The the water inlet spigots on both of my water tanks have been over tightened resulting in multiple splits in the threaded collar of the tank. I believe the fix would be to:
Does anyone have a better idea? If so, I am all ears.

Randy,
It may be more cost-effective to replace the tanks through the INA program for the amount of effort you’ll put into that.

If you plan you plan to keep that tank, the first thing you need to do us drill a hole where the crank ends. This will prevent the crack from spreading.

[/details]Randy,
It is interesting. The tank does not look like either of the water tanks in La Reina. La Reina is hull 68 so it is possible there was a change in the takes from hull #37 . Where the water outlet appears to be at the bottom of the tank it looks like you have a 1 1/2” opening. La Reina has a 5/8” barn fitting. La Reina,S tanks have two inspection ports, each located about a third of the distance from each end.
From the photo I can’t tell if the cracks go beyond the threaded collar into the tank itself. If they do you are going to have to follow Joe’s advice to stop the cracks from spreading. If you can do the work yourself it might be worth trying to fix. If you need to pay someone else consider replacement. Even if they are fixed they will still be 38 year old brittle plastic tanks.

Hi Bob,
I looked at the water tank replacement page. Am I correct that the tanks are $430 dollars each? Is that price in U.S. or Canadian Dollars?

Hi Randy - for the 26C there is just one tank. 30 gal and it is $455 USD.
Let me know if you have any other questions.
Regards,
The sad part is the price is in big U.S. dollars but small U.S. gallons. The tank is only about 25 real gallons (Imperial) 
. The good news is a Nonsuch 26 carries more fresh water than a lot of new bigger boats.
For example a Dufour 310 carries 42 U.S. gallons vs 60 for a Nonsuch 26 Classic.
Because I am full of it, I always check holding tank capacity. Most of the sales information on new board does not include holding tank size because the numbers don’t look good: Nonsuch 26 - 25 U.S. gallons - Dufour 310 (drum roll please) 5.3 U.S. gallons. Does not take many beer to fill that baby.

Randy -
It’s a water tank - it’s old and it’s brittle. I wouldn’t bother - I’d replace it with something really good.
Here is an option: https://www.imtra.com/products/other-products/nauta-flexible-tanks?productid=26756&producttypeid=508&filterBrand%2FCategory=Nauta+Flexible+Tanks
Utterly flexible and indestructable, a Nauta bladder-type tank installs in a jiffy. It imparts no taste to the water. This one is 35 US gallons and it should fit fine. These are the highest quality bladder tanks built. Plastimo tanks are good - these are better. They are used in US Coast Guard cutters and hi-speed patrol boats for everything from holdingg tanks to diesel tanks to water tanks. The factory sells this one for $485.00 US but it’s likely available for less.
I have a smaller one onboard my NS22. It’s a holding tank. Absolutely no smell, etc. and it’s six years old. It will outlast the boat (and me).

Bob,
I assume you mean there is just one tank size/model for the 26C. However the 26C has 2 tanks which are identical but the one on the starboard side is placed with the fill and vent towards the stern. The identical tank on the port side is turned so the fill and vent are towards the bow.

Yes, thanks for the clarification. One style tank.
