Al,I had thought about building a hardtop for my Tsunami when I did the resto,but ended up going with a soft top.
I have to say after having a couple boats with real hardtops and real glass windows,I thought I would miss the hardtop,but I actually like the soft top just as much.I NEVER! take it down,it stays up all year.
When we're on the water we will sometimes either fold down,or remove the side curtains,if it's a stifilingly hot day.
#all the curtains are removable
#go with Strata glass for the ising glass,it is crystal clear(I didn't,wished I did)
#The arch goes great with the top.Mine is not attached to the canvas
#I had a custom arch made by Atlantic Towers with six launchers(have since added 6 more)
#the arch cost me $1,800.00 very good quality 1.90" od.
I had the top and other canvas made from Seamark Sunbrella,which is regular Sunbrella with a vinyl coating on the inner side.It is completely waterproof and very strong.
It's been up for five years now,with no deterioration of any kind.
I had the top,-side curtains,-rear drop curtain with zippered door,and an aft curtain that runs from the top to the transom,made by a local guy who is a fireman but does canvas out of his house.He's been doing it for years and is very good and very reasonably priced.All of it cost me a bit under $1,500.00
Here's some pics,(in no particular order)hope it's some help.
