The current practice of fitting tracker devices to towed tenders has come under pressure due to the increasing size and value of tenders, the increased levels of claims, and the increased restrictions in insurance cover.
Advances in technology now raise the level of tow protection available and establish a new standard industry practice – helping captains prevent losses in the first place and reduce claims.

“The towing of tenders and chase boats has become a major area of concern for marine underwriters in recent years, and we, along with our Risk Management experts, have worked closely with TSM Systems in creating TowPro, a system we believe will significantly reduce the concerns of Owners, Captains and Insurers alike”.

‘Eyes in the boat’
TowPro gives captains peace of mind at a glance
Key safety data are displayed live:
- Bilge water levels
- Bilge pump run times
- Battery health
- Tow stability: surging and yawing
- Tender stability: pitching and rolling
TowPro helps bridge crew spot problems fast
Captains can set TowPro to give instant alerts when safety data exceeds acceptable levels.
The alerts prompt bridge crew to investigate the problem, and take precautionary action if required to prevent incidents occurring.
In this example, the captain accepts that an automatic bilge pump might run for 3 minutes per hour to remove spray, etc, but wants an alert if it runs for longer.
Automatic ‘adrift’ protection
TowPro provides comprehensive protection – automatically
TowPro continuously monitors the tow length. If the
tow fails, TowPro automatically activates:
- Emergency AIS broadcast to nearby shipping
- Hourly iridium reports to tracking website
- COLREG required ‘Not under command’ lights

Eyes in the boat whenever you are towing
TowPro tells you exactly what is happening in your tow, and warns you immediately if something happens that might be a risk, for example: rising bilge water level, bilge pump activity, over-running the towline causing snatch loads, rolling heavily and vulnerable to shipping water.
Why do I need TowPro when I already have a tender tracker?
Tracking your tender once it’s adrift is too late. You really don’t want to lose it in the first place; that’s what TowPro helps you to avoid. Because it constantly monitors a number of key indicators about your tow on the bridge of the yacht, it is the only product able to flag up danger signals to you instantly. TowPro is a key part of the Advanced Tow Protection initiative, which is the result of a year-long cross-industry collaboration between captains, insurers, risk assessors, naval architects, hydrodynamic stability experts and installers, with patents filed internationally.
TowPro protects you throughout the tow, as well as tracking
If despite best efforts you do lose your tow, TowPro makes you aware immediately, and incorporates world-leading tracking, which maximises the opportunity to recover the tender. The tracking not only makes the tender visible on AIS to vessels nearby, but also reports to a global tracking website to help later recovery.
And what’s more, it’s simple to install, low cost to run, and easy to use
TowPro is designed for simple plug and play installation, and avoids the complexity of any connection to the yacht’s networks. Most importantly TowPro shares an existing antenna on the superyacht, so there’s no need to run cables and install a new one.
TowPro uses free-of-charge VHF to send safety data to the yacht, so there are no monthly satellite bills to pay. And it’s intuitive to use: a colour touchscreen on the bridge provides you with the information, and alerts you when action is needed.
Once TowPro is onboard, it will monitor the full duration of the tow, day and night.
So, install a TowPro as soon as you can. With the device onboard, you won’t have to worry about disruption to owners or guests, or suffer the additional pressure caused by a lost or damaged tender, and potentially expensive damage to the yacht.
Compliant with IMO regulation
AIS is regulated as a SOLAS system for collision avoidance, and therefore IMO regulations expressly prohibit the common practice of using an AIS tracker on a towed vessel. TowPro makes the captain compliant by using the new VHF Data Exchange System throughout the tow, to send safety data and to display the tow position on the electronic chart display.
Low running costs
The DataTraq radio uses the free-of-charge VDES system in normal operation, removing the cost of monthly satellite data charges. If the tender goes adrift, DataTraq uses an emergency tracking website via Iridium, to enable authorised users to keep a close watch. This emergency service is provided as a single flat-rate annual charge.
