MASHAALLAH khub valo video....

I am a former commercial fisherman/lobsterman, ( with some rather advanced vessel designs of my own). I just wanted to say that you have a great looking vessel design there, but if you wanted, there are still some further advanced design aspects that you could incorporate in with your design that would really put every other multi-hull vessel design in your dust. Using some design aspects taken from a variety of other SES types of vessels such as ... a wider bold flying wing shape, (to harness the WIG effect), inverted -v bow entry. 4 stabilizing lifting foils (which could also be connected to a ride control system), a CAB - captured air design aspects, (flat bottomed sponsons with small air cavity. This would not be a hovercraft, but would include an active, and passive air induction system, and low volume, stepped air spaces, (providing an air lubrication under the hulls). With some of these advancements incorporated into you original hull shape, i wouldn't be surprised if you actually doubled you current speeds, which would also significantly improve fuel efficiency, and range.

The SWATH SLICE can get up to 130 knots.

Impressive performance.

Very functional, congratulations

very interesting!!!!

It's cool to see innovation that hopefully will rescue the boat builders future in Norway, Almost all of the yards are gone bankrupt, I do think it's only about 5 of the bigger yards left.

very interesting!!

planning a boat build for travel. this is close to what i drew up. except I think id like the, wings/pontoons out to the side a bit for better stability, and round the top of the boat some, so if turned over it will right its self.

my my, I remember MY SPIRIT yacht. i miss that boat. A wave-piercing yacht.

Looks like smooth sailing. The bridge view gives a better feel for how it should perform. Taking in the boat scale relative to the waves. It looks really stable...

WOW

I really liked the side by side comparisons to the conventional monohull. I'm wondering how this kind of hull but with a narrower beam would behave. I'm looking for something suitable for both coastal as well as canal travel, so limit on beam would be 5 or possibly 6 meters. I figure about 15 ton. I didn't see what your draft is, but that would be a concern for me.

With SWATH, water draft is variable. On canals, air draft is another concern, and is as variable as the water draft.

Strictly speaking, it's rather what is called a Semi-SWATH or Swathed- classical catamaran. The SWATH is when tou have fully-submerged torpedoes under sharp fins instead of hulls.

I drove the very first swath boats to be certified by the USCG in United States Navatek-I and Navatek II and Sea Slice. Small Waterplane Area Twin Hull. They definitely need stabilizers you can have all four or just two. On following seas, there little uncontrollable as far as roll rather then pitch. We had active ballast tanks where water was moved due to shifting of weight, passengers that is. Great designs tho, but would definitely change the leading edge of the bow. Thankyou

Why not just sit her in the water like a raft on the pontoons??? no more rolling

NICE

I always wanted a submarine. This is halfway there. Looks like the bottom paint bill is going to be pretty high, unless it’s dry docked often.

It is hard to tell from your model how wide the amas (or torpedo tubes or whatever you call them) are. Is there enough room for a diesel and clearance to work on it, or would that be up high with a shaft or generator to drive electric motors?

❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

SWATH hull's always preform well the two to one ratio make's them hard to find dockage for them in marina's.

Beautiful SWATH design, although - for a boat with a rather low beam/length ratio for a "catamaran", especially one that's sitting rather high in the water - I wonder about vertical COG, righting moment and as a result: capsize safety. Would it be self-righting in a "turtled" state? Also: is there only forward visibility?

Hi Christian, Thanks for your feedback - I like your thinking! The concept has adjustability with reference to COG by adding water to internal ballast tanks. This means, if required, the vessel can be lowered to reduce the effect of COG position in extreme weather conditions. NOTE: All testing conducted has so far excided our expectations significantly. Finally; regarding visibility, it is a prototype and will be adressed :)

@@seatechnology3585 Hey Guys Beautiful design. I was working something out on paper very similar. Reading the above comments and lacking the ability to do quality model testing... i was wondering if you considered placing a series of pylons in the lower hull below the waterline holding a set of pontoons at depth allows for wonderful stability increases the wave clearance in such a way that the ship is stable and facing into a current allows for much easier stable positioning. Working out the details to mechanically or hydraulically to control the depth for special applications so that underway the shape is similar to your above shape. At rest in deep water the ship rises 1/2 the length above the sea level and ignores the wave action. LOL... I am only at 3:35 in the video. I should have watched the whole video but got excited and paused to read the comments.

