Our Voyage 380 came with a targa bar and it is one of the best features of the boat. It increases our useable cockpit
space by raising the the travel up from the cockpit
a putting it over our heads. We have also mounted our solar panels
to it and the top of the bimini
. The panels
don't look like they were added on as an after thought and we didn't need to build a seperate structure for them.
Because of the combined strenght of the bimini
and targa bar the builder
put a cat walk up on top. I can access my sails
without having to climb dangerously above the deck
and it puts my eyes 15 feet above the water
. The view is great and have used it as a look down when entering strange harbors.
I don't think I would make one out of PVC unless you were just trying it the design and style out. PVC is strong enough to last or provide and real structural strength.
