Fiberglass.  Just glass one in place in a void in the
bow under the master birth.  My bow thruster tube
rests right on top of the holding tank.  The holding
tank also serves as a collision bulkhead at the bow. 
If you punch a hole in the holding tank, the hull is
still water tight.

Mine is 75g. and works great for the two of us.

A couple of other things.  

I do have an overboard discharge for the holding tank
but always pump out at least three miles off shore.  I
do not have the ability to flush directly overboard. 
Everything goes into the holding tank and I have to
manually flip a holding tank pump switch to pump the
tank.  No possibility of an "accident" in that case.

Since I have a watermaker and a 300g. stainless steel
water tank, I use only fresh water to flush the head
even though I have the ability for a salt water flush.
