🖌️ ZEROJET TENDER

The OC350 is a 3.51 m rigid-hull tender produced by OC Tenders in partnership with ZeroJet. The hull combines carbon and fibreglass laminate for low mass and high stiffness. Beam measures 1.60 m, overall weight is 139 kg, and the craft carries 448 kg of people and gear.

A sealed 48 V jet unit delivers 14 kW (20 hp equivalent). The drive package weighs 40 kg and mounts flush inside the transom, leaving no exposed propeller.

Two battery options—5 kWh or 10 kWh LiFePO₄ packs—slide under the gunwales. Top speed reaches 20 kn. The 10 kWh pack supports 75 min at full throttle or 27 nm at displacement speed; the 5 kWh pack halves endurance. A fan-cooled charger restores the 5 kWh pack in roughly two hours.

Standard equipment lists an LCD state-of-charge display, electronic throttle, reverse bucket, automatic bilge pump, kill-cord lanyard, and davit lifting eyes. The jet’s shallow draft allows beach landings, and the hull planes at 10 kn with two adults aboard.

ZeroJet and OC Tenders build the OC350 in Auckland for yacht owners and coastal patrol operators seeking a light, emission-free workboat. The model slots into tender garages sized for 3–4 m inflatables while removing the hazards of petrol storage and propeller strike.

🌊 ELECTRIC PWC

E-Dolphin’s S300 is a two-seat electric personal watercraft that rides on a carbon-fibre hull for low weight and high stiffness. A sealed 30 kWh lithium-ion battery sits low in the hull and feeds a 120 kW permanent-magnet motor that turns a direct-drive jet pump, removing belts and gearboxes. The result is near-silent thrust that pushes the 3 m craft onto plane in seconds and carries it to about 50 knots (90 km h). In steady cruising the pack supports close to two hours on the water; continuous sport riding shortens run time to roughly one hour.

Charging infrastructure was a core design goal. A CCS port restores the battery to 80 percent in under thirty minutes with a marine DC fast charger, while a Type 2 connection on the same port delivers a full charge in about two and a half hours from a 220-volt pedestal. Overnight top-ups remain possible from a household outlet. Integrated battery management balances cells and controls temperature to protect cycle life, and the propulsion system meets CE and IEC marine safety standards.

At 1.2 m across the beam the S300 handles like a mid-size gasoline ski but runs without exhaust fumes or engine noise. Bow volume holds fifty litres of dry storage for lines and gear, and the deck includes navigation lights, a recessed cleat, and optional tie-downs for yacht-tender duty. A sealed digital dash shows remaining energy, range at current speed, and selectable ride modes.

The company behind the craft was founded in Hyères, France, by Nicolas Florès, an engineer who left the electric-vehicle sector in 2018 after years of coastal riding showed him the impact of combustion noise and fuel discharge. E-Dolphin operates with a staff of fewer than fifty and holds patents on its battery enclosure and drive system. Seven years of in-house research led to the S300 prototype, and the firm now frames its mission around the mantra “Play, Protect & Respect.”

First production units are set for Q3 2025, with an initial run of fifty craft aimed at European rental fleets and yacht owners. E-Dolphin plans to scale to about one thousand units per year within five years and to add North American and Asian distribution once European demand is secure. Each S300 leaves the factory with a two-year warranty that covers the battery, drive unit, and structure, plus an optional service plan that provides annual inspection, software updates, and battery health reports.

📅 EBOAT MOMENTUM

Here is a series of snapshots of electric-boat momentum:

• Market acceleration – Analysts see the sector jumping from ≈ US $6 B in 2025 to ≈ US $20 B by 2035 (≈ 11.6 % CAGR), as battery prices fall and marinas add charging (Link).

• Big-brand buy-in – Frauscher’s new 8.7 m x Porsche “Fantom Air” (400 kW, 95 mph, 800 V fast-charge) shows premium auto makers view e-boats as a halo product (Link).

• Capital still flowing – Candela’s €24.5 M round and other 2024 deals (e.g., X Shore) keep R-&-D pipelines funded for foiling craft and commercial ferries (Link).

• Battery leap – New marine-rated solid-state packs (≈ 240 Wh kg⁻¹) from Solid State Marine and Sealence promise lighter installations and sub-30-min re-charges (Link).

• Repower focus – Affordable 10–25 kW outboards (EClass, Mercury Avator, ePropulsion) are surging, as owners electrify existing hulls before buying new boats (Link).

• Policy pull – The EU’s 2024 extension of its Emissions Trading System to maritime CO₂ is nudging builders and charter fleets toward zero-emission options (Link).

⚙️SOCIAL MEDIA POST OF THE WEEK

We are guessing this foreshadows an attempt later this Summer to break the speed record for an electric boat.
