Oppon more reflection I'm think'in this may be an attempt to turn his boat into a Shannon 38 SRD. Shannon made mostly sailboats but ventured into the powerboat field w their SRD hull. SRD stands for Shannon Reverse Deadrise. I really like the SRD. I'm probably not correct because if I am this is a very bad attempt to emulate the SRD.

http://http://www.shannonyachts.com/shannon_srd_technology.html

Here you can see the concept. Brilliant I think. The fwd sections are almost pure sailboat and the aft sections are much like a powerboat. However most all powerboats (except the Hickman Sea Sled) have flat bottoms or bottoms w some to considerable deadrise. The SRD has reverse deadrise aft. Very unusual but it delivers a hull w a great deal of the characteristics of a full disp hull but w the ability to run 20 knots and quite efficiently as well. I think the SRD hull is truly amazing and I remember showing Walt (Seahouse) this boat 6 or so years ago.

Anyway the resemblance is there but .........................

Yes, I think it's a variation on the Shannon concept. It might perform admirably. I wonder if marinas charge for the 34' hull or the underwater length.

Palmer Johnson's latest thinking for lateral stability on hull design for their upcoming Super Sport mega yacht line...aft sponsons. ..

Yes, I've seen that photo before. An idea whose time has come. Add deck house out to the edge of the sponsons and you'd have the essence of the PJ. Bet we see it applied to more and more designs.

On that boat Skid I ran the bow line to the aft cockpit and stepped onto the float w both bow and stern lines in hand.

Basically the Easy Rider was a cross between a trimaran and a cathedral hull. A small duck could swim around each sponson and the center hull separately.

I was in Dixon Entrance w this boat in 20' seas ... a bit aft of the port beam. I stood on the inside of the stbd hull at times.

This is a PERFECT example of what I mentioned reading recently in another thread...namely the marketing phraseology of a boat being a "Pocket Mega Yacht." I think this boat should be the poster child of what a pocket mega yacht could/would be. Except this isn't a full size pocket- it's more like the watch pocket mega yacht.
FYI, this boat was just added to YW this month (april 2013).

Personally, like I said before, I like the idea. There's sooo many folks out there that don't have any imagination..."I want to keep it original." What a shame not to make your boat personal.

Same goes for the "resale" thing. I bought a high resale boat and I want to keep it that way - that's how I get the most enjoyment out of my stuff...by keeping the resale value high. Well, not all of us boaters subscribe to that outlook. Making it mine is much more important to me than keeping it original or keeping the resale value at maximum.

Could the design, ugly as it is, be for beaching, sitting on sand bars or something of the sort?

Brewer Deep River Marina continued ongoing restoration work on an Island Gypsy 32. “Last year we extended the boat’s cockpit and added a bulbous bow to increase boat speed,” says General Manager, Jim Brown. “These alterations turned a 10 knot trawler into an 11 to 13 knot trawler at cruising speed. This year we added a prop nozzle to further increase the engine’s efficiency.”

I'm thinking the guy just took up fibreglassing as a hobby, and really enjoyed it, so he just thought up a new project every year.

I picked up on that one right away as the bow of the Manatee was not in the center between the two hulls.

Walt it's a good thing you underlined DISagree as you like to say agree. Does that make you agreeable???
I don't know why but I have that pic in your avatar.

Yes, or Capt Nimo's Nautalis. Love them or hate them, the PJ designs are always cutting edge. We boat in the Sturgeon Bay area, and it is a jaw dropping experience to see any of the recent PJ sport yachts bearing down on you at 30 knots. By the way, if you look at the drawings of the bow of the Super Sport in the link or the photo below....the shape of the bulbous underwater section is not unlike the one on the subject 32' IG. (Still looks like a photoshop to me).

I'm closer to the "hate'um" category.

Skid do you actually like these things?

They look "bitch'in", "tough" and perhaps cool but they are a maze of arched lines weaving back and forth or up and down w splotches of dark masses in-between that resemble nothing in particular so lots of people won't even know it's a boat.

Perhaps they are hot rod boats styled after a flame job paint scheme. Things that have been styled to such a degree that they aren't even what they presume to be.

Nuts.

I was also reminded of Dave Geer's work in this arena, In fact Passagemaker mag just had an article on his 'special bottomed vessels in their May/June 2013 issue.


Here is another reference I found

Shoal Draft Boat - Knots and Boats

Sometimes all it takes to change the game are a few fans to speak up and say, 'hey, there is something great going on here.'

In last month's PassageMaker Magazine, Paul and Linda Bremer along with designer Dave Gerr recapped the success of Gerr's shoal draft boat - a 42' tunnel drive trawler that draws only 22". Yes, that's twenty-two inches. Officially, it's called a "Summer Kyle" design; an Ultrashoal Tunnel-Drive Motorcruiser. And, in case you were wondering, that's exactly the regal title it deserves.
