The concept of an adjustable bow bulb actually has a bit of history in and of itself. Robert S. Boston filed a United States patent in 1967 on behalf of himself and David J. Seymour. Patent US3540400A was approved in 1970 and describes an adjustable bulb through the use of hydraulic power. Whether this was ever fitted to a ship for testing is something I'm still trying to research.

He almost has the mid Atlantic "announcer" accent that we grew up hearing everywhere. (Not quite like Cary Grant but along that line) Or maybe it's just because he wears a shirt and tie, looks and acts like the professional he is. We don't see many people like that these days so when we do it seems like something we should be able to associate with a memory. I dunno, I'm just guessing. :)

Any boat. With no bulbous bow they surf the bow wave. They do it with sailboats all the time and those have classic hull forms.

An added benefit of your ship wearing a strap on is that it also increases buoyancy of the bow. If you ever watch an Iowa class BB in heavy weather crashing through the waves, they don't have a lot of reserve buoyancy in the bow with their very small bulbous bow. A far larger bulb would add more buoyancy back.

When one is on a ship I think it would be a bit rude to ask to see the bulbous bow so thank you Mike for shedding some light on it for us. I always wondered why they were there!

There is a caveat or two for them: 1) a bow design works for 1 hull size + shape at 1 speed. 2) on a smaller boat, like a motor yacht under 100 feet in length, they actually work as a stabilizer and slow down the pitching of the yacht. ( the fin stabilizers slow down the rolling not the pitching )

Well done. Nice Rupert Holmes reference at the end 🥂

Looks like a giant codpiece... Thanks for this video as it answered a question of mine I have wondered about for years.

Being able to retract the bulbous bow was a great idea! With airplanes, you use flaps to increase the surface of the wings to produce more lift. It allows you to fly at a lower speed but it also produces more drag, so the pilots can just retract the flaps when they don't need them anymore. Every large, fast ship should have retractable bulbous bows!

Always happy with my friend Mike Brady from Oceanliner Designs uploads a new video.

Thank you Mr. Brady for your great work and dedication.

What is a bulbous bow? Bloody clever, that's what! They do look like a ship-sized cod-piece, but you can't deny their efficacy. Some version of the tubercles on whale fins, which allow for more 'lift' but with less drag, will find their way onto rudders and stabilisers I think.

Fascinating. I always imagined it was to deal with submerged objects. This makes much more sense.

This video answers a question I didn't even know I had! Thanks

Thank you for explaining so succinctly! Destructive interference, how cool!

Good explanation. The inverted bow at 8.13 (celebrity edge) won't take more waves over the bow. Quite the reverse. The shape greatly reduces pitching and remains drier. Traditional ships with their wide flared bows generate a lot of lift from approaching waves and this lift initiates the unwanted pitch-drop-pitch-slam cycle. Remove the lift and you get less slamming. Efficiency still matters so many of these newer axe/x/knife/inverted bow designs still include a bulbous shape below the water line. As such I imagine this one does also.

I know no one would ever build one but I would enjoy seeing a naval architect and a weapons expert redesign an Iowa class battleship using modern hull technology and powerplants. The hull would have to be capable of transiting the Panama Canal. The ship would be used for shore bombardment, refueling and rearming helicopters and VTOL aircraft used for close air support. Keeping the forward 16in. turrets and 5in. turrets would provide for shore bombardment, removing the aft 16in. turret would allow the aircraft facilities to be installed. A ship capable of these tasks would help alot of US Marines sleep better at night. And before you ask I'm an USAF veteran.

This is very much like "tuned exhaust" pipes on racing cars. The exhaust gasses travel in pulses created when the exhaust valve opens, and when each pulse reaches the air at the end of the pipe, it over-expands, which creates a low pressure zone around the end. This means a negative pressure pulse travels back up the pipe to the engine. If you time it just right, the negative pulse reaches the exhaust valve just as it's releasing a new pulse of gas. This helps "scavenge the cylinder" to a greater extent, which, in turn, leaves more room in the cylinder for the new fuel/air charge. As you can probably guess, this only happens at a very narrow range of engine speed, so the pipes are "tuned" to be most effective at the power-peak of the engine, just like the bulbous bow.

Oh jeeze, the closing joke made me groan! 😃

Years back I worked at a shipyard in Boston. We fabricated and installed bulbus bows for the Knox class frigates. We called them sonar domes. They were clad with a B. F. Goodrich rubber "boot" almost 2" thick. No steel, which allowed the sonar waves to propogate. The compartment behind the rubber was flooded to allow sound transmission and had to be pressurized. I hate to think of what happens to any marine life near these vessels. The sonar equipment was not to be energized while in port in case any divers nearby in other yards were working.

Unfortunately active sonar use (especially modern sonars) are known to cause huge impact to wildlife, such as causing entire pods of whales to beach.

The first Nimitz Class aircraft carrier with a bulbous bow was CVN 76, the USS Ronald Reagan. That was also the first Nimitz Class carrier to have its island moved slightly aft. The Bush went a bit further aft with CVN 77 and then the Ford Class moved it rearward again.
