Joel,
My sketch plan is not to scale but yes...it is an acurate tank location. I can get some measurements for you if youd like. There is also an oil tank mounted in the bilge aft of the tank.
Like Bigshrimpin said the boat performs very nice. An Etec on the back would make it perfect

. I cant take credit for the layout as it was copied from Strick's 23 and various Hermco re-habs

I just chose a smaller tank for my use.
