Is it s trimaran set up? (multi-hull setup), and it looks like its in navy colours.

I think that might be the Vosper Thornycroft Triton

Yep, That's the Triton

Yours for €2.5m if you're interested type

Go in with your size 10s on and offer them €2m and negotiate a tank of fuel in the deal

Yours for £2.1m if you search the web for the name. wink

Aha! Beaten to it smile

Article seems a bit out of date. The Independence class LCS boats are larger. Is that recent? Is it for sale just now? Or is that an old page?

Also, for the life of me, I cannot see it on google maps? I've tried that link a dozen times in case it was taking me to the wrong place?!

Its in the Hull dockyards (just to the west of the Ferry terminal) if the link isn't working.

So I read that it was a reasearch ship for the Navy to look at being a Frigate class of boat.

A frigate being something that is a relatively fast, maneuverable, support ship that also has the ability to deploy weapons such as missile defence and anti-submarine operations? (I often struggle to work out military ship classifications, so my description probably needs correction)

So the 3-hull design is likely looking for stability on the waters, although it will likely have less speed and range than mono-hull due to having to drag three hulls through water.

Bizarre, I still cannot see it.

VT built it as a sort of technology demonstrator for FCS (Future Combat Ship), which went on to become GCS (Global Combat Ship), AKA Type 26 Frigate.

I work in shipbuilding/design, but I'm fairly strictly structural, with a bit of mechanical, I'm not a naval architect, but basically, trimaran designs can offer better seakeeping and stability than a monohull, but have a greater wetted area as you say, so more drag.

You also loose a lot of buoyant volume/tankage, as the lower 1500-2000mm of most ships are tanks, so lack of tankage and extra drag affects range.

Also, the centre hull which is usually the only one that extends all the way forward is likely to be more slender than that of a monohull, which can lead to bow trim problems; just about every naval design I've worked on has ended up with a variant of the same problem.

They make them thin and pointy at the front so they cut through the water. But the structure also tends to be heavier here, as bow slamming is a consideration, you've probably seen videos of naval ships bashing through waves that look like they'd snap most boats in half. Then you carry a load of chain in your chain locker, for anchoring.

Then, you smack a large gun, complete with autoload system, large storage magazine and all that associated weight at the front

Not sure what's happening with your google maps but its 1km west of the docked Hull-Rotterdam ferry and its in the 2nd wet dock from the left.

Very strange looking boat from above.


Also notice how many bleeding wind turbines are scattered around, big business for those invested in climate change! wink

2d flat google maps shows it, but 3d google maps (taken at a different time) just shows empty docks.

Ah, yeah that's it. If I go find that location on my phone, I can see it. Cheers. Thought I was going daft or something.

Is the VT vessel similar to the American Independence class LCS? I watched a YouTube vid about how they’re suffering from serious structural issues associated with being made from aluminium and utilising a trimaran design. Not sure how on the money the guy in the video was.

This thing is like an MX-5 compared to the Ferrari Indepdence class. They are ~30m longer, go more than twice as fast, much better armed.

And yes, they had issues with welds cracking, mostly as a result of operating at higher speeds and in bigger seas; the hydrostatic and hydrodynamic pressures acting on the hull, particularly in high stress (in way of openings, sharp corners, house ends and the like) causes the welds to fail prematurely.

They've retired a few of them early, they also had galvanic corrosion issues with the aluminium structure and steel pump jets, and resolving the issues was deemed too expensive.
