They are the same thing, muriatic acid is generally less concentrated than hydrochloric acid. Home pools get muriatic acid, ships get hydrochloric acid, as they are trained in hazmat procedures, and the more concentrated acid requires less volume in storage.

Very few, if any, ships use bromine, as using chlorine allows the same chemical to be used in pool, potable water, and sanitizing solutions. Typically, pool/hot tub chemicals are chlorine and hydrochloric acid.

A certain percentage must be US built, I'm not sure of the exact number, which is why things like the engines and the like can be from overseas. If it fit the percentage, then they could import cabins, but most of those in Europe are built far from the shipyard and trucked/railed to the yard for installation, they are assembled at the manufacturer plant. Not sure how cost effective shipping completed cabins (essentially empty boxes) from overseas would be. My last ship was a Jones Act tanker, which means, like the PVSA, that it must have a certain amount of US built in it. Basically, the hull steel was US made (though the bulbous bow and stern tube casting came from Korea (we just don't have that capability here), everything else came from Korea. The engine, the switchboard (assembled), most machinery flats (all assembled), the catwalks and ladders on the well deck were all pre-fab. It was more like building a model ship.

Given that there has not been a cruise ship built in the US since long before pre-fab cabins were invented, and that for cargo ships, the cabins are built on site (only the bathrooms come pre-fab), and that the US does not have the manufacturers of the pre-fab cabins like Europe, it would not surprise me.

Nothing to do with the age of the ship, it has to do with whether there was a ground fault of some other circuit anywhere on the ship at the time.

Drinking water test kits are in daily use for pH and chlorine content, as these two things are dosed to the drinking water continually (I should have mentioned that acid is added to the water since chlorine works best as a sanitizing agent when the pH is within a narrow range). Monthly, the potable water tank in use, and 6 locations around the ship (chosen at random), are tested for fecal coliform bacteria. This requires the sample to be incubated for 18-24 hours, so is normally done in the medical center. Salt content is only measured at the device making the water, where a salinometer will dump the water produced back to the sea if the total hardness gets too high (typically the alarms are set at 10ppm for evaporators, and 20ppm for RO units. More commonly, you will see a portable test kit for pool water.

See above post. There is nothing other than a small amount of calcium carbonate added to the water.

Most ships have both evaporators (that produce distilled water) and reverse osmosis units. Typically, the evaporators are larger and produce the majority of the water, as they use the "free" waste heat from the diesel engine cooling water to heat the sea water, while the RO units use a lot of electricity (the sea water has to be pressurized to about 1000psi to remove the salt.). There are only two things that are added to water made in an evaporator on a ship (distilled water is slightly acidic). Those are: chlorine for sanitation, and calcium carbonate (the active ingredient in Tums antacid tablets). The calcium carbonate is added only to neutralize the the acidity of the distilled water. It is the acidity that "strips" minerals into the water, as it tries to neutralize itself. There is nothing added for the purpose of changing the taste of the water. Most bottled water actually adds a trace of salt back into the water (along with some sketchy chemicals used in fertilizers and such) for taste, but ships do not.

Your shower head will not be as clean as the ship's one, which is taken off and sanitized in chlorine every 6 months. Typically, pressure problems in a shower are not due to the head, so your head won't make any difference. There is a filter in the mixing valve that can plug up with scale, most Typically in the cold side, and then the pressure balance in the mixing valve will close off the hot water as well, to prevent scalding.

East End Beach is about a mile (15-20 min) walk from the cruise terminal. It is not a real "beachy" beach (more shingle than sand), and has become a bit of a pet toilet. However, taking the Eastern Promenade Trail, which is about 2 miles long, and includes the walk to East End Beach, is very nice for views of Casco Bay and the islands. Some very nice large, old houses along the Eastern Prom. Shipyard Brewery is before the trail, and the Maine Narrow Gauge Railroad is near the start. Of course, going the other way from the terminal lands you directly in the Old Port, and downtown Portland, with all it has to offer.

What not to put down the toilet.

Just know that I've heard reports that ceramic type straighteners will sometimes not work on ships.

