Great Picture! Its normal to dip the bows in low frequency swell - wish we had our cameras with us when we saw commercial shipping plowing through a force 9 near the Fastnet - even more spectacular!

Great pics but surely none of these pics are of really rough weather (just look at the crew and guests on the decks of some boats) and, in any case, if I had spent zillions on a superyacht, I'd be pretty upset if it could'nt handle a bit of a sea
I have to agree - the weather is not that rough - seems like the bow section does not have enough buoyancy - I suspect style before function in the desigbn of the boat.
I had the same feeling, maybe the boatts are just too heavy and don't have the flaired bow that most smaller boats have which gives them more buoyancy. Look at any of the Aquastar/Nordhaven/Fleming and they all have that raised bow for conquering big seas.
Yes ... I kbnow little about super yachts but as they approach the perfect wedding cake look it seems they might be sacrificing sea worthiness for sexy looks.
Whilst a simplitic way of measuring sea worthiness the height of the bow is something I look at more and more.
My tarder 575 was alongside my froends old Trader 41 and the height of the bow was about the same - seems that they just extend the hull on some boats.
My new Marlow has bow almost twice as high as does the Fleming etc.
I would be dissapointed if my boat dug into waves like that super yacht.
Surely these spectacular bow diving shots are a result of the lenght of the yacht being in harmony with the length of the swell? In that case I doubt that any amount of bow flare would save them?
I bet you won't be disappointed, but for different reasons.
Besides what KCook correctly says, your new boat, albeit heavy(ish), is extremely light when compared to those ships.
That's another reason behind the different behaviour - though of course the hull shape does also affect it.
Just look at the following pics: this tug has a fairly high bow, but it still dugs into waves similarly to the previous superyachts.
Why? Simply said, because when some 3k Tons are going in any direction, it takes time to move them anywhere else, even for a huge wave.
PS: imho, some of the superyacht piccies have a sort of photoshop feeling, either...
Oh, I agree VERY much that more attention should be given to the balance of these yachts. Packing the bow full of fat staterooms (on two levels yet!) is not going to help sea keeping. But in monster swell there is only so much you can do. Short of lengthening or shrinking the hull 20 feet or so ...

PS - Great shots of the tug MapisM ! /forums/images/graemlins/shocked.gif
Correct Mapism. A heavy boat in displacement mode is indeed going to look like it's digging it's bows into even quite a moderate swell and so give the appearance of lack of buoyancy but in actual fact, the bow will always rise again

[/ QUOTE ]Yup, impressive, aren't they?
The machine is even more impressive than the pic: she can still cruise at 16.5kts (just 3kts below normal cruise!), fully loaded, against a F7 head sea.
I'd pay something just to sit on the command bridge and see the bow smashing waves at such speed...
...ok, unless they'd ask me to pay the fuel bill, considering the 20+ thousands HPs! /forums/images/graemlins/grin.gif
