Seabed undulation can form due to various geological processes, including tectonic activity, sediment deposition, and erosion. Underwater volcanic activity can create mounds and ridges, while the movement of tectonic plates may lead to the formation of faults and trenches. Additionally, the action of currents and tides can shape the seabed over time, creating features like sandbars and underwater dunes. Human activities, such as dredging and construction, can also contribute to changes in seabed topography.

What are Admirality pattern stockless and CQR?

The Admiralty pattern stockless anchor is designed for effective holding power and ease of stowage, featuring a fluke design that allows it to dig into the seabed quickly. The CQR (or "plow") anchor, known for its plow-shaped design, is also effective in various seabed conditions and is renowned for its ability to reset itself if the vessel drags. Both anchors are popular choices for recreational and commercial vessels due to their reliability and performance in holding.


What is the minimum recommended length of anchor line for an over night stay?

The minimum recommended length of anchor line for an overnight stay is typically 5 to 7 times the depth of the water where the anchor is deployed. This ratio accounts for both the vertical distance to the seabed and the horizontal drag from tides and currents. Additionally, considering factors like the type of seabed and weather conditions may affect the required length for secure anchoring. Always ensure that the anchor is securely set to prevent dragging.


A ship drops its anchor The anchor traveled 217 feet to the sea floor If the anchor started at 20 feet above sea level what is the present elevation of the anchor relative to sea level?

217 - 20 = 197 Therefore, it is 197 feet between the seabed (and anchor) and the sea level.


Would half and half be rotten if it was frozen but expired 2 years ago?

Thaw it and smell it. Freezing usually stops the microbial action that "spoils" food. A few years ago a Roman galley was raised from the Mediterranean seabed and butter was found in barrels on the ship. The butter was still edible.