Uh, no. Cruise ships operate under maritime law, and the jurisdiction for possession of marijuana products is the flag state, not the US. The jurisdiction in the terminal is federal, but once onboard, you are under flag state law for this kind of thing.

From the lobster fishing zone map, the vast majority of zones are 2-3 months, and only 3 zones last 6 months like yours (obviously off NS or Bay of Fundy. And, according to the Lobster Council of Canada, there are some zones with a maximum size, and I was under the impression that Canada had joined the Atlantic States Fisheries Council in 2007 in setting maximum size limits.

The beneficial ingredient in Cannabis oil is THC, which is the illegal drug in marijuana. And, Cannabis oil has a higher concentration of THC than CBD oil. Can she bring it, and not have any problems? Probably. Can it be detected? Sure, drug dogs are trained to detect THC. Could it be confiscated? Sure. Would there be any other concerns? Only if detected in a place like the Bahamas, where they routinely fine tourists heavily for pot products. Does the doctor's prescription make a difference? No. None of the crew are allowed to have a prescription for this, as stated, the ship is a drug free zone, and the ships have a zero tolerance policy.

That was my senior moment for the day, that is what I was trying to type.

There is also a limit on numbers of traps, and the season gets varied in length by the observed catch.

That depends on whether it is a soft shell or hard shell. Soft shell is a new, bigger shell on a lobster, so lots of room to grow (and it's full of water), but hard shell is nearly time to molt.

Well, picked lobster meat is $65/lb. You're paying for someone to cook it, shell it, clean it, and chop it. While I can crack a bug in about 5 minutes (soft shell), you're again getting less than half a pound of meat.

Historically, it was the opposite, since Canada had no maximum size limit until about 15 years ago, but Maine was the only state on the East Coast with a maximum size limit. It is estimated that a 3 lb lobster produces 14 times the eggs that a 1.5 lb lobster does. So, the maximum limit helps sustainability. Also, Canadian season is only two months long.

The water in the Gulf of Maine is slightly cooler than Canadian waters, leading to softer and sweeter meat.

But, if you've only had a lobster on a ship, you haven't really had a Maine lobster. And, there is no guarantee it is actually a Maine lobster, it could be the inferior Canadian version.

They are frozen, so IMHO not worth the charge. Especially for $27. You do realize that a 1.5 lb lobster only produces about 5-6 oz of meat? The weight includes the shell, and the carapace, which has virtually no meat. Here in Maine, the minimum size is by length of carapace, but generally you can't get anything smaller than 1 lb, what we call "chix". But, as I say, since they are frozen and then steamed, the consistency is changed, and I don't like them. And, I can get a 1.5 lb lobster for $11 and steam it myself.

Interesting that there were problems, as the generators are set up to parallel themselves, automatically adjusting speed of the prime mover to put the frequency of online and incoming generators the same, and the sine waves in synchronicity. Only then will the breaker close, and the power is uninterrupted, and then the unwanted generator is taken off line. This happens every day, sometimes several times a day on every cruise ship. And, hotel power is not separated from other power, it all comes from a common bus that all the generators, whether gas turbine or diesel, feed in common. They should have been able to set the new generator up to match the gas turbine, but not close the breaker, to see that the synchronizing worked, before actually closing the breaker. There may have been problems with load sharing, as the two generators are different sizes, so load sharing is unequal, but proportional, but this is common among strictly diesel ships, as they will often have two different sized diesel generators, so should not have been a problem.

Frankly, I would not use anything that combines USB ports with power outlets. A strictly USB hub (up to 6 or 8 ports) will not be confiscated, whether it has a cord or not, since it is not a "power" extension cord (low wattage). If you need more power outlets, then a hard rubber "multi-outlet" (one male plug and 3 female outlets, no cord) should fit with a outlet adapter if the outlet is recessed. But, frankly, if you plug the USB hub into the 220v outlet, you will still have one or two 110v outlets for power use, without any multi-outlet, and a hair dryer should definitely not be plugged into one of these with anything else.
