I don't remember the dimentions for sure, but I'm not sure they would all be exactly the same, you need to wait until you get the stringets in your boat then measure it to be sure.
Hey there Red, got home and been thinking of getting back working on my scimitar. It totally slipped my mind by my dad has a good friend that runs a place that manufactures aluminum booms for spray rigs. I gave him a call today and he is supposed to come out and look at my boat and see if he thinks he can make a tank like the one you put in Geary's boat But out of aluminum . Do you recall the measurements, or have something for a pattern?
