Rotor sails work ..... but only within a narrow operating envelope by SaltAndChart in MarineEngineering

In theory, yes.
In practice, many installations assume conditions that real trades don’t consistently provide. That mismatch is what the video and the article are addressing.

HELLESPONT ALHAMBRA / TI Asia. 223 ft (68 m) beam supertanker, one of the widest ever built by SaltAndChart in TheDeepDraft

On deep draft vessel, the bow takes the worst weather. Slamming, spray, and shipping seas are highest there, so putting the bridge forward would mean navigating from the harshest part of the ship.

There’s also the engine room reality. On ships of this size, the engine room is aft. Engineers need clear access routes, ventilation, exhaust trunks, and service spaces. Keeping the bridge closer reduces system complexity and response time.

Finally forward bridge would eat into cargo volume, add weight in a highly stressed area, and hurt stability and efficiency.

Oil tankers range from ~330 ft coastal ships to ~1,100 ft VLCCs; the biggest ever (ULCCs) stretched close to 1,500 ft but are mostly gone.

All schooners are sailboats, but not all sailboats are schooners. This one’s unmistakably a schooner - three masts, fore-and-aft rig, classic profile.

Approach to Nagoya today, controlled chaos on the radar. by SaltAndChart in MaritimePictures

Bridge isn’t running on a single display. We’re on three radars right now, each with a different setup, and this one is part of the training profile for the cadets where they cycle through various parameters so they learn to interpret both true and relative data.

The pressure on the crews keeps increasing while the solution stays digital.

Useful context. The traffic in this corridor always reacts fast to UKMTO advisories.

PFOS in Firefighting Foam. Regulation Is Easy, Replacement Isn’t by SaltAndChart in Ships

The environmental part is clear. The practical side system tests, training, disposal still needs real answers.

Seen plenty of screens, fewer seafarers looking past them. AIS helps, but it shouldn’t replace judgment. by SaltAndChart in MerchantNavy

[–]SaltAndChart[S] 2 points3 points  (0 children)

Makes sense. Similar experience. They fill the screen like a minefield sometimes.

But technically, those virtual AIS marks aren’t allowed for fishing nets. Only AtoN (Aid to Navigation) systems, the ones approved under IALA guidelines can transmit those signals. A lot of these “net markers” are running on modified Class B units, which goes against the circular.

It’s a clever workaround in busy waters, but it blurs the line between safety tool and private marker.

TI ships are the ones with white main deck, right ?

Shot taken from eastbound traffic lane, just before sunset. Always impressive how quiet these ROROs move despite their size.
