E10

Who it suits

The E10 measures ten metres, with three metres of beam and around 2,800 kg — a striking set of numbers, and the weight is the interesting one. It is what makes the published 86 nm range credible at a 5.4 to 7-knot cruise, and what allows a top speed approaching 19 knots without an enormous drivetrain. The fast-displacement hull by Jaap de Jonge, with Mulder Design styling and a JR Yachts build behind it, points squarely at the Dutch and German inland owner who wants a long, quiet, elegant day boat rather than accommodation.

The gaps, and the trailer question

The yard does not disclose the motor or battery brand, nor the pack capacity. For a boat sold substantially on its range, that is a significant omission: without kilowatt hours you cannot sanity-check the range claim, compare it against rivals, estimate charging time from a given supply, or budget for eventual pack replacement. No price is published either.

The trailerability claim also needs qualifying. At 3 m beam the E10 is wider than the 2.55 m allowed for unrestricted road transport across most of Europe, so towing it between lakes and countries means abnormal-load permits and the conditions attached to them, not simply hitching up and driving. That is manageable for a determined owner, but it is not casual trailering, and the cost and paperwork should be factored in.
