Start with the BOWREX Introductory Bundle.
BOWREX is a deployable external bow thruster system for sailboats —
a compact mini tug for the bow, built for serious short-burst docking assistance.
The current BOWREX-supplied project package is focused on five main items:
Main Thruster Housing, Upper Lever Arm,
Rear Straight Vane, Pulley Hoisting Handle,
and Smart Control Board Set.
Together, these parts create a strong and practical starting system for a BOWREX deployable mini tug build.
Carry it on board. Deploy it for docking. Retrieve it after use.
Compatible manufacturer-sourced components
Motor, ESC, anti-spark switch, propeller, and remote controller are compatible
manufacturer-sourced components. Use the links as references and enter the current
prices you find. These amounts are for planning only and are not charged by BOWREX.
Because BOWREX is intended for serious short-burst thrust, component selection matters.
Confirm exact compatibility before ordering.

Recommended battery cell direction
The battery is the main builder-selected item. BOWREX recommends a 14S4P battery direction using high-performance 21700 cells.
- Ampace JP40: recommended high-current cell option for a practical 14S4P BOWREX battery build.

Final battery pack design, BMS/charging method, enclosure, wiring, connector choice, and marine-safe installation are the builder’s responsibility unless specifically stated.

Estimate summary
This page is designed to help customers understand the full path from the BOWREX Platform to a complete BOWREX system. BOWREX checkout, manufacturer-sourced parts, and the builder-selected battery is shown separately. No combined grand total is shown because outside supplier items are not purchased through BOWREX.
