Model your 80 Eco
Pre-filled with Sunreef 80 Eco figures. Crew count and engine hours move the total more than anything else on this page.
The yacht
Length drives dockage; value drives insurance and refit reserve.
Crew
Above roughly 80 feet, crew becomes the single largest running cost.
Zero for an owner-operated boat.
A further 30% is added for payroll tax, insurance, and provisioning.
Berth, insurance & refit
Insurance and refit reserve are struck against the declining hull value.
Reduce if the yacht cruises or lies at anchor for part of the year.
Covers haul-out, paint, systems, and the periodic refit.
Fuel
Wildly variable — a planing hull at speed burns many times what it does at displacement speed.

Where the money goes
Fuel is nearly irrelevant, which removes the most volatile cost line. Catamarans also charter exceptionally well because of the deck space, so offset revenue is stronger than for a monohull of similar value.

Sunreef 80 Eco — common questions
- How much does it cost to run a Sunreef 80 Eco per year?
- Excluding depreciation, roughly $677,160 per year — about 8.7% of the $7,800,000 purchase price, against the industry rule of thumb of 10%. That breaks down as approximately $226,200 crew, $49,920 dockage, $86,190 insurance, $298,350 maintenance and refit reserve, and $16,500 fuel at 250 engine hours.
- What is the true cost of owning a Sunreef 80 Eco?
- Including depreciation, the Sunreef 80 Eco is modeled at about $1,200,072 per year over five years — roughly $100,006 per month. Depreciation alone accounts for 48% of that, which is why the purchase price is the smaller half of the decision.
- Is it cheaper to charter a Sunreef 80 Eco than own one?
- At 6 weeks aboard per year, chartering is substantially cheaper. A comparable charter runs about $124,960 per week including APA and extras, so 6 weeks costs roughly $749,760 against $1,200,072 to own. Ownership only wins beyond about 10 weeks aboard per year.
- How much does a Sunreef 80 Eco depreciate?
- The Sunreef 80 Eco is modeled to retain about 72% of its value after three years and 63% after five — a loss of roughly $2,886,000 over the five-year hold. Fuel is nearly irrelevant, which removes the most volatile cost line. Catamarans also charter exceptionally well because of the deck space, so offset revenue is stronger than for a monohull of similar value.
- How many crew does a Sunreef 80 Eco need?
- Approximately 3 full-time crew. At an average salary of $58,000 plus payroll taxes, insurance, training, and provisioning, that is about $226,200 per year — 33% of the total running cost.
