It looks fairly bad but the photo makes it difficult to tell. If it is as bad as it looks then I would soda blast to the gel coat and look for blisters. If no blisters found the barrier coat and bottom paint. If blisters then fix them, then barrier coat and paint. Sanding to bare gel coat would be a horrible chore and huge mess. Hire the bottom blasted and then DIY the paint if you want to. Our will let you do most any work EXCEPT sanding bottom paint.
Hard to really tell from one fuzzy picture, but it looks pretty normal from here. Might be a bit thick, again, hard to tell from this picture.
Usual method would be power wash, vacuum sand and bottom paint. Finding defects usually happens when sanding, so remedy as needed.
Maybe as a guide for the lifting strap, it has to be forward of the string? Put it aft and it will bend the rudder shoe. Is this a Grand Banks? I read on another forum that they used round head screws in the rub rail at the strap points, all the others are flat heads. Hardly anyone knows about that, including the Travel Lift operators. They have to have some kind of a guide.

I'll differ from Comodave (which means I am probably wrong). Bottom does not look awful. I look for 'paint sickness' where the old paint has sloughed-off and painted over. There comes a point where the layers of old paint need to be removed. Could be the picture is bad, but I don't see that here.
Why do you ask? Are you the owner and concered about a quote from a yard? Or are you a buyer or seller?
No idea why the string is there. I've never seen something like that so deem it inconsequential.

The string is most likely polyester cord strapping. It is used to hold shrink wrap down. There is snow on the ground in the OP's picture. It's is highly likely that boat is shrinkwrapped.
If you are going to do a barrier coat then all the bottom paint should be removed. Sanding it all off is a miserable and messy job. I just pay to have it soda blasted and then do the barrier coat. It will cost $1,845 to blast the bottom to the gel coat on my 41, well worth it.
