Removing Counter Top In Tri-cabin

[k9th]

SeaDog was hauled out yesterday for the winter and, as a winter project, I want to replace the counter top in the galley. I am going to the marina this weekend to try to remove the old counter top and hopefully use it as a template for the new one to make sure the fit is precise.

Does anyone know how it is attached and how big of a project that is? Any special tools I should take with me? The built-in stove has already been removed, but the sink is still in-place.

I am not a wood worker at all but my brother-in-law is and he is going to help with the project but he can't come to the marina with me so I will be removing it on my own.

Any help would be greatly appreciated.
