Re: 1985 Wellcraft 210 Elite Restoration
The pros and cons of floatation foam is a very unbalanced discussion, as I see many more benefits to installing the floatation than I see pitfalls.
Pros
#1. It could save your life and the lives of your passengers... just this one benefit outweighs all of the pitfalls added together and then multiplied by 10.
#2. Your boat won't sink to the bottom of the lake if there's an accident or emergency.
#3. Floatation will give you additional support for your hull and deck making it stronger.
#4. Floatation foam seals the inside of your hull in case of a breach... if you knock a hole in your hull by hitting a partially submerged log the foam will block the hole off from the inside and your boat won't take on water and you'll be able to get yourself and your passengers back to the launch without sinking.
#5. Boats that sink to the bottom leave the owner liable for EPA pollution fines from spilled gas and oil, these fine can be hefty in certain areas and they include the cost of cleaning up the spill.
#6. Your boat will be quieter on the water, floatation foam is a sound attenuation product.
Cons
#1. If you neglect your boat and leave it exposed to the elements (like you're really going to do that after all of the hard work you've put into it) your foam can become saturated/waterlogged adding weight to your boat and promoting rot below deck... but, it takes a long time for floatation foam to saturate... were talking about a period of years of constant exposure.
End of cons.
I personally would never own a boat without floatation foam, and if I bought one that didn't have it I would install i myself.
Todays boats that're built with an abundance of floatation foam float like this:

Yeah, I know that's an aluminum boat and yours is f'glass... but they build a lot of f'glass boats that float like that too. Boston Whaler, Key West, and a bunch more.
The older aluminum and f'glass boats that were just built with the bare minimum of floatation to keep it afloat float(ed) ike this:
