From a maintenance standpoint, gel coat is much easier to repair as opposed to imron paint which would require the entire boat to be re-painted. Simple scuffs and scratched could be easily buffed out on a gel coat.

That product is not durable enough.

Depends on the size. The one shown here would not be. I have this model in the 22 vs 23 ft size. Open bow boats (bowriders) aren't a good choice for oceans. You would need a really high fretboard to offset the risk of taking water over the bow. Some large Cobalt "R" and "A" models would be OK.
