the boat in the original post looks older, with a fair amount of oxidation.
In this case, if you want a repair that will be less noticeable use Marine Tex.
Smooth the area as best you can by laying wax paper over it, before it sets.
You'll have a good 10 footer (on a white boat anyway)
Please note this is IF you do not try to sand the patch smooth. If you do sand you'll end up with a very noticeable spot.
If visually noticing the repair is not important, but a resultant smooth surface is, I'd use Formula 27.
The curing process is much quicker. You can sand it baby butt smooth and go sailing the same day.

These two are the only permanent methods I'd use for such a small repair.
Exception being if a long term plan is to re-gelcoat the entire boat, then I'd consider poly resin, in lieu of F27.

Former hobie admiral tip
Place plastic wrap over the marine tex repair it will save most or all sanding needed
another one is to smear MT on the wear area on the bottom of the hulls and rudders and centerboards
Do not really understand the Marine Tex haters
The stuff has kept me on the water sailing
Some of my repairs have lasted 25 years and is still going strong
Marine Tex is always in my Hobie Hell Box
Epoxy hater here Gary, I'd rather be sailing than sanding
