to the grounding/drying out issue was this. Boats and bottoms shouldn't touch unless they're small boats. I could not seriously consider intentionally putting my 'multiple hundreds of thousands 'of dollars boat on the ground. Besides, sand messes up my bottom paint job! Seriously, taking the ground is only something I'd want to have the capability for on a voyaging boat to areas where haul outs for maintenance and repairs aren't available. Shoal draft and engine/rudder/daggerboard redundancy are a nice benny of a multihull even if you can't beach it.
