The difference between Gross Tonnage and Net Tonnage

This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...

It is not often that this blog is used to show bad practice, however in this case some pictures tell a whole story. Ship is compliant by design for rigging a combination. How about the operator(s)?

New guidance for PBAs with trapdoors. Released 4.11.2020 at NZMPA Conference in Dunedin, NZ. Distinct difference to suggestions in many other countries, is that we challenge operators who have the ladder suspended from the accommodation ladder (gangway) and not secured to the ship. SOLAS states that pilot ladder shall be secured to the ship, and securing strongpoints, shackles and ropes shall be as strong as the sideropes.

Maritime pilots work in an irregular deployment system (rotation system) with unpredictable work assignments under high levels of physical and mental stress. Fatigue or chronic diseases, e.g. coronary heart disease, peptic ulcers or gastritis can occur as a consequence.

Recently, Svitzer took an important step towards strengthening its presence in Africa by signing a five-year contract with Nacala Logistics in Mozambique for harbour towage, occasional pilot transfer and potential salvage work in the port of Nacala. At the same time, Svitzer also secured a five-year extension of its current contract with Egyptian LNG assisting the land-based Idku LNG plant with four tugs, two mooring boats and one pilot boat.

Australasian Marine Pilots Institute or AMPI held its first ever regional conference outside of Australia in Port Moresby.
The conference opened on Monday night and it continued today and tomorrow with discussions on regulation, pilotage in PNG, training, towage, transfers and technology.

Vos Pace is a Dutch registered ship being seen out by Puffin Pilot vessel at Great Yarmouth 8th June 2021. Vos Pace is 83m long and 18m wide and made in 2015. Puffin is as long as Vos Pace is wide at 18m and 4m wide itself
I run over and managed to grab some nove shots even though the sun was facing into camera some of the time. As Puffin came back it looked even better I thought.
Music by me.
