    Other than speed, you're describing an Allweather 26

    So since the Allweather 26 does not fit his requirements, what does?

    The Allweather layout with a squared flatter stern rather than double ender and more of a semi disp. hull shape ...the weather sorta determines your speed anyway, not gonna be comfortable in under 30' boat in slop at 15 knots...
    Also better rethink not having a "cup" holder" sure saves on the spilt beers/coffee...

    hmmm.

    I posted earlier with skepticism. However, since then an idea has come to mind. I used to have a Wellcraft Airslot and loved the way it would catch air over 30mph and lift the hull to where only the very fine entry at the bow was hitting the waves. It was something like this but more primitive:

    So, here's my idea: If you make the sponsons on the sides much larger...with torpedo shaped bottoms.(use bulbous bow models) Then, you have to make the hull itself really dedicated to trapping air. So, at speed the hull really wants to keep a cushion of air between itself and the next wave.

    Lastly, and this is the trick, you have to design the sponsons to move independently of the hull. In other words, the sponsons become like the suspension of a car. The sponsons hit the waves like your tires, a suspension system attaching them to the hull takes the bulk of the shock and the hull does its best to stay above the waves on a cushion of air. The hull could still grab the water in turns and at slower speeds - so it wouldn't handle like the cat-hulls I detest. Stick an Arneson surface drive with a long shaft on that baby and haul ***.

    The "Airslot" design is really being taken to extremes now:

    However, I've yet to see one with a suspension system.

    I wish I knew how to draw many of the weird ideas I get from time to time. But my degree is in finance...not engineering. So, I hope one of you can run with it.

    Being a european I am always amazed at what americans call "european styling". Most times it seems to refer to a sort of style that a certain type of americans thinks are "stylish" and especially "sophisticated". The thing is, that that sort of styling have very little bearing on anything in the real Europe. Glossy man-bags, for instance. Huge ginpalaces in the Med and so forth. Caps and "european" shorts on 60-yo men etc. You can always tell when it's an american walking around being "european".

    :p

    Sorry to be off-topic, carry on :p

    What makes/models of cats have you been on and what did you detest?

    cats

    I've been on most of the smaller ones and, to be concise, in big seas I'd be terrified at speed. I don't like the way the lean in turns either. Most recently I joined a friend on his 48' Ameri?? (forgot name - help) to the Bahamas. It was rough across the Gulfstream and the boat just handled funny. It shuddered and wiggled and then would bang when a wave would smack up underneath.
    I think we would have been much more comfortable in a flatter bottom regular hull with a very sharp entry. We would have had a lot more room that way too!

    An off topic may need an off topic reply. Who knows what anyone means by a statement of style or taste?

    However, it is true that the current styling trend in boats to make them look more like Nike running shoes did come from Europe. A poor choice of imports in my opinion. Opinions are personal, but there it is:D

    Hi, Tony,

    This was posted in another thread recently. Called WAM-V Proteus. Different from the Airslot concept, but a sponson design with suspension system.

    Haha, okay. But who's to say, that those european companies are even styling it "european"? Perhaps they styled it that way so they could it sell it to the manbag-carrying "sophisticated" americans? Not to the rest of us, europeans as well as americans.

    Anyhow, I didn't mean to hi-jack anything, it just seemed that most things with the "european" design is mostly sold in the US (and to the newly rich russians, for that matter). That means – to me – that it isn't really something particularly european, but a style labeled as "european" because in that label there are some connotations of "sophistication", "stylish" "Old World", "tried and true" and so forth. But in the end, it seems to have been overeploited as a marketing tool. So much so, that it has little bearing on the real Europe.

    If that makes sense …

    Don't go there.

    What you are proposing is something mid way between a rider-less surf board and a mini-sub. The hull form that would promote the speeds you require is not the same hull form that is proper for heavy seas. That is until you reach OAL of 50+ feet.

    Planing in high seas is a death wish, or somthing close. Lot's of fun, but with dire consequences when the rudder ventilates. To plane a 26' boat requires a flat bottom and lots of sail area.

    To break through 12'+ waves requires a slim narrow entry with water tight hatches and ports. Not too much sail given a proper angle to the wind.

    The "EURO styling" seems to be on domestic built cheapos where dockside VOLUME is the prime concern.

    Hinkley and Hood don't build Nikes ,

    but Bayliner , Carver , Sea Ray turn them out by the gross.

    Gross Blob boats! At least they have little longevity , so are soon gone.

    Exactly that was my point, FF!
