Estimate calories and kilojoules burned sailing — whether you're cruising at a relaxed pace on a keelboat, racing competitively, or hiking hard through a high-effort regatta — based on your body weight, sailing effort level, and time on the water. This calculator covers traditional boat sailing on dinghies, keelboats and yachts, not board sports like windsurfing or kitesurfing, which MegaCalcOnline covers on a separate calculator. Sailing has a genuine following in Australia through harbour and coastal yacht clubs in cities such as Sydney, Melbourne, Perth and Hobart.
Sailing calorie burn depends heavily on how hard you're working the boat, captured here as three tiers: leisure sailing (MET 3.3), competition sailing, general (MET 4.5), and competition sailing, high effort (MET 9.3). The formula is calories = MET × body weight (kg) × duration (hours). A 75 kg sailor spending 90 minutes (1.5 hours) on the water burns 371 kcal (about 1,553 kJ) at a leisurely pace, 506 kcal (about 2,118 kJ) racing at general competition effort, and 1,046 kcal (about 4,378 kJ) at high-effort competition sailing — nearly three times the energy burn between the easiest and hardest tier on this page.
| Effort Level | MET | Calories | Kilojoules |
|---|
The calculation uses a MET (Metabolic Equivalent of Task) value for your sailing effort level, your body weight, and the duration of your time on the water. This calculator uses three MET tiers taken directly from the sailing codes in the 2024 Adult Compendium of Physical Activities — leisure sailing (code 18140, MET 3.3), competition sailing, general (code 18130, MET 4.5), and competition sailing, high effort (code 18132, MET 9.3). All three values are literature-supported entries in the Compendium, not estimated figures.
| Effort Level | MET | Calories (75 kg, 90 min) | Kilojoules |
|---|---|---|---|
| Leisure sailing | 3.3 | 371 kcal | 1,553 kJ |
| Competition, general | 4.5 | 506 kcal | 2,118 kJ |
| Competition, high effort | 9.3 | 1,046 kcal | 4,378 kJ |
This calculator covers traditional boat sailing — dinghies, keelboats and yachts — where the sailor sits or stands inside a hull and controls the boat using sails, a tiller or wheel, and on racing boats, sheets and winches. It's a different activity from windsurfing and kitesurfing, where the rider stands directly on a board powered by a handheld sail or a flying kite, with no hull involved. The Compendium of Physical Activities lists these as separate categories with their own MET codes, and MegaCalcOnline maintains a dedicated windsurfing and kitesurfing calorie calculator for those board sports. Use this page for dinghies, keelboats and yachts, and the windsurfing calculator for board-based wind sports.
How much of a workout sailing turns out to be depends heavily on the boat, the conditions, and how hard you're racing it. Leisure sailing is mostly steering and occasional sail trimming, which keeps the physical demand fairly light. Competitive sailing adds regular tacking and gybing, repeated pulling on sheets and halyards, and constant small adjustments to keep the boat balanced and moving efficiently. At the high-effort end, crew are often hiking out hard or trapezing — bracing their body weight over the water to counteract the boat's heel — while grinding winches and trimming sails under real load, which works the core, legs, back and grip continuously and adds a sustained cardiovascular component across a race.
Sailing has a long-standing presence in Australia, with harbour and coastal yacht clubs found in cities such as Sydney, Melbourne, Perth and Hobart, alongside many further clubs along the coastline and on inland lakes and rivers. These clubs generally run a mix of club racing, cruising and learn-to-sail programs spanning a range of boat types — from small dinghies and skiffs through to keelboats and larger yachts — giving people of varying experience levels regular opportunities to get out on the water, whether purely for recreation or for structured racing.
The table below holds effort level constant at the competition, general tier (MET 4.5) for a full 60-minute sail, so you can see how much body weight alone changes the total.
| Body Weight | MET | Calories (60 min) | Kilojoules |
|---|---|---|---|
| 55 kg | 4.5 | 248 kcal | 1,036 kJ |
| 65 kg | 4.5 | 293 kcal | 1,224 kJ |
| 70 kg | 4.5 | 315 kcal | 1,318 kJ |
| 75 kg | 4.5 | 338 kcal | 1,412 kJ |
| 85 kg | 4.5 | 383 kcal | 1,600 kJ |
| 95 kg | 4.5 | 428 kcal | 1,789 kJ |
Here body weight is fixed at 75 kg while both time on the water and effort level change, so you can compare how much a harder tier and a longer sail each add to the total.
| Duration | Leisure (MET 3.3) | Competition, General (MET 4.5) | Competition, High Effort (MET 9.3) |
|---|---|---|---|
| 30 minutes | 124 kcal / 518 kJ | 169 kcal / 706 kJ | 349 kcal / 1,459 kJ |
| 45 minutes | 186 kcal / 777 kJ | 253 kcal / 1,059 kJ | 523 kcal / 2,189 kJ |
| 60 minutes | 248 kcal / 1,036 kJ | 338 kcal / 1,412 kJ | 698 kcal / 2,918 kJ |
Australian nutrition panels list energy in kilojoules, not calories, so it's worth converting your sail into the same unit your food packaging uses. Multiply your calorie figure by 4.184 to get kilojoules. A 75 kg sailor racing at general competition effort for 90 minutes burns about 506 kcal, which is roughly 2,118 kJ — a useful figure to weigh up against the energy value printed on a post-sail snack or meal.
