Chum had exactly the same thing on a Broom 33.
He remove the old sealing and resealed with CT1.

This brings back memories!!!
I did this on my 27 footer.. Believe the original sealant is something called Raliseal. It is cold mixed in a tub.. Unfortunately it comes in drums and not really suitable for the DIYer.
I removed all the cracked sealant but I was left with a large gap over 25mm x 15mm – that’s a lot of sealant tubes. I used over a dozen.
Mine wasn’t structural so I used Caulking Cotton twisted together and put into the gap to “fill” with the first “run” of sealant. Then I smoothed off the finished layer with sealant tools.

Take a screwdriver, sharpen the end and bend at 90 degrees..... to rake out the worst of the crumbly stuff.
I use Screwfix Nemesis seal & grab but it seems to be no longer available.... CT1 or equivalent, NOT silicone.
Squirt into the gap and build it up, scrape flush and then finish with a wet finger or sealant tool to give a smooth finish.
NOTE: retain the drainage slots, they are supposed to be there, otherwise excess water will flow into the boat and mark the upholstery (dont ask how I know!)
Used about a dozen tubes on 31' boat
