Standing headroom means more windage and / or more slamming because there's not enough clearance between the bridgedeck and the water
I'm 6' 2". In my Iroquois I could stand in the hulls but was on hands and knees in the saloon
or waddling between hulls in an undignified and highlu unflattering crouch. It was a delightful boat
to sail and I could bring her alongside in most conditions using a single
The Piana 30, my current
boat, has standing headroom through most of the hulls, stooping headroom in the saloon walkway and sitting headroom at the table. It does snag the incautious toe on the bulkheads though. It is a fun boat to sail, a bit more windage than the Iroquois, a lot faster, but despite twin outboards it's more of a handful to dock
in tight quarters.
My next boat, the PF Lucia, has standing headroom throughout. It has a lot more windage. It also has two big inboard diesel
engines. That might be enough but some folks have gone as far as fitting bowthrusters on big windage cats. It will cost a lot ore in the Marina and to lift
The cost of comfort is extraordinary. The next boat will finish up costing thirty times more than the Iroquois. It's a lot. In his book "Multihull Voyaging" Tom Firth Jones stated that the only time he needed standing headroom was when he put his trousers on.
Were I not planning on enjoying the company of guests that expect more comfort and the ability to walk from hull
as if they were in a hotel
I'd probably update the current
boat. I did consider keeping the one I have and chartering a bigger cat when friends and family
came to call. Still might! :-)
So: - If you want the freedom to walk about your boat without ducking your head
be prepared to spend a lot of money
unless you are either prepared to seriously compromise on handling or performance.
