Hello,
I'm refurbishing a new to me O'day 22. On the topside there is this non-skid surface. As you can see it's in pretty bad shape. Should I strip this off and replace it? If so, how? What is this surface called so I can do more research?

The nonskid is just molded gelcoat, same as the rest of the boat, just tinted.

Over time the nonskid wears as you are now aware of. There is a tedious way to renew the nonskid with gelcoat and special molds. I wouldn't waste my time on that project.

There are paint additives that provide a non-skid surface with much less work and expense. Andy Miller on the YouTube channel BoatworksToday has several videos on how to apply new nonskid.

The short and simple method is to sand off the existing nonskid gelcoat to get a clean flush surface. Apply primer (if necessary) and paint. While the paint is still wet sprinkle the nonskid product on the wet paint. Repeat this and then paint over with the final coat.

Another alternative is to sand the nonskid off and glue a nonskid flooring to the deck. Probably less work but more expensive.

Hi Dr
RE; What is this surface called so I can do more research?
The deck is manufactured in a "female" mold. In the mold there is a raised pattern, usually little pyramids.
This pattern is then transferred to the deck. So it would be called a molded anti-slip deck or surface.

RE; As you can see it's in pretty bad shape.
Over time the tops of the little pyramids wear off. That is where you are now.

RE; Should I strip this off and replace it? If so, how?
This is part of the deck and can't be "stripped". It can be ground back, but there is no real advantage it that.
As Dave has mentioned there are paints.
Your process will be.
Wire wheel the surface to clean and scour the small valleys.
Clean down with a solvent like acetone.
Prime.

Then make a decision on how much time and money you want to spend.
Here are you options.
Paint and non-slip added before paint is dry. Easy quick reasonably cheap.
A proper non-slip treatment like KiwiGrip. More complex and more expensive that paint but a proven finish.
Non-slip pads like on stand up paddle boards. Easy, cheap, soft on the butt, funky patterns. Not long lasting.
Non-slip tape. Effective (if you like sitting on sandpaper) very cheap ad easy. I have tape on one of my hatchtops and it does the job.

I went with kiwi grip. Made the boat look brand new. Solved a lot of issues (like the tiny cracks on the surface) easy application makes it a good diy project. A boat your size, should only require a gallon of the stuff... make sure you shop around...I found an online chandlery selling it for about $110/gal. I chose light blue....looks so good. I like the "buff" color and the light gray. The prep is pretty simple and quick. NO power sanding needed.. I used a bristle brush and the recommended cleaner... The product is water base, so clean up is a snap. Most time consuming part is taping. A razor blade or exacto knife to smooth the corners... The razor blade worked best for me...I practiced trimming the tape and experimented with the applicator to determine how aggressive I wanted the surface.

We went with the kiwi grip as well with great results.
Clean the surface well (as stated above there is no need to sand off the old surface. Wire wheel and solvent cleaned), tape the area off and apply.
I will say that we found going heavier than you initially think with the kiwi grip is better. You do not want a thin coat. The roller needs material to pull up to create the non-skid texture.

Total Boat nonskid paint, mix of white & sand color, works well enough, same diamond pattern, has grit in paint, although I added a bit more, goes on easy. This is one coat.
