Hi All,

I am adding saddle tanks to Jodie B.

Im not 100% sure what to do with regards to the vent plumbing.  I would
like to ask if anyone has any advice?

I am thinking of putting 2x through hulls on the top of the main pressure
hull.  For and aft of the tower and then piping the vents to a valve that
would operate through them.  Similar to the existing vents.

OR, fit the through hulls at the side so they penetrate the tanks and have
a linkage of some sort that operates valves attached to the top of each
tank, for and aft.  Some sort of mushroom valve??

Any ideas?  What have other people done?
