Yes — and that’s the wrong question to stop on. You can drive this boat at 6 knots. What matters is what 6 knots costs, because the price in power is not linear, and pretending otherwise is how people end up with range anxiety and a flat bank.
Hull drag climbs with the cube of speed. Ask for a little more boat speed and the power demand doesn’t nudge up — it wall. That cubic wall is the single fact most first-time electric owners haven’t internalised, and it’s the exact thing our configurator was built to make visible. The whole point is that you should see the curve before you buy, not discover it offshore.
Here’s where the wall bites. At 2.5–3.5 knots SV Endurance draws between 200 W and 1 kW — a load the solar array can sustainably match in daylight. Push to a diesel-style 4.2 knots and the draw is already around 3 kW. Every fraction of a knot above that costs disproportionately more, until you’re spending the bank far faster than the sun can refill it. Six knots is available; it is simply expensive, and it’s honest to say so.
Which is why we don’t sell speed — we sell predictability. Competitors sell you a motor and a top speed; we sell you the honest power-speed-range curve for your hull, so the boat behaves exactly as the numbers said it would. For most passages the win isn’t going faster, it’s knowing precisely what a chosen speed does to your range and your reserve.
And for the day you genuinely need to punch through — a hard chop, a foul current — that’s a planned exception, not a daily habit; keeping a backup aboard for exactly those moments is a choice we’ll talk through openly.