Hello, this is an interesting vessel. I have a curiosity as a passionate mind, if some of your naval architects would enjoy using their spare time to think about it. If they were to time travel back 100 years, could they implement such a multi hull design to create battleships, battlecruiser or any capital warship. We are talking of vessels of 30-50.000t and over, with armour plates and sailing the oceans. It would be a fun video engaging in such fantasy theories on your social media following. What about an aircraft carrier of those times? Having access to steel works from 1 century ago, without modern carbon fibre, titanium and other fancy materials, but using the knowledge of today they posses in this field. Thank you, and congrats on the modern vessel you made

The struts should be hydraulic, so they can compensate for all the motion. That way the could eliminate seasickness!

It looks like a minivan sitting on pontoons. But I still want one.

nice concept and good performance call it the 'turtle' instead of 'shark'

good sharing. where the location towing tank test? thanks

Imagine combining this with the active suspension from Servo Yachts. Would completely eliminate seasickness.

how much weight can you put on a vessel at 32ft application of this design

If the swath boat is really high off the water like 12-16 ft, it helps a great deal. Also instead of huge solid plate attached to the underwater hulls, it's better to use steel ibeams, perhaps 3 on each side or triangular shaped beams with the pointy side facing forward for hydro dynamic flow. The underwater hulls should be tubular with a very pointy nose, or they could be long narrow knife blade shaped hulls with a sharp nose to cut through the water. The most important aspect to keep the boat stable while at cruising speeds, with a stabilizing wings in between the hulls attached on the inner side of each hull, at the front & rear. Just airfoils that don't produce lift & or a downward force, just neutral balancing stabilizers. With beams instead of a huge wall on each side the water could flow through the open area instead of hitting a wall of steel when the boat is getting hit by side chop or if turned side ways in heavy seas.

Thaks for your feedback and thoughts around the design. Firstly; the vessel is built in a combination of GRP (Glass reinforced plastic) and CRP (carbon fiber reinforced plastic). Steel/aluminium is old fashion and a no no ;) The hulls are slender, but still accessable from deck to the hull. The concept of using beams is known, but not very practical for inspections/repairs or general maintenance. With reference to foils, the vessel will be installed with 4 foils currently in development - with a unik design which we hope to present for a great varaiety of vessels. Sea Techology

baloiça mais do que eu quando estou bêbado, hahahahahahaha

What like about this design. It could also be a submarine. I would have it have the capability of it going down to 66 feet.

I hold my breath every time she goes down. She looks like it couldn't take much of a pounding.

Looks like a lifeboat.

Looks like not SmallWATH, but ReducedWATH, or special conditions optimized hulls Cat with no usefull values in it

So, the target customer base must be squirrels then?

sigh when people like you just dump a whole shit load of money into a flawed design then you will understand the reason it is on a small scale. The cost of the small scale is less, for testing reasons i.e to improve any flaws in the design if they need to. It would be stupid to not test your design before actually building the whole thing, It would be a waste of money as well because no one would want it if it is flawed. even though you the consumer don't get to see the roughs design before they role out the finish product, that doesn't mean rough designs/ prototypes does not exist and they are many despite what the marketing team may display to the market.

Are the top speeds limited since it is not a planing hull?

@seatechnology3585

3 жыл бұрын

Hi, Yes; the top speed will be limited due to shape/type of hull. With reasonble power - without going overboard - the top speed will be at 20-24 knot. Beyond this the power demand is too hefty. This said; at lower speeds the hull is highly efficient. Part of the hull is actually - without being 100% comparable - used on our latest boat MS Ole Bull (kzread.info/dash/bejne/mG13vMWAnszHZJM.html). For this specific vessel the total power consumption is 14 [kW] at 6 knot / 44 [kW] at 8 knot / 110 [kW] at 10 knot. NOTE: The hull is designed to be more efficient at greater hull depth then what is the case for MS Ole Bull.

Center of gravity too high. Beam width too small. Never should have got off the drawing board. The following sea testing is not reality or accurate. The broadside tests much worse.

It’s not slicing through the waves . Should have used higher displacement torpedo hulls and thinner struts
