Bottom Paint - need advice

Lets start out with what model/year, where you are docked/located,  salt or fresh water, hours on engine , if wet docked since new,etc.
From your pictures you definitely need both a bottom cleaning and continue using bottom paint, whether ablative or not. After bottom pressure washed/cleaned let a expert determine if you need re application and what type needed based on what is currently applied. 
Attached are two pictures  of our 2001 4160, 900 hours continuously wet docked since new in 2001 on Lake Lanier GA. The original bottom paint is pristeen, never had cleaned or re painted. 

I thought I read something somewhere that you could re-gel/restore a hull after removing bottom paint but I think it’s super expensive.

Thanks for the detailed info and Your welcome for the pictures. Bottom Doesn't look good with only 50 hours on a 2019 boat , the bottom is in need of cleaning as shown in your pictures! I have a rough idea that the original owner was advised to get bottom paint when he bought it based on the lake/river it would be kept om/in? I dont believe I mentioned the bottom paint can not be removed? If I was you , just have the bottom pressure cleaned before storing it dry over winter, take a couple of pictures after pressure washing and talk with a professional about removing or re painting bottom. My oldest son (50, has a 38 Sea Ray on Percy Priest lake outside of nashville. All the folks on that lake wet year round need bottoms pressure washed at least once a year, some twice! Nasty water they are on (like Yoda would say).  

So your walking away because of the bottom paint? had to be something else negative (price!)? That 2019 model year vessel with only 50 hours on engines most likely still under factory warranty? Well, good that you posted you questions before committing to purchasing it. Question, the dry dock pictures were taken by you or current owner? Looks like snow on the ground so most likely current owner has had it pulled for winter and on blocks so no trailer?  

Correct about the snow location...actually outside of Chicago. Glad that I received some good comments that convinced me to continue my search. Actually I'm pricing out a new build 26 XO between two dealers. It will be exciting since I'll be able to visit Regal in Orlando to see the boat at a specific manufacturing stage.

My thoughts on Bottom Paint=
 I dont believe bottom paint is a mark against any boat, regardless of how old it is, size, where docked (wet or dry) etc. To me the original owner had the insight (or was recommended) to have this important protective measure done due to location/wet or dry docked/condition of the water boat will be used/stored in/or on. The condition of our 2001 originally bottom painted 4160 being wet in the lake for 19 years is a testament to the positive effect of bottom paint regardless of where you are.
PS: Still not sure why OP walked away from it, cant believe the fact that it was bottom painted was the reason? OP, if I may ask,what was the asking price and what kind of numbers are you getting on a brand new equivalent?  . 

Thanks

tomj, thanks for the reply. Yes, the difference in price is worth buying a brand new vessel! Assume the price includes a trailer?
My middle son (39) ran into the same problem with a new 24' tri toon pontoon boat (150 HP Honda on it, full canvas, trailering cover, etc.) . New boats (with trailer) were only about 10% more than a one or two year old one without trailer! Interesting how the new/used boating market works?
