Glossary
The terms on every specification sheet, explained against this catalog.
Electric propulsion
- Battery capacity
What kWh means on an electric boat, why usable capacity differs from nominal, and what a buyer should ask for.
- Range at a stated speed
Why an electric boat's range only means something with a speed attached, and how to read the figure builders publish.
- Charging time
How long an electric boat takes to charge, what shore power actually delivers, and why the figure is so rarely published.
- Fast charging
What DC fast charging means on the water, why it is rare, and what to ask before counting on it.
- Motor power
What kW means on an electric boat, how it compares with horsepower, and why continuous and peak ratings differ.
- Outboard or inboard
The two ways an electric boat carries its motor, and what each one costs and buys.
- Hybrid electric
What hybrid means on a boat, how it differs from a pure-electric one, and why the distinction is often blurred.
- Solar electric boat
What solar panels actually contribute on a boat, and how to read a builder's solar figure.
- Range extender
What a range-extending generator does on an electric boat, and what it changes about the boat you are buying.
- LiFePO4 battery
The battery chemistry most electric boats use, and why it was chosen for the water.
- Hydrofoil
How foiling lifts a boat clear of the water, and why it suits electric propulsion particularly well.
Dimensions
- Length overall (LOA)
What length overall measures, what it excludes, and why almost every rule about a boat starts here.
- Beam
What beam measures on a boat, and what a wider or narrower hull buys you.
- Draught
How deep a boat sits, why shallow draught matters to electric boats in particular, and why so few builders publish it.
- Displacement
What a boat weighs, why the figure is quoted several different ways, and why weight rules an electric boat.
Types of boat
- Day boat
What a day boat is, and why the type suits electric propulsion better than any other.
- Sport boat
What makes a boat a sport boat, and the trade every electric one has to make.
- Electric catamaran
Why two hulls suit electric propulsion, and what a catamaran costs you in return.
- Tender
What a tender is for, and why electric tenders have become the default on larger vessels.
- Cruiser
What makes a boat a cruiser, and the questions an electric one has to answer.
