Respiro

A launch, in the traditional sense

The proportions tell you what the Respiro is. Nearly seven metres long on a 1.9-metre beam is a slender, low-drag launch shape rather than a modern beamy day boat — the hull is designed to slip through the water on very little power, which is why 4 kW is enough for 8 knots on a boat this length. That efficiency is the whole design argument, and it suits Italian lakes, lagoons and canals precisely.

The Harmo drivetrain

Venmar fits Yamaha's Harmo rim-drive electric outboard, a ducted, propeller-in-ring unit rather than a conventional shaft and prop. Note that Harmo is the motor, not a second Venmar model — the names appear together often enough to confuse. The practical benefit is a compact, quiet installation with good low-speed manoeuvrability; the practical constraint is that a 4 kW rating leaves no headroom for wind or current, so the Respiro is a sheltered-water boat.

What is missing

No battery capacity is published, and without it no endurance figure can be inferred — the single most important question to put to the yard, alongside charge time and whether the battery is included in the price, which is also unpublished. Buyers wanting five seats and elegance on a calm lake will find little else this efficient; anyone facing chop or a schedule should look at a beamier, more powerful hull.
