TowPro, The Advanced Tender Tow System, enables captains to prevent losses, reduce insurance claims, and continuously monitor.

Benefits of TowPro to insurers and captains

  • Captains benefit immediately from the reduced risk of tender loss, avoiding financial impact for the owner, disappointment for guests, and disruption for the captain.
  • Insurers benefit from reduced level of tender towing risk, allowing them to respond to pressure to reduce restrictions.
  • Reduced restrictions allow captains operational flexibility, which is a direct benefit to them too.

Leading insurers offer improved towing conditions for yachts with TowPro installed as it is the ‘Advanced Tow Protection’:

  • Reducing deductibles for all tender towing.
  • Removing exclusions on towing by night, and/or reducing the higher night-time deductibles.
  • Removing exclusions on excessive miles of towing

These are receiving an enthusiastic response from captains and yacht owners.

TowPro Warning Tender Adrift

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”.

Key Features

‘Eyes in the boat’

TowPro - TSM Systems
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
  • immediate audible and visual alerts if any of these safety indicators exceed pre-set thresholds, giving the crew immediate early warning of potential problems which they need to investigate, and which they can continue to monitor as they take precautionary actions.

‘Bridge alerts’

TowPro - TSM Systems
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 - TSM Systems
TowPro provides comprehensive protection – automatically

TowPro continuously monitors the tow length. If the

tow fails, TowPro automatically activates:

  • Sends immediate alert to the bridge via VHF
  • 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.

Why wait?

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.
