NetZero Marine designs vessel-specific electric propulsion and onboard energy systems for recreational sailboats. We begin with how you use your boat, then develop a conversion approach around its hull, drive train, space, range, charging, and operating needs.

Electric sailboat repowers, designed around the vessel.

Quiet and clean power. Practical range. Designed for real use.

Practical electric propulsion for sailing yachts

Electric Repowers

Explore how motor selection, drive arrangement, batteries, and charging come together around your boat and typical motoring needs.

Your existing propulsion system is the starting point for assessment.

Energy Systems

An energy system designed around life aboard. Explore battery storage, charging, shore power, solar, monitoring, and electrical integration—and how they support propulsion and onboard use.

Vessel- and usage-specific design

Every conversion begins with the boat.

An electric repower is not a generic engine swap. The right system depends on the hull, displacement, existing drive train, propeller, engine-room layout, usable battery space, weight distribution, charging opportunities, and the way you actually cruise.

NetZero Marine starts with those realities. The goal is practical maneuvering authority, useful motoring performance, safe system integration, and an energy plan that suits the vessel and its intended use—not an attractive specification that works only on paper.

Every assessment considers:

  • Hull displacement

  • Existing shaft, saildrive, or outboard drive arrangement

  • Battery space, weight distribution, and service accessibility

  • Typical motoring patterns, hours, and range

  • Shore power, solar, hydro regeneration, wind, and other charging opportunities

A CLEAR PROCESS

From first conversation to sea trial

An electric repower should be practical, transparent, and built around the way you sail. We take a structured approach from initial assessment through commissioning and early operation.

01

Conversion Assessment

We review your sailboat, present propulsion, normal cruising pattern, objectives, and practical constraints.

02

Preliminary Concept

We identify a likely propulsion, energy-storage, and charging direction, with the key trade-offs clearly explained.

03

Detailed Scope and Installation

We refine the specification, coordinate equipment and work, and integrate the system for safe, serviceable operation.

04

Commissioning & Support

We test the system, document normal operation, and support you through the initial operating period.

NEXT STEP

Start with a Conversion Assessment

Tell us about your sailboat, current propulsion, typical cruising, location, and goals. We will help determine whether an electric repower is a sensible next step and what information is needed to develop a preliminary concept.
