    I agree that it is looking a little strange, but the D29 is a "sidewalk" with the cabin off center, but the boat as such is in balance...:)

    As it has an IPS-drive in the center, the deadrise there is zero. Besides this it is different from most other hulls, exactly how, I can not tell at this point.

    In front of the drives, the deadrise goes from 90 degrees to zero.

    Our main reason to go with IPS is that we are a Swedish brand and like to use Swedish engines. So the hull was purpose designed for IPS.

    Lars,

    IPS - i was expecting something a little more technical, but ill pay that.

    deadrise - i was just having a look at your D29 and it looks like it's running around 20-25degs...? and was interested in the larger boat (54) if u have gone with less or the same angle. they are both sitting very nicely when running.... Very Nicely!

    hope the boats going well, cheers

    This year is soon coming to an end and the same goes for this thread. It has been a busy year for me and I have not been posting much news here, but soon I can show the final arrangement of this 54-footer. Meanwhile, here is a picture from when we tested out the hull, with the deck now superimposed..:)

    This is the General Arrangement of the D54 as now decided on. The aft deck is on the same level as the aft part of the saloon, with the forward area a step up. Down below are two twinbedded guest cabins and a master with a double bed and there are two bathrooms. Pretty straightforward layout.

    All is built with light-weight materials, on teak laid carbon decks. Plugs for the superstructure is now under construction and all will come together piece by piece during the spring...

    Well not exactly, this is an escape hatch in the master cabin and a hatch to the forward storage, with a skylight in between...

    Oh I see, but you can see why it conjured WallyPower 118 though Lars?

    The flush hatches look good from them, no doubt it'll look great on the 54. This is the way to go, of course this is where the industry has gone, for quite a few years now. Raised hatches seem to be a thing of the past now.

    Conservatism

    Having lived and worked in Sweden I know that many Scandinavian boats have forward leaning windows, so its a theme that works there.

    In many other parts of the world there are similar 'standard' appearances. In Southern Europe the stiletto-nosed yacht is king, in the US its the sports-fisher or the trawler.

    Many boatbuilders address the middle market in their own regions, and very very few buyers are adventurous.

    Here in the UK its very difficult to tell which of the builders has produced a motor yacht, they all look similar, and are meant to not frighten the buyers, most of whom are middle-of-the-roaders.

    To strike out into a different market takes insight, certainty and huge, huge courage.

    If the Wally boats, which terrify many, succeed, they do so by appealing to the minority, perhaps 10%. The style conscious are always a small minority, thats a given. 80% of people are deeply traditional, and the remainder are enthusiast for historic design.

    It make good business sense to stick with the middle rump of the market, except that this is where all your competitors have also set up camp. Its possible to make a good living there, but also in more adventurous product development, providing you have the aptitude, enthusiasm and skills to sell against the norm.

    I thoroughly admire the way that you have built up your company and fleet. Its very encouraging, and especially when you suggest that serendipity played such a part in the hull form and effectiveness. It should encourage us all to dive in with both feet.

    By the way, as an architect, I caution against designing by committee. Its lovely for us to see what you are developing, but bear in mind your customers, not the people who review designs on websites.

    The advice you get may come from people who may never buy your boats, but might steer you away from what makes your boats attractive to your buyers.

    Thanks Michael,

    You are right about designing by committee. Fortunately we are just three people taking all decisions, the head of sales, the production manager and myself. But of course we also check with the market, especially our own clients who appreciate our present style and qualities.

    The problems I face with the 54 is that people expect a lot of equipment in this size, that will make her more complex and heavy. Like dishwasher, icemaker and a huge tenderlift at the transom...

    Taking the Kitchen with You

    Yes, we all expect more 'things' with us. I'm refitting the boat I bought 20 years ago and find myself adding things that weren't available then, but are now seemingly essential, like internet receivers, flat screen TV, and low energy lights. Plus the extra batteries needed.

    None of them weigh nothing. So thats why a big boat is now 75 feet not 50, and why my friends in Sweden who told me not to buy anything over 32 feet long because it wasn't 'normal' have bought bigger themselves.

    But you have space on the 75, which from the illustration looks practically ready to build. If you can convert to a low speed, low wash hull with these bigger boats you can surely have space for the extras.

    I agree entirely with you that doing 30 knots in the narrow channels between the islands around Marstrand in such a boat would be utter madness. So perhaps 10knots is the new sensible speed of boating?

    Even Wally is embracing displacement hulls now.

    I like a later version of the 75 better than the one you posted; http://www.yachtforums.com/forums/62478-post145.html

    Anyway, what you get with a boat this size is two full decks, on the 54 we still have to consider where standing height can be obtained on the lower deck.

    When we tested the 54 hull, she performed well in all speeds, the hump speed was between 15 and 20 knots, never with more than 3 degrees trim and between 30 and 40 knots, she stayed at 1,5 degrees trim. At ten knots, (1250 rpm) she had a 1,5 degree trim as well which means very little wash.

    On the topic of bow and transom angles, I was playing with the old 33 m Silver Bullet (top) to see how she would look if following the fashion...

    This comparison is interesting. Changing 'only' the bow angle can have great effects, but the impact on real hull in 3D may be difficult to design.... :confused: Would you try ?
