This video provides a step-by-step guide for determining the Gyro Error and the deviation by the Sun's amplitude using the Amplitude Table.
Amplitude refers to the angular distance of a celestial body (such as the Sun or Moon) measured along the horizon—from the East point when the body is rising, or from the West point when it is setting.

This video shows a detailed explanation of the Tidal Stream, Set & Drift. It covers how to determine "Set & Drift" using the Admiralty Tidal Tables and then apply it to determine the Course to Steer.

Tidal stream or Tidal current is the horizontal movement of water caused by the rise and fall of the tide.

Set is the direction in degrees toward which the tidal stream or current is moving.

Drift or Rate refers to the speed of the tidal stream or current, typically measured in knots.

This video shows you how to determine the Gyro Error by astronomical observation using the celestial body sun. It demonstrates how to use the Nautical Almanac and Norie's Nautical Tables to find the true bearing of the sun.

A ship's gyro error refers to the deviation or discrepancy between the true north direction and the direction indicated by a gyrocompass aboard the ship. Gyrocompasses are used for navigation and provide a stable and reliable reference for determining the ship's heading. However, like any navigational instrument, gyrocompasses are subject to errors, including gyro errors.

Begin your South Pacific cruising in New Zealand and up into the Pacific Islands aboard this beautiful Outremer 51 available to sail away now.

After sailing from BVI, we arrive in Saba, a dormant volcano rising out of the Caribbean Sea a whopping 2910 feet. We discover that a tropical depression is heading our way so try to cram in as much as possible before we need to run... checking out the two main towns then starting a seriously STEEP ascent from sea level to the peak of Mount Scenery.
The 'cruisey' boat life may finally be catching up with us as we realise how unfit we are only minutes in to the hike!!

Hello Friends,
I am super stoked to share this video with you all! Triteia and myself haven teamed up with Hydrovane to field test an "Upcycled" unit.

I have long said that Hydrovanes are the BEST wind vanes on the planet so I and BEYOND excited to have on mounted on Triteia!

Two new engines within months of each other?! I made it to Fort Lauderdale and after a month I got my second new Nanni engine put into my boat. I sand my teak and wax my hull while waiting for the new exhaust system that still isn't ready.

Maupiti is one of the less visited islands in Society Islands group with a tricky narrow passage to get in & out. As we came with little expectations for this place we had a pleasure to discover local artist and visit his exquisite house. We also did some silly things and had to do repairs on Aquarius :(( Well to find out all of it you'll have to watch the video!

Thanks so much for watching 🙏

Zanzibar was absolutely amazing! Very different and rich of experiences, that we are so grateful for. It's both - historical & new. Old and trendy. Very different from the rest of Tanzania that we got to explore. SPICY!

In this episode, I hangout with fellow Youtube sailors from Ran Sailing and Sailing Uma, encounter the worst storm at anchor, nearly kill a dog, visit a pirates nest and Alsino's leg falls off.
Many thanks to Ran sailing for the drone footage.

Boat:
White Shadow is a Van De Stadt ‘Seal’ 36 (11 metres). She is hand made in steel, 2004, with a round bilge (hull) and a modified coach roof. This makes her a ‘one off’ and in my opinion the most beautiful Van De Stadt 36 ever built.

The camera gear:
Main camera is a Panasonic Hc-v700. Most shots are done with an external mic (Shenggu sg 108) with a sponge and dead kitten attached.
Action stuff and small blogging is done with a Sony Hdr-as30v.
Underwater video Gopro3plus.

Editing:
Final cut pro on a Macbook. Most of the material for each video is filmed over a period of several weeks or so and the editing of each episode is normally done over a day. This process can take longer if original music is used or permissions are needed for copyrighted materials etc. Much time is spent sorting out technical problems. In this case I normally get the help of a younger person who understands computerie stuff!
There are also times when filming, editing and uploading is not possible due to being at sea or in locations with no internet access.

Content:
I have found that filming and releasing material over a period of time is better than doing ‘vlog’ style videos and trying to make episodes out of whats happened in a week, regardless if it’s good content or not. By filming over a period of time I can be more selective in what goes into each video. My aim is to avoid ‘blar bar mundane’ and have at least one or two exciting and interesting events in every video. Every video has to be entertaining.

Comments and being at sea:
I love reading your comments. Most weeks Im able to read everyone. I cant reply to everybody but I do read and enjoy them. Keep them coming! There are times that It might seem I'm not on the internet for certain periods, this is normally when Im at sea on passage. While Im out on the Ocean I have completely no communications with the outside World.

Correction for the formula that I've shown:
Righting Lever (GZ) = GM x Sine0 ( Angle of Heel)
Righting Moment (RM) = GZ x Displacement

https://youtu.be/IM4HzhwvLDE
https://youtu.be/w6FBiW5hQGo
https://youtu.be/qoSrvcnvXTU

This animated video explains initial metacentric height, center of gravity, and buoyancy. It also shows how the ship floats and the three conditions of the ship's equilibrium. How the righting lever and righting moment were created, and how the angle of the loll formed.

The metacentric height (GM) of a ship is a crucial parameter that determines its stability characteristics, particularly its resistance to rolling motions in response to external forces such as waves, wind, and cargo shifting. It is a measure of the distance between the center of gravity (G) of a ship and its metacenter (M).

This video covers Radar motion displays. It shows the difference between True & Relation Motion with the ship's trails and vectors.

In True Motion, own ship moves across the radar screen in its true direction of movement, and targets move according to their actual paths. It displays the actual movement of both own ship and all targets relative to a fixed reference, usually the ground or earth. All stationary targets, such as landmasses, buoys, or anchored vessels remain fixed in position on the radar screen.

In Relative Motion display, all other targets appear to move relative to our ship. Even stationary targets, such as buoys, landmasses, or anchored vessels, appear to move relative to own ship's position.

This video explains the difference between Statical and Dynamical Stability. It focuses on the Righting lever at different angle of heels, Righting moment, and Area under the GZ curve.

Moment of Statical Stability or Righting Moment at any angle of heel is the moment that represents the ability of the ship to return to its initial position when heeled by external forces.

Dynamical stability defined as the work done in inclining the ship, or the energy required to heel a ship to a specific angle. It is quantified by the area under the righting arm known as the GZ curve up to that angle of heel.

This video contains the effect of a slack tank on a ship's stability. It explains how ships reduce their stability due to partially filled tanks as a result of the virtual loss of Metacentric Height (GM). It includes the calculation of the free surface moment, free surface correction, and applying FSC to determine the fluid GM.

Free surface effect refers to the influence of liquids in partially filled tanks or compartments on the stability of a floating vessel, such as a ship or a boat. When a vessel tilts or rolls, the liquid within these partially filled tanks tends to shift, leading to changes in the vessel's center of gravity and buoyancy.

This video explained how the ship's COG moves during loading, discharging, and shifting of weight on board and Its effect on the ship's KG and GM.

The ship's center of gravity (G) is the point within the ship where the entire weight of the vessel can be considered to act vertically downward. It is a fundamental concept in naval architecture and ship design, crucial for understanding a vessel's stability, trim, and overall seaworthiness.
