Electric vs Fuel: What It Really Costs to Ride a ROXEN in 2026

By the ROXEN Team · Updated March 2026

In short: At current prices, ROXEN costs approximately 1.1 EUR per hour to ride at cruising speed. A comparable petrol watercraft costs around 24.8 EUR per hour. Over a 50-hour season, that is a saving of roughly 1,180 EUR in fuel alone, before maintenance.

When comparing electric and petrol watercraft, the purchase price is only part of the picture. Running costs, maintenance, and long-term reliability all add up over a season. This guide uses current 2026 Swedish prices to show exactly what each option costs per hour and per season.

What Total Cost of Ownership Includes

Total cost of ownership looks beyond the sticker price. The main components are:

• Energy or fuel costs per hour of riding
• Routine service and replacement parts
• Long-term maintenance and component wear

Electric drivetrains have fewer moving parts and more predictable running costs. A petrol watercraft requires regular oil changes, impeller servicing, fuel system maintenance, and spark plug replacement. At cruising speed, it also burns significantly more energy per hour than an electric equivalent.

Energy Prices Used in This Comparison

All figures use current Swedish market prices as of March 2026:

• Petrol 95: €1.655 per litre (national average, week of 16 March 2026, source: European Commission Oil Bulletin)
• Electricity: €0.21–0.24 per kWh (residential rate, all-in including taxes and grid fees, based on Eurostat data and Swedish market forecasts for 2026)

Swedish electricity prices in 2026 are forecast to be stable to lower than 2025 in the southern half of the country, driven by good hydropower reservoir levels and expanded renewable production.

Cost Per Hour at 15–20 Knots

ROXEN (Electric)

ROXEN consumes 5.25 kWh per hour at 15–20 knots.

At the low end (€0.21/kWh): 5.25 × 0.21 = 1.10 EUR per hour At the high end (€0.24/kWh): 5.25 × 0.24 = 1.26 EUR per hour

Real-world range: 1.1 to 1.3 EUR per hour.

Traditional Petrol Watercraft

A typical petrol watercraft burns 10–25 litres per hour depending on model and speed. At a conservative 15 litres per hour at cruising speed:

15 L × €1.655 = 24.8 EUR per hour

Side-by-Side Comparison

ROXEN costs approximately 20 times less per hour in energy than a petrol watercraft at current Swedish prices.

What This Means Over a Season

For riders spending 40–60 hours on the water each summer:

ROXEN

• 40 hours: ~44 EUR
• 50 hours: ~55 EUR
• 60 hours: ~66 EUR

Petrol watercraft

• 40 hours: ~992 EUR
• 50 hours: ~1,240 EUR
• 60 hours: ~1,488 EUR

At 50 hours of riding, the energy saving alone is approximately 1,185 EUR per season. That is before factoring in the difference in maintenance costs.

Maintenance: Where the Gap Widens Further

Petrol watercraft require regular servicing that electric models do not:

• Engine oil and filter changes (typically annually or every 50 hours)
• Spark plug replacement
• Impeller inspection and replacement
• Fuel system maintenance
• Winterisation with fuel stabiliser

ROXEN's electric drivetrain has no oil, no spark plugs, no exhaust system, and no fuel circuit. The main ongoing tasks are battery care, post-ride rinse, and periodic software updates. Over several seasons, this difference in service costs compounds significantly.

Why Electric Running Costs Are More Stable

Petrol prices in Sweden have ranged from under €1.00/litre to over €2.30/litre in the past decade. Electricity prices are volatile too, but the all-in residential rate has historically been far less exposed to the spikes seen in global oil markets.

For 2026 specifically, Swedish electricity prices are forecast lower than 2025 in the south and stable in the north, driven by healthy hydropower reserves and continued renewable expansion. Petrol, meanwhile, is currently at €1.655/litre and trending upward week-on-week.

Frequently Asked Questions

How much does it cost to charge a ROXEN for one hour of riding? At current Swedish electricity prices of €0.21–0.24/kWh and a consumption of 5.25 kWh/hour, one hour of riding costs approximately 1.1–1.3 EUR in electricity.

How much does a petrol jet ski cost to run per hour? At 15 litres/hour and the current Swedish petrol price of €1.655/litre, running costs are approximately €24.80 per hour in fuel alone, before maintenance.

How much can I save per season by choosing ROXEN over petrol? At 50 hours of riding per season, the energy saving is roughly 1,185 EUR. Adding maintenance cost differences, total annual savings typically exceed 1,500 EUR.

Do electricity price changes significantly affect the comparison? Even at the upper end of Swedish residential electricity tariffs, ROXEN remains far cheaper to run than a petrol watercraft. The ratio only shifts meaningfully if petrol prices fall dramatically or electricity prices spike simultaneously.

Are these figures based on real data? Yes. Petrol prices are from the European Commission Oil Bulletin (16 March 2026). Electricity prices are based on Eurostat household data and 2026 Swedish market forecasts. ROXEN consumption figures are from manufacturer data at 15–20 knots.

Conclusion

At 2026 Swedish prices, ROXEN costs roughly 20 times less per hour to run than a comparable petrol watercraft. Over a full season, the energy saving alone typically exceeds 1,000 EUR. Combined with lower maintenance requirements and more predictable running costs, the total cost of ownership advantage is substantial.

The upfront price of an electric watercraft is higher. The running cost is not.
