Vessel Yet another Egyptian sinking - the Triton

[Scared Silly]

I am not a marine engineer, but previously a Mech Engr. so lots of questions with few answers.

While water is used as ballast, I don't think it would be appropriate for a motor yacht because the need is more permanent, such as lead which 11 times more dense. Looking at the hull of the Triton which appears to be quite shallow, I would likely say there was not enough ballast.

As for the building of the ship. The quality is probably quite descent. That is, the boat was built as designed. The issue is the design. For instance, lots of wood was used for the interior walls. Wood studs are ~3x heavier than steel. That adds lots of weight above the water line.

At this point who did the design and who reviewed / approved the design?

Ship ballast is dense material, usually water, placed low in a ship to increase stability and counteract the weight above the waterline. Ballast tanks are compartments that hold water and are used to adjust a ship's buoyancy, trim, and draft. Here's why ballast is important:

Actually rarely water, more typically iron or sometimes lead.

Actually rarely water, more typically iron or sometimes lead.

Water is, not only heavy, but also liquid that can be pumped to the opposite side of the boat swing. If the boat is swinging to the port side, the water can be pumped to the starboard side to dampen the rocking motion more effectively than a solid ballast.

Another technology to dampen the rocking motion is gyro stabilizer as shown in the video, below:

Heavy furnitures are usually bolted to the floor and would act as dampeners. Otherwise, the side-to-side rolling would get worse by having the furnitures sliding across the floors.

Except none of those features were used in that *wooden* Egyptian liveaboard. The last thing you want in a wooden hulled boat like that is masses of water sloshing around (a free surface effect) especially in spaces that you can't protect from wood borers.

That’s what liner, coating, paint are for. However the videos above show other active ballast like gyro stabilizer and fin stabilizer.

What was the disposition of the Triton after it capsized, did it sink or was it salvaged?
