Absolutely right. *

Some sort of sturdy cabin closure is also a good idea, perhaps like
the drop boards in a sailboat companionway, with sliding bolts to hold
them in place. * You might be able to survive a capsize with something
like that.

Does not like either scuppers or low/no transoms. *He prefers
duplicate battery systems and large multiple bilge pumps.

On a new boat I build, I will probably go with:

Very high splashwell, no scuppers, a removable deck with foam
underneath, largest bilge pumps I can get with oversize hose exiting
as high on transom as possible thru smooth hose and 3 batteries. I
will incorporate a 8" bridge deck I will have to step over to get into
the cabin with removable hatchboards similar to hatchboards on a
sailboat.

On the existing Tolman, I will get the largest bilgepump (This will
give me two pumps) I can exiting thru transom up high. I already have
two batteries. I will install addtl floatation of foam blocks under
the leaning post and between stringers forward of leaning post.
Splashwell is already high but I may increase it by another 1.5".
