Default Flybridge - Replace bimini with hard top - thoughts?

Has anyone replaced their flybridge bimini with a hardtop?

We'd like to go hardtop and have "fold/hinge up to overhead" plexiglass windows vice our current unzip/roll up isinglass. We'd add windshield wipers to at least the forward window(s).

We certainly don't need anything fancy like a tinted moonroof, or sliding sunroof, but it would be interesting to hear if anyone has those too.

Thanks in advance.

I have seen custom tops installed on boats like yours. A local fiberglass shop can provide a quote.

Note with a hard top it will be fixed so if you have low bridges this may be an issue.

An acquaintance from a marina we used to be in has installed one on his 40ft Silverton aft-cabin. I recall it being about $20K installed 10 years ago. There are many fabricators and installers out there and quality will vary. I have never priced it myself.

I wouldn't install plexi. They make thicker mil of Isinglass. Some so thick it looks like glass when tight and can't be rolled. You can still undue the bottom snaps/toggles and put some toggles in the ceiling to snap it up and out of the way, as you were describing.

Thanks for the replies ... Between cost and the issue of weight above the CG, I think we're just going to stay with the bimini. Need to figure out a good way to take a 'droop' out of one area between two frames - it sagged due to heavy rain when we weren't around. Anyone know of a 'tightening' method (preferably a permanent one)?

Is the top tightened with vertical straps or framing? If properly 'tuned' you should be able to bounce a ball off of your Bimini. I've frequently seen installs where there simply isn't adequate support. You need tension in different directions.

The top has athwartship framing about three feet apart in the area of the drooping. I can't see how to 'tighten' this area as the bimini has zippered 'tunnels' that attach it to the athwartship framing supports. The area was always taught before, but as I mentioned earlier, there was a period of heavy rain - week and a half - during which time we were unable to get to the boat. It's during this time water built up enough to weigh down the bimini and cause what is now, seemingly, a permanent droop.
