One of the first surprises many sailors encounter is this:
The fastest boat doesn't always reach the destination first.
Wait... what?
How can a boat sailing at 7 knots lose to a boat sailing at 5 knots?
Welcome to the wonderful (and occasionally confusing) world of Velocity Made Good (VMG).
Whether you're cruising a modern sloop on a relaxing afternoon sail or trimming every inch of sailcloth during a regatta, understanding VMG can completely change how you think about getting from Point A to Point B.
The good news? The concept is simpler than it sounds.
And unlike some sailing topics, it doesn't require memorizing a dozen knots or deciphering cryptic weather charts.
🧭 What Is Velocity Made Good?
Velocity Made Good measures how quickly your boat is actually moving toward a specific destination.
Not how fast you're moving through the water. Not how impressive your speedometer looks. Not how much spray is flying over the bow.
Simply:
How fast are you closing the distance to your target?
That's VMG. Think of it as "progress speed."
Because at the end of the day, the goal isn't necessarily to sail fast... the goal is to arrive.
A Simple Example
Imagine you're sailing toward a harbor directly upwind. Your GPS shows:
- Boat Speed: 6 knots
Sounds fantastic. There's just one problem.
You're sailing 45 degrees off the direct course because sailboats can't sail directly into the wind.
Some of that speed is carrying you toward the harbor. Some of it is carrying you sideways.
Your actual progress toward the destination might only be 4.2 knots.
That 4.2 knots is your VMG.
In other words:
Boat speed tells you how fast you're moving. VMG tells you how fast you're getting there.
🌬️ Why VMG Matters Upwind
Upwind sailing is where VMG becomes especially important.
Many sailors make the mistake of pinching too high into the wind because it feels like they're heading directly toward their destination.
The result?
- Reduced boat speed
- Stalled sails
- Poor performance
Meanwhile, another boat may sail slightly lower, generate more power, and move significantly faster through the water.
Even though it appears to be taking a longer route, it may reach the windward mark first because its VMG is higher.
It's one of sailing's greatest paradoxes:
Sometimes you must point slightly away from your destination to reach it sooner.
🌊 VMG Matters Downwind Too
The same principle applies when sailing downwind.
Many sailors assume sailing directly toward a downwind destination must be the fastest route.
Not always.
A modern sloop often sails faster on a broad reach than dead downwind.
For example:
Boat A
Wing-on-wing:
- Boat Speed: 4 knots
Boat B
Broad Reach:
- Boat Speed: 6.5 knots
Although Boat B travels a longer path, its higher speed may produce a better VMG toward the destination.
That's why racers often zig-zag downwind instead of sailing straight at the mark.
They're chasing VMG, not simply heading.
☕ The Cruising Sailor's Approach
Now let's talk about the sailors who aren't trying to collect trophies. Imagine you're enjoying a leisurely weekend sail. The destination is a marina ten miles away.
You have:
- Good weather
- Plenty of daylight
- Fresh coffee in the cockpit
- No race committee timing your arrival
In this scenario, maximizing VMG may not be your highest priority. You might choose:
- A more comfortable point of sail
- Fewer maneuvers
- Less heeling
- A smoother ride for the crew
Sure, your VMG may be slightly lower.
But if everyone aboard is smiling and nobody is wearing their coffee, that's a pretty successful day on the water.
Cruising sailors often balance VMG with comfort, scenery, and enjoyment. And that's perfectly good seamanship.
🏁 The Regatta Sailor's Approach
Now let's move to race day. The start horn sounds. Suddenly everything changes. Now sailors are constantly evaluating:
- Boat speed
- Wind shifts
- Current
- Sail trim
- Course angles
- VMG
Racers aren't necessarily looking for the shortest route. They're looking for the route that produces the highest VMG. That might mean:
- Sailing slightly lower upwind for better speed
- Taking advantage of a wind shift
- Broad reaching downwind before jibing
- Constantly adjusting trim for maximum efficiency
Every decision is measured by one question:
Will this get us to the mark faster?
In racing, VMG often becomes one of the most important performance metrics aboard.
Modern Electronics Love VMG
Many modern chartplotters and sailing instruments display VMG automatically. These systems continuously calculate:
- Boat speed
- Course over ground
- Wind direction
- Bearing to destination
The result is real-time feedback showing whether your adjustments are helping or hurting your progress. It's like having a brutally honest sailing coach aboard. One that never takes a coffee break (we might be biased on this one).
The Real Lesson
VMG teaches a lesson that extends beyond sailing. The most direct path isn't always the fastest.
The most obvious choice isn't always the most effective. Sometimes making better progress requires a slightly different angle.
Whether you're cruising toward a quiet harbor or racing toward a windward mark, understanding VMG helps you make smarter decisions and sail more efficiently.
And once you start thinking in terms of VMG, you'll find yourself looking at the wind (and the water) a little differently.
Because sailing isn't just about moving. It's about making progress.
And that's exactly what Velocity Made Good measures.
