IRC vs ORC: Yacht Racing Handicap Systems Explained
IRC and ORC are the two main yacht racing handicap systems. IRC uses a single secret rating; ORC uses a transparent, science-based VPP model.

Line honours goes to the first boat across the finish line; the handicap winner is decided on corrected time — which is why one race can crown two winners.
Read the guideRacing explainedPHS and AMS Handicaps Explained (and How They Differ from IRC and ORC)
PHS adjusts a yacht's handicap on its recent results; AMS is a measurement handicap based on ORC data. Here is how both work alongside IRC and ORC in Australia.

A spinnaker hoist sets the downwind sail; a drop retrieves it. The string drop pulls the kite down a retrieval line for fast, controlled mark roundings.
Read the guideRacing explainedWhat Is Grand Prix Yacht Racing?
Grand Prix yacht racing is the top tier of inshore one-design and box-rule racing — carbon boats, professional crews and tactical windward-leeward courses.
Read the guideRacing explainedWhat Is One-Design Yacht Racing?
One-design yacht racing pits identical boats against each other, so results come down to crew skill, tactics and preparation — not boat speed.
Read the guideRacing explainedYacht Racing Crew Positions Explained
A Grand Prix racing yacht carries 8–10 specialists — helm, tactician, trimmers, pit, mast and bow — each with a defined job that wins races.

The Melges 40: Specs, Design and Sailing Characteristics
The Melges 40 is the only canting-keel production one-design yacht in the world — a ~12.2 m carbon Grand Prix racer designed by Botín Partners.
Read the guideThe boat & classWhat Is a Canting Keel and How Does It Work?
A canting keel is a yacht keel that swings from side to side to move ballast to windward, generating more righting moment for less weight — and a faster boat. Here is how it works, and why it is rare.

How Carbon-Fibre Race Boats Are Built
Carbon-fibre race boats are built by laminating carbon cloth and epoxy over a lightweight core inside a precision mould — maximum stiffness for minimum weight.

A fast yacht hull is light, slippery and shaped to either slice through the water or rise up and plane — balancing waterline length, beam and form against drag.

Sails of a Grand Prix Yacht: The Wardrobe Explained
A racing sail wardrobe is the full set of sails a yacht carries to match every wind angle and strength — here is how a modern North 3Di inventory works.

A spinnaker is the broad family of downwind sails; a gennaker is an asymmetric spinnaker flown from a bowsprit. Here is the difference and when each is used.

A square-top mainsail has a wide head for power and automatic gust relief; a pin-head main has a narrow, pointed head. Here is how the two compare.

The A1 is a light-air asymmetric spinnaker built for reaching — the lightest, flattest of the running sails, used to power a yacht up on tight, soft angles.
Read the guideSailsThe A2 Spinnaker: The All-Purpose Running Asymmetric
The A2 is a yacht's all-purpose running asymmetric spinnaker — a full, light-to-medium-air sail flown deep downwind to maximise speed made good towards the mark.
Read the guideSailsThe A3 Spinnaker: A Medium-to-Heavy Reaching Asymmetric
The A3 is a medium-to-heavy-air reaching asymmetric spinnaker — flatter and stronger than the light sails, built to power a yacht across the wind in a breeze.
Read the guideSailsThe A4 Spinnaker: A Heavy-Air Running Asymmetric
The A4 is a heavy-air running asymmetric spinnaker — a smaller, stronger, flatter-shouldered sail built to keep a yacht fast and stable running deep in a breeze.
Read the guideSailsThe Code 0: A Yacht's Light-Air Reaching Sail
A Code 0 is a flat, tightly cut reaching sail that bridges the gap between upwind jibs and downwind spinnakers — built for light air and tight reaching angles.

The J1 is a yacht's largest, lightest headsail — the number one jib, set in light to moderate winds for maximum power and pointing upwind.
Read the guideSailsThe J2: A Yacht's Medium-Air Number Two Jib
The J2 is a yacht's medium-air headsail — the number two jib, flatter and smaller than the J1, set as the breeze builds beyond the light-air range.
Read the guideSailsThe J3: A Yacht's Heavy-Air Number Three Jib
The J3 is a yacht's heavy-air headsail — the number three jib, small and flat with a high clew, set in strong winds to keep the boat fast and on its feet.
