Ship owners don't spend the money on pretty finishes, those are for yachts.

I notice the not so smooth hull finish too which made me scratched my head a little.

@@100PercentOS2 I think that the aluminium means it is hard to get a smooth finish over a large area because the thickness of the plates is reduced to reduce cost and weight. But I have even seen that sort of uneven finish to a lesser degree on some steel hull frigates.

This is a commercial trimaran. I'm willing to bet they used materials & a design that can stand up to day in & day out abuse. But they may be some drawbacks with the type of finish you ends up with. But the draw backs are mainly cosmetic.

It is really disappointing to see that hull finish.

Or a Littoral Combat Ship

Yes and I think the red colour makes it look really nice.

The RED color makes it go faster.

oh yes please

Second this. The quad jets looked awesome!

A band called Queen ? Yes A band called The Beetles? No Sorry only 1/2 correct.

Austal specialize in Trimaran hulls

Actually they not that exact, though they're trimaran craft. The one you're talking about is the Benchijigua Express operating for Fred Olsen Express, not Norwegian. That vessel can carry passengers and vehicles. This vessel, the Queen Beetle can only carry passengers.

Hermosa. Te saludo Cordialmente desde CHILE LATINOAMERICA.

Its not a yacht its a ferry

It's more of an outrigger than a hydrofoil

@@kellytozarindamasceno6709 wow I thought ships worldwide were referred to as she. Maybe it's just an English language term. I'm from Belfast.

@@MONK-7 No its not just English the french, germans and many others do it too perhaps its a European/western thing

Josuke22 Yes Josuke. I have been involved with a number of these jet propelled vessels in my time working in the marine industry. From what I see, so much of the power is lost in froth and bubble. I would take conventional propeller thrust as opposed to jet propulsion anytime.

The ship is not really that large, more about mid size. Don't know about it using 4 waterjets though when it could just use only three like on the HSC Benchijigua Express. Catamarans and trimarans can take advantage of high speed by powerful propulsion like waterjets because they have higher efficiency and create less drag when cutting the water compare to monohull vessels and allow the waterjets to operate efficiently. Only worry about if they use waterjets on monohull vessels because the size of the hull and how it creates more drag will make waterjets inefficient in providing propulsion for these type of vessels. So waterjets can operate at higher efficiency than propellers, that's why.

@@robertmayhew98 propellers can produce bubbles as well through a phenomenon call cavitation. If you have been seeing lab experiments of propeller moving through a liquid, you would clearly see bubbles forming on the outer edge of the blades. Both impellers in water jets and propellers can suffer from cavitation, the only difference is that the damage maybe limited or doesn't occur often in a waterjet than with a propeller.

Hi Trinispace, Thank you for your article re marine propulsion. I understand and totally agree with you. Propeller cavitation. I have always been fascinated with the action of propellers in water. Something to do with the amount of oxygen in sea water? Yes when it comes to trimarans, catamarans and other high speed hulls the jet propulsion is certainly far more efficient as compared to conventional propeller drive. Minimal water displacement with such above mentioned type hulls. I was probably more concerned with manoeuvrability in confined spaces and when docking. On many occasions I was required to be on standby to assist with the docking of one of Austal’s newly built vessels. The water all around the vessel was so aerated ( my bubble and froth) . Of course a lot of power is needed at times given the windage effect on many of Austal’s high sided vessels. I feel that the conventional props would be to advantage in these circumstances. Perhaps some of the newer type high speed vessels have the added advantage of bow and stern thrusters?

@@robertmayhew98 Maneuverability does be an issue with waterjets only at low speed or low engine rpm. That is because of the surface area of waterjet (well the impeller actually) is generally smaller than a standard propeller. A propeller could displaced great amount liquid because of its large size but still require greater thrust and the rudder for maneuverability. Waterjets require thrust, maybe at 20% or 30% of engine rpm to maneuver a vessel, but at high speed they can turn a vessel faster and sharper than those with propeller. That is because waterjets can generate greater thrust even at same engine rpm as though with propellers. I'm living in Trinidad & Tobago, two islands located in the Caribbean just off the coast of South America, Venezuela to be exact. When i commute between both islands so often, i used the high speed catamaran ferries powered by waterjets, many years before we use to have monohull vessels driven by propeller so i have some knowledge of marine propulsion. We are in a process of taking two new fast ferries, one is already built and is fitting out. Austal built this one named A.P.T. James, a 94m high speed catamaran ferry for us. Incat is building the other one for us, a 100m wave piercing catamaran which suppose to be completed not too soon. That one would be named Buccoo Reef.

dont think Santa has a shipyard

Stability and a lighter keel thereby faster and more efficient

@@tumao_kaliwat_napulo Thanks for your comment. Since I'm Japanese, I'm lokking forward to use this ship. And thanks for Austlaian made this great ship!