How many calories does sailing burn?
It depends on how actively you're sailing. A 75 kg sailor spending 90 minutes on the water burns around 371 kcal at a leisurely pace (MET 3.3), around 506 kcal racing at general competition effort (MET 4.5), and around 1,046 kcal at high-effort competition sailing (MET 9.3). Lighter or heavier sailors, and shorter or longer sessions, will see proportionally lower or higher numbers, so use the calculator above with your own weight and time on the water for a personalised estimate.
What's the difference between leisure sailing, competition general, and competition high-effort on this calculator?
These three tiers come directly from the sailing codes in the 2024 Adult Compendium of Physical Activities. Leisure sailing (MET 3.3) covers relaxed sailing on dinghies, keelboats or yachts where you're mostly trimming sails and steering at an easy pace. Competition, general (MET 4.5) reflects the steadier physical demand of racing — tacking, gybing and hiking more regularly. Competition, high effort (MET 9.3) reflects hard-racing conditions where crew are hiking out hard, hauling on sheets and halyards under load, and moving their body weight around the boat continuously to keep it flat and fast.
Why does competitive or high-effort sailing burn so much more than leisure sailing?
The gap comes down to how much of your body weight you're moving and how hard your muscles are working to control the boat. Leisure sailing is mostly steering and occasional sail trimming, so the energy cost stays fairly low. Competitive sailing adds frequent tacking and gybing, and high-effort competitive sailing adds sustained hiking or trapezing — bracing your body weight out over the water to counterbalance the boat's heel — along with hard, repeated pulling on sheets and winches under real load. That sustained muscular effort against resistance, held for extended stretches of a race, is what pushes the MET value for high-effort competition sailing to roughly three times the leisure figure.
Is sailing a good workout?
Sailing can be a genuine workout, though how much of one depends heavily on the tier you're sailing at. Leisure sailing is fairly gentle and closer to light activity than a structured workout. Competitive sailing, especially at high effort with hiking, trapezing and constant sail trimming under load, engages the core, legs, back and grip strength continuously and adds a real cardiovascular component over the length of a race. Racing sailors, particularly on dinghies and smaller keelboats where crew weight directly affects performance, often build meaningful strength and endurance simply through regular time on the water.
Is sailing the same as windsurfing or kitesurfing?
No — this calculator covers traditional boat sailing on dinghies, keelboats and yachts, where you sit or stand in a hull and control the boat with sails, a tiller or wheel, and on racing boats, sheets and winches. Windsurfing and kitesurfing are board sports, where the rider stands directly on a board powered by a handheld sail or a kite and there's no hull to sit in. The two categories have different physical demands and different MET values in the Compendium, so if you're after windsurfing or kitesurfing, use MegaCalcOnline's dedicated windsurfing and kitesurfing calorie calculator instead of this page.
How do I convert calories burned sailing into kilojoules?
Multiply your calorie figure by 4.184, the standard conversion between kilocalories and kilojoules used on Australian food labels. A 75 kg sailor racing at general competition effort for 90 minutes burns about 506 kcal, which converts to roughly 2,118 kJ — a useful number to weigh against the energy value on a post-sail snack or meal.
Does body weight change how many calories sailing burns?
Yes. Because calories equal MET multiplied by body weight in kilograms multiplied by duration in hours, body weight is a direct multiplier in the formula. At general competition effort for a 60-minute race, an 85 kg sailor burns roughly 383 kcal compared with about 248 kcal for a 55 kg sailor completing the identical race at the identical effort level.
Does the type of boat — dinghy, keelboat or yacht — change how many calories sailing burns?
The Compendium's sailing MET values are grouped by effort level rather than by boat type, so the calculator applies the same MET figure regardless of whether you're on a small dinghy, a keelboat or a larger yacht. In practice, boat type does influence how physically demanding a session feels — smaller dinghies and skiffs typically call for more active hiking, trapezing and constant body-weight shifting, while cruising on a larger yacht is often closer to the leisure tier — so choose the tier that best matches how hard you were actually working the boat, rather than the boat's size alone.
Is sailing popular in Australia?
Sailing has a genuine presence in Australia, supported by harbour and coastal yacht clubs in cities such as Sydney, Melbourne, Perth and Hobart, along with many other clubs along the coastline and on inland waterways. These clubs typically offer racing, cruising, and learn-to-sail programs across a range of boat types, from small dinghies through to keelboats and larger yachts, giving both newcomers and experienced sailors regular opportunities to get out on the water.
