7米、2吨帆船的电动吊舱改装案例研究：从 6 马力舷外机到 3 千瓦 ePropulsion 3.0 Evo

The 7m, roughly 2-tonne sailboat received a 3 kW ePropulsion 3.0 Evo pod drive mounted on the centerline under the hull, replacing the previous 6 HP outboard; the installation required reinforcement of the sole with 20 mm marine plywood epoxy-bonded between two stringers to distribute the concentrated propulsion loads and protect against grounding impacts.

Pod installation and structural considerations

Installing the pod beneath the hull, longitudinally aligned and parallel to the waterline, optimizes thrust and minimizes parasitic vibration. This configuration concentrates mechanical forces at one fixed point, so local strengthening was mandatory: the floor in the former engine bay was rebuilt on a 20 mm marine-plywood bed, saturated with epoxy to prevent long-term warping and supported by two varangues.

Alignment and mounting details included short, protected cable runs and placing the charger close to the batteries for service access. The entire retrofit, beyond planning, was executed in approximately ten hours of hands-on work.

Installation checklist (at a glance)

• Pod: ePropulsion 3.0 Evo (3 kW), centerline mount
• Hull reinforcement: 20 mm marine plywood between two stringers
• Battery pack: two E60 units (~6 kWh total)
• Battery placement: former engine compartment under companionway
• Charger: mounted above batteries with short wiring
• Epoxy saturation of supports to prevent warping

Batteries and electrical architecture

The electrical system is built around two E60 batteries delivering roughly 6 kWh of usable capacity. The pack sits on the reinforced 20 mm plywood floor and is secured to two varangues. Wiring is routed for minimal length and maximum protection, and the charger occupies an accessible position above the battery bank.

Practical notes: solar input is reserved for auxiliary services, and hydro-generation below 5 knots proved marginal during testing—expect limited replenishment from passage alone.

Power, speed and range — sea-trial data

解释

在 1,500 W the boat reaches near hull speed with good efficiency—about 25% battery capacity per hour. Doubling to 3,000 W yields only a modest speed gain while dramatically reducing range: beyond this point the energy cost per additional knot becomes unfavorable.

Cruising feedback and itinerary implications

Over a week-long cruise from Arradon calling at Hoedic 和 Belle-Ile and returning to the Gulf, the sailboat recorded ~82 miles sailed while motoring only two effective hours (approximately 8 miles). Total battery consumption for the week was roughly 50%, with one hour for harbour manoeuvres and one hour to secure arrival before a tidal reversal—the remainder was under sail.

For coastal touring: the combination of quiet electric propulsion and conservative power sizing supports a sailing-first itinerary, but planners should factor in limited motoring reserves for adverse wind or tidal conditions.

Limitations and recommended redundancy

• Energy reserve risk: strong headwinds or current can exceed stored capacity.
• Backup: carry a small 2,000 W generator for emergency recharging.
• 再生： 水力发电在 5 节以下时很小；不要依赖它进行持续充电。.

电力推进如何重塑巡航体验

电力牵引改变日常生活： 近乎静音，瞬间扭矩实现精准操控，无需车载燃油, ，并减少年度机械维护。对于来访的客人和一日游包船乘客来说，安静地驶入港口以及缺乏震动，能带来更轻松的抵达体验和更适合拍照的体验——请注意，这对于计划举办游艇派对或短途巡航套餐的运营商来说非常重要。在像Pizzicato这样的轻型巡洋舰上，安装是一种有意识的权衡：优先考虑沿海航行，并接受可控的、非过度的电机功率。.

转换不仅仅局限于硬件：它需要重新思考物流——充电策略、港口服务和备用燃料计划——所有这些都直接关系到旅行计划以及运营商可以提供的体验类型。.
