Eric, if a Hobie is a full displacement hull, the folks at Nordhvn are going to have to redo their website.

What is the difference between a full displacement and semi-displacement hull design? Essentially, the full displacement hull remains completely in the water at all speeds. It virtually "pushes" the water away from its bow. The water then travels down the length of the entire hull, finally leaving a wake behind the stern. This "bow wave" creates a resistance to the hull, from which it can never escape [/I]

They could use tweaking as there is so much more to hull design you guys havent begun to address.
Bakers reference to Hobie hulls is but a piece of the pie...but certainly a big one and just the picture IS a thousand words.
A Nordhavn marketing blurb hardly makes a convincing technical case, however I'm only here for the comedy anyway.

Actually, Nordhavn's full displacement marketing blurb is closer to the truth than any other boat builders blurb out there. They have backed it up with many hundreds of builds in the past 30 years. Their starting point was to do an update of Beebe's written work and run with it. Trivializing their contribution to safe blue water recreational cruising is off the mark, by far.
But, the beauty of the internet is those that want, can attempt to drag down. Not successful in any sense for this case.

So, does that mean that a boat builder who states physical reality with respect to hull design can't be trusted because you can buy their boat? Interesting perspective, Fish.
As distinct from the "pissing people off" contest. A clear winner there!What do you expect, we haven't determined who won the pissing contest yet?

Some people have great dificulty with things that can’t be positively identified and classified. This is one of those things.

A read of the voluminous Nordhavn website can prove illuminating, plus the hundreds of available pages of first hand blogs from world cruisers. Don't forget to browse their in house written and then published "update" to Beebe's Voyaging Under Power. Then direct your curiosities and questions to them in well thought out written correspondence that should elicit a cogent reply.
Delfin,
Boat builders are business people. Sure they hire engineers and designers but they have a lot to say that they don’t pass through the engineering department. And they are primarly in the business of selling boats. And the boat building business being what it is few have no worries about making money. So what boat builders have to say about boats may not be something to take to the bank.
But as I said it’s prolly the marketing dept talking so who cares?
The only Nordhavn that interests me is the 46.
So...
What is the definition of full displacement.
Is it a specific hull design? Where no matter the engine HP it will always stay within the FD formula. Hull Speed = 1.34 x √LWL
Or
Is is a boat with a limited hp power plant that can never exceed FD speeds based on the LWL? Even if that hull design with bigger engines would result in a boat that would exceed the formula!
Can you even describe a FD bottom?
It was such a simple question.
Seems the answer is somewhat along the lines of: "if you ask a hundred doctors..."
