How about this for a bow then??

X-BOW® design - Ulstein

To preempt RT fly, "what hump?"

That's still too deep for most of the ICW.

9 feet draft is a bit deep for a 55, but a open ocean work boat probably makes it much more stable.

Hi, Stubones99-
I'd call that one a parrot bow, from the front it looks just like one.
The ships look pretty good, but wouldn't water (in bad weather and rough seas) splash right up that ramp and blast the pilothouse?
I bet they're fast.

These have been popular for offshore work for some time. I have to assume they get the job done. But talk about UGLY!!!

I guess if you make a living designing boats (just like buildings, for that matter) churning out traditional designs is not the way to make a name for yourself.

Sort of like the art world; if it's not new, different and shocking, it doesn't make a buzz.

Maybe when I'm long gone, this WILL be the traditional design. After all, it has proven itself for about 10 years so far. But I still see it as a solution in search of a problem at best, or a fashion statement at worst.

Time will tell.

Seems to me we really have no real information to draw any accurate conclusions on the merits of different bow shapes for our boats. Ours came with a bulb, but I doubt Selene would have been able to provide hard facts to convince me to spec it out that way.

PS - don't blame me for lack of maintenance The pic was taken during pre-purchase survey few years ago.

No Mast,
What's that thing hang'in down under the bulb?
A fwd shooting sonar?

It would seem to me that if you .. no when you slam into big seas that thing will be subject to very high forces and must be quite heavy and strong to not get damaged. But assuming it does lower drag at some speed ... and you do go that speed the extra weight and cost may be worth it. Adding weight to a boat isn't often a win win.

Tom,
New, different and shocking applies to the political world as well. Not to mention the media. Both have run wild because of it.

My guess is many bulbous bow might actually add buoyancy or are neutral.

Yes, i know it's something behind the boat, but it's funny!

Those are called wave piercing hulls but it looks strange! Imagine how hard it must steer. Assuming it is two hulls, there are two engines (just an assumption) which would make it easier to navigate in close quarters.

Bulbous Bow

As has been stated, they have to be designed and applied correctly. There are many boats performing fine with and without them. Here is a picture of ours and Ed Monk's design philosophy in applying it to our boat.


"Hull is bulbed, which effectively increases waterline length for slightly better efficiency and speed. Bulb also damps pitching, but is elliptical in section to minimize splash when entering or leaving the water. The hull was disigned with the bulb not added after the fact"


Having spent a lot of hours on similar displacement hulls without one, I can say the bulb is a positive addition to our hull's design.

Why can't I get a picture to embed? Would someone be so kind as to tell me what I'm doing wrong. I follow the steps below to add it, but it doesn't come through.
