From the Marine Guru: Understanding Ship Squat & Shallow Water Effects 🌊

Ever wondered why a massive ship appears to sink slightly in shallow waters? It's a critical phenomenon called Ship Squat! It's a major factor in navigation that can cause a ship to ground even when it seems to have plenty of clearance. 🚢

What is Ship Squat?
When a ship moves forward, it pushes water aside. This water has to rush back underneath the hull to fill the space behind it. This fast-moving flow of water creates a drop in pressure, causing the ship to sink lower into the water.

It's a Vertical Drop: The ship effectively experiences a vertical sinkage.

It's Not a Change in Draft: This isn't a simple increase in a ship's draft reading—it’s the overall decrease in the under-keel clearance (the space between the ship's bottom and the seabed). ⬇️

Bow or Stern? Where Do We Ground?
The way a ship "squats" also depends on its shape, causing it to trim either by the bow or the stern. This can determine where grounding is most likely to occur.

Full-Form Vessels: tankers and bulk carriers, which are wide and blunt, tend to ground at the bow. ➡️

Fine-Form Vessels: Passenger ships and container ships, which are more streamlined, tend to ground at the stern. ⬅️

The Science Behind It
Bernoulli's Theorem: This is the principle at play! It states that as the water's speed increases under the hull (higher kinetic energy), its pressure decreases. Since the ship is supported by this pressure, the drop in pressure causes the ship to sink. 📉

Understanding Ship Squat is essential for every mariner to ensure safe passage in confined and shallow waters. Stay vigilant! ✅

What a nice cruise vessel!

SAJ Instrument at World Maritime Forum this week in Copenhagen promoting the No. 1 Dynamic Measuring system SAJ-DMS and energy saving module.

We congratulate Gotlandsbolaget on the new vessels, Nordic Crown and Nordic Pearl, which DFDS has recently equipped with the proven SAJ-DMS system, known for its accuracy and reliability. www.saj.ax

Kim Heiberg, route director of the Copenhagen-Oslo route for Gotlandsbolaget, has confirmed to Shippax that the new names for PEARL SEAWAYS and CROWN SEAWAYS will become NORDIC PEARL and NORDIC CROWN.

PEARL SEAWAYS is currently at the Oresund Drydocks in Landskrona as the first of the two ships to receive refurbishments on public areas and upgrades to all its cabins. It is expected to leave the yard at the end of the month as NORDIC PEARL. Work on CROWN SEAWAYS will take place in March and will leave at the end of that month as NORDIC CROWN.

The 2025 Shippax Ferry Conference will take place onboard the NORDIC PEARL between 2-4 April https://www.shippaxferryconference.com/
