Azek is a composite material used for exterior trim,doesn't rot or absorb water,and its white,it is similar if not the same material as the amish outfitter boards. yes it floats,but not as bouyant as cedar which allows it to sit deeper in the water [more board in water = harder pulling board] the added S.S. makes it sit even lower and keeps them bottom heavy which helps to prevent them from rolling over in rough waters.This is at least the fourth design [if you want to call it that] that I have built and so far the best. I've tried as you mentioned not having the boards parallel which didn't make them pull any harder only made them run further back, also tried a rudder as I've seen on other boards and got the same results.

I have a pond out back and have tried many modifications using the 4 wheeler to pull with a spring scale in line. what I have found that effects them the most is the location of the eyebolt and how deep they sit in the water.


These boards pull hard!!! I don't think they could safely be pulled by a mast. I pull them off my hardtop,you can hardly pull them in without steering towards them.I also use the 500# spectra w/ snubbers as someone else mentioned.
I'm real pleased with this set-up
Feel free to ask any questions as I've tried alot of different things
