    OK, I was talking to the guy who is responsible for IPS at Volvo Penta Sweden and he said I could not use 22°. He also said that it increased the risk of cavitation damage to the IPS as they are sucking air from the sides. So my conclusion is that they have used them on such boats and the experience is that they will not recommend it.

    A second problem is that they don´t have props for higher speeds than 43 knots, and I want for 50 knots. Perhaps they have for the petrol version, but not for the diesels...

    Sorry, no. I have not been following the IPS scene all that closely. But the boat in that link I provided is the same SeaVee model that Orion just posted about.

    I am using my sparetime to find the right lines for our future 50-footer. It is fun but also challenging to keep our signature look and still renew it. This is the latest version...

    Good compromise. Is this one offset? Looks like access from both sides.

    The real challenge will be to start off from scratch and not be tied to any signature for future projects.:)

    WOW! now that's what i'm talking about

    that one is just perfect (except the props, they're looking wrong placed)

    is it possible that you add a upper seete like on the 40 footer?

    maybe that would make the point :)

    Lars,

    You have mentioned earlier that you have some concern for the general acceptance of the design, hence the raked screens at this size (By the way the present look of the wind screen looks good). I believe you and the production team have somewhat an ambition to market the boat in foreign markets, specifically for the warmer climates; Med.

    In this respect, I think you need a larger aft deck/cockpit. You may reconsider the glass extension of the saloon to be a part of the aft deck. Also, in my opinion there should be some kind of awning as a sun shade attachment. I have seen a good example on the Alloy yachts "Como", just like the awnings we use for the buildings.

    Codger, yes she has two sidedecks and will probably have a door each side.

    Jannick, good that you like the design as you proposed! The props is in the right position. About a flybridge, this will not work since we want a glass door to the salon there.

    And Nilo, some boats will end up in the Med. At first I was thinking of the aft door going up like an estate car hatch to provide something like an awning, but some want a sunbed out there. People also want a giant waverunner on the platform (that will destroy the aft deck). My idea with the aft glass was to create a salon that was connected with the aft deck so you just opened and added easy chairs to a clean deck. Perhaps with a retractable awning. Inside there could be an AC curtain.

    The problem in this size is that people expect it to have all the facilities of a much larger yacht and I want to build a light and fast boat...

    Lars, you're right!

    It's very difficult to design a multi-climate 50-footer.
    The option with large sliding doors and a retractable shade-blade (preferably hard, not soft) should be more than acceptable, rather than to "destroy" your initial "trademark" design!

    Thanks TRY, you are right about the multi-climate issue. People often see the boat at an indoor boat show first time and dream about sunny weather and calm seas. Our boats are all with a cruising speed around 40 knots and then you can not always expect to be sunbathing on the aft deck.

    I still don´t know how the final boat will look like, but as soon as I settle on a profile, I´ll start with the interior and details.

    I just receieved this picture from our Norwegian retailer testing out the new D29 prior to be delivered to a client. I am sure they will run the 50-footer even harder...

    Hang on!

    :eek:
    Oh my gosh!
    What a great shot...love it.
    Very good looking and robust boat.
    Hope the guy at the helm can keep up!

    Lars,

    The more I look at these powerboats the more I want one! They seem capable of going out in any weather, true 4x4s of the sea! Let me know if you need someone to test them over here in the US! ;)

    The evolution of the 50-footer continues. Here is a recent rendering where the aft deck will be more liveable. One problem now is that the IPS-850 is bigger than I expected, over 3m (10 feet) long! Also that the new drive will need more space to turn without hitting the inner hull, so I may have to abandon this special hull, or the IPS....

    Perhaps a 50 footer in this style is just not meant to be if the compromises required have too high a cost.

    Maybe, maybe not..? With Arneson drives we will reach the 40 knots cruising speed, but at least here, people have problems running them. They go too fast when you go slow...

    I will meet with Volvo Penta after next week when they are back from the US to find out what can be done. The boat should not be longer than 14,9 m due to driving certificate requirements in certain countries and if it would be longer it should need to have crew accommodations.

    So it is a size with few power options for high speed and low fuel consumption.

    As Solar sails are now getting closer to reality i have added an extra mast to the 46 m NEO classic power-sailer. Still mainly for sailing in sun and open winds, it reminds us of the steam-sailers 100 years ago.

    Almost, but 3,5 m, which is allowing her to slip over most Caribbean reefs. As she is not rigged for tacking, a long keel will make her sail pretty well. In ports the azipods will make her easy to handle.

    Lars,
    I prefer the 50 with the reverse window, just has more cut to it in my opinion.
    All the designs look awesome, I have been lurking through the posts for a while and must say you have an impressive eye for flash but with subdued traits if that is a possible description.
