chardel,
According to a quote by the factory in this post, the gelcoat added about 215 pounds.
I see several new ATF posts by you today. Please make good use of the search tool in your endeavor to seek your answers.
As for benefits of the gelcoat option, I believe the primary benefits to be:
- A smoother appearance. No fibers are visible
- Ease of cleaning and this one is debatable
It's a nice feature but it is not always a "must have" for people. If your budget is tight, this may be a pass for you. I have it on mine and enjoy the ease of caring for it but I doubt the non-gelcoat is much harder to clean
Best of luck to you on your research,
Jim
