True North and Magnetic North

There’s a North Pole, where Santa lives stuck in the ground and secondly, there’s a Magnetic North, where the magnets live our steering compasses, and our handheld compasses are magnetic devices, and they point towards magnetic north not True North. However, our charts are all orientated to True North. The resulting angle between magnetic north, and true north is what we call variation and it will change according to where you are on the planet. So why do we do this? Why don’t we just orient our magnet and be done with it orientated towards the North Pole? True North because it’s a fixed position on the globe and it doesn’t move. However,…

Magnetic North vs True North: Understanding Variation and Deviation in Navigation

True North and Magnetic North In the world of navigation, two terms often get tossed around: true north and magnetic north. While they sound similar, they're not exactly the same. Understanding the difference between them is crucial for accurate navigation, especially when relying on a compass. True North True north refers to the fixed point on Earth's axis around which the planet spins. It's like a giant bullseye at the top of the globe. Magnetic north, on the other hand, is the direction the compass needle points. It's not fixed and can vary depending on your location on Earth. This difference between true north and magnetic north is called variation. Maps and directions…

How to Trim Mainsail to Make your Sailboat Go Faster!

When we look to trimming our mainsail, we really do need to understand the principles of sail twist and why sail twist is so important. As your boat sails along, the wind hitting the top of the sail is a little bit stronger than the wind hitting the bottom of the sail. For this reason, the top of the sail needs to be slightly looser than the bottom. This is where sail twist comes in. By using the mainsheet, the traveller, and the vang, depending on the point of sail, we can get air to move smoothly and drive the boat across all points of that mainsail. This will lead you to have…
