eFoil vs Jet Ski
The jet ski had a forty-year run as the default toy on every yacht's swim platform. The eFoil has, in three short seasons, ended that.
The comparison is unfair, in some sense — these are different machines with different purposes. But they compete for the same space: the corner of the swim platform, the line item on the charter inventory, the half-hour after lunch when the guests want something to do. And on every relevant metric for that competition, the eFoil now wins.
Wake
A jet ski throws a substantial wake — destabilising for swimmers, damaging to anchored tenders. An eFoil produces almost no wake at all. It can ride past a swimming child without disturbing the water.
Environmental impact
A typical hour on a petrol jet ski burns roughly 25 litres of fuel and discharges measurable hydrocarbons into the water. An eFoil at cruise consumes about 1.5 kWh — generated, in many marina contexts, from solar.
Noise
A jet ski at full throttle measures around 90 decibels at the helm. An eFoil at cruise measures under 50 — quieter than a normal conversation. For neighbouring vessels, the difference is the difference between welcome and unwelcome.
Cost of ownership
Jet ski: roughly €18,000 to buy, €3,000 per season to run and service. eFoil: €11,000-€19,000 to buy, under €500 per season to maintain (mostly battery cycle replacement). The eFoil is cheaper to own beyond year three.
The verdict
For nearly every use case that historically belonged to the jet ski — yacht toy, family entertainment, dockside recreation — the eFoil is now the better choice. The jet ski retains an edge in raw passenger capacity (it carries two; the eFoil one) and in pure top-end speed. Beyond that, the case is closed.
Skill curve
A jet ski is faster to learn — most guests are riding within five minutes. An eFoil takes three to four sessions. But the eFoil rewards mastery in a way that the jet ski does not; ownership is more interesting over years.
