| Another thing to consider about V bottom and round bottom hulls is the value of the bilge space.   A flat bottom offers little or no useful space in the bilge for tankage, and other stowage....

What horse crap! If you see huge value in a bilge, add a fake one. It is hella cheaper to add a removable floor to an easy to build cheap and light hull.

| This is not insignificant, as deep down is the ideal location for such thing as liquids and batteries, and other heavy stuff.  Built in tankage is also insurance if you run onto a coral head, and rip into the bottom......

Ya, all the guys checking the latest boats are all checking out the critically important BILGE volume.

| it can prevent the main hull(s) from flooding.  The entire bilge in a Deep V or round bottom hull could be sealed, with watertight access ports, and ideally each bulkhead would make a separate compartment without any connection to the adjacent compartments.

I don't know any sailors looking for water tight bilge as a safety feature. But, perhaps I can learn a thing. I would imagine the crush zones on the HP would take the hit fine. And are probably are considered by most as a kind of belts and suspenders protection, but I don't know

Does any list reader care to instruct me in the value of a water tight bilge?
