Coxmate Systems
The Coxmate range of electronic assistants for coxswains brings modern electronics technology to coxing amplification and speed measurement. The Coxmate designs are the result of a lengthy and intensive study into the needs of rowing, and how existing systems can be improved.
Got questions...? Check out our Coxmate FAQ page, if you have other questions, please e-mail us, we'll be more than happy to answer your questions.
Under the WEEE regulations, Rowperfect UK will recycle your old electronic Coxmate products and ensure they are not sent to landfill. You must return your old Coxmate to us within 28 days of buying a new one and we can only exchange on a like-for-like basis. This means an HC is not exchangable for an SRT+.
Coxless Boats Non-Audio Units
The Coxmate HC is our latest innovation and is designed specifically for coxless boats.
Lighter and compact, it mounts into your boat on a wiring loom that includes a neat on/off switch as well as magnetic pick-ups for rating and the speed impeller.

Coxed Boats Audio Amplifier Units
We provide amplification systems, speed measurement and wiring looms with speakers for coxed boats.
There are three levels of coxing amplification system:

Coxmate SCT
Coxmate SCT GPS sensor SC Impeller
The Coxmate SCT is the most sophisticated of all the rowing amplifier units on the market. The unit displays: rating, stroke count, time and has recording capabilities. The optional speed sensor provides additional information on: speed, distance, cover (distance per stroke), speed ratio* (min/max speed per stroke), average speed and a PACE boat function. The optional Coxmate Analysis Software enables rowing data to be transferred to a PC and analysed.
The SCT has considerable storage and processing capability. To allow users to benefit from future developments, it is capable of having new versions of software downloaded over the Internet. The software allows a synchronised image of both the velocity profile of the boat and a video of the rower(s) to be displayed concurrently. The SCT is available with magnetic mounting or conventional connectors.
Speed measurement is effected in one of two ways either with a speed sensor and impeller mounted under the hull and wired into the SCT unit to provide the speed data. Or with a GPS pick-up mounted behind the coxswain.
Different lengths of speed sensor cable are available for 4s and 8s and bow- and stern-coxed boats. The impeller is in a fully enclosed mounting thus protecting it somewhat from water borne debris.
Using a GPS sensor, only enables land speed to be recorded. Stroke profile data is not possible because of the frequency of data upload (approx 0.8 secs). Using the speed sensor and impeller, the software records a graph of each stroke taken. More detail on speed measurement options.
Note: You will need a SCT plus either a GPS or Speed sensor cable and PC software. The SCT Kit includes mounting bracket, battery charger, carry case and syringe of silicone grease. [it does not include GPS. speed sensor, software, wiring loom or speakers]. Buy Coxmate SCT now.

Coxmate SRT
The Coxmate SRT+ contains an audio amplifier, stroke rate indicator and stopwatch. It is designed for durability and ease of use.
It has a tough ABS waterproof box and is supplied with an adjustable bracket using a unique magnetic mounting system.* This simplifies fitting the unit into the boat and enables position and angle adjustment. It does away with the problems caused by frequent operation of the 4 pin rubber connectors (broken wires, loose connections); it takes less than a second to fit the SRT into the boat. An alternative rubber-connection option is also available and includes the articulated bracket and an NK cup-adapter. The microphone connects to the SRT with a robust waterproof jack-type plug. A radio input jack is provided as standard for coaches to speak direct to the crew with a radio handset.
This coxing amplifier uses the latest digital technology and battery life is around 60% longer lasting up to 15 hours - that's five outings! The battery automatically powers down if the speakers are disconnected. Volume settings are automatically remembered between outings.
All Coxmate products are fully compatible with commonly used rowing boat wiring systems.

Coxmate AA
Coxmate AA circular plug for round mould (shown with AA mounting plate attached)
The Coxmate AA is an audio-only model. It has been designed to be durable and low cost.
All Coxmate products are fully compatible with commonly used rowing boat wiring systems.
The AA has a large capacity rechargeable battery storage with a sophisticated battery management system to increase battery life. The unit can be left permanently connected to the charger, as it turns the charger off once batteries are full. This prevents degradation of the batteries. There is also a low level battery warning and charge full indicator.
Compared to competing products, the Coxmate AA has increased audio power which reduces distortion, increases efficiency and battery operating time. Volume settings are remembered between outings and the microphone connection to the control box is permanent – removing problems associated with unreliable connection. Buy Coxmate AA now .

PC Analysis Software
The PC software package enables data collected by the SCT and HC to be uploaded to a PC and analysed. The package includes software CD, an adaptor for connecting to SCT or HC (specify) with a D9 serial connector and a serial-USB converter.
Features Include
- Automatic time and date stamping of records
- Ability to annotate records with details of crew, weather, etc
- Graphing ability of up to four variables, plotted against either: time, distance or stroke count
- Graphing ability for up to four records, as either a single chart or four separate graphs
- Zoom for precise reading of any point on graph
- Display synchronized video on screen with dynamic graph.
The following graphs show some of the functions of the software:
Wiring Loom and Speakers
Coxmate Loom
Coxmate Wiring Loom accommodates up to 4 speakers in an eight – providing even sound volume throughout the boat, and enabling the cox to communicate with his crew but not the competing crew alongside! This allows four speakers for an eight and two speakers for a four. The wiring is modular enabling each speaker section to be separately tested and maintained.
They are more robust than other designs, the speakers are smaller and mount flush with the boat (no bracket to bend) and the sound quality is higher. Boat Classes & loom options
The wiring loom design includes:- All connectors are fitted with metal clamps for strain relief (protects against damage during connection/disconnection).
- The wiring is modular and so if one speaker fails, it is easy to replace that section alone.
- Speakers are slim, waterproof and mounted directly onto the boat without brackets thus maintaining direction of sound.
- All cables are double insulated to provide additional mechanical protection.
- All copper wires are tinned to reduce corrosion.
- All connectors are fitted with visual markers to assist in aligning of two halves during connection - "join the yellow dots".
- Main connector is fitted with a retentive cap. This is used to protect connector when it is disconnected from the control unit.
All poplular cox amplification systems can be used with Coxmate wiring looms. The fitments to join the wires are the same and they are fully compatible.
Having concern for maintaining the watertight sealed compartments in modern rowing boats, Coxmate offers sealing glands so that you can retro-fit Coxmate Wiring Looms to your existing boat fleet. The Coxmate Glands are supplied in two parts, Split cable gland insert and retainer. This enables you to unseal the gland at a later date if you need to get into the sealed compartment or replace part of the modular harness. No expoxy permanent glue required. This is a special order. Please contact Rowperfect .
A split cable gland for sealing cables through bulkheads. This has two parts: a retainer which is epoxied into bulkhead (a hole between 27 and 32mm diameter is required.) The cables can then be fitted into split gland – without removing connectors and the gland pushed into retainer. The gland will take up to 2x 5mm, 1x4.5mm, 1x4mm, 1x3.6mm and 1x2.5mm diameter cables. The gland can be fitted without the retainer – it requires a 25mm hole.
