreight.com/catalogsearch/result?q=plastic+weld
that can be used but welding plastic is an art form .. I wouldn't trust a patch and would probably replace the tank .. If you are set on patching, have the crack welded and then cover that with another patch welded over the original crack.. (like using an angle shaped piece (to go over the top edge) about 2" longer than patch welded over the area.

The tanks are just not that expensive. I would also suggest that you replace it. If your boat is like the H35 you have a lot of room in the starboard lazarette so you have many choices on the size and placement of the tank.

I have found that a 45 watt soldering iron can do an emergency patch.
Go down the crack melting plastic on each side and moving it toward the crack. Go over the crack again to smooth. Try to get at least 1/2 the wall thickness melted all along the crack.
Good luck

Seriously bad idea
You're out in a good 15 knot breeze.
Boat is clipping along at 7 knots at a 20 degree heel
A few guests on board.
Someone goes below to use the head.
And you start to notice a really bad smell from down below.
Just replace the tank. Its not worth the "downside risk"
I can just imagine the scenario

Had a crack in our holding tank around the flange and was able to purchase one though this site cheaper than going to the manufacture. I was thinking of trying to repair but the Admiral insisted on a new one since you can't be sure the weld would hold.
