PLEASE NOTE THE COST IS FOR ALL 4 THEORY MODULES (4 - 4.5HRS TOTAL) and this booking is for all 4 modules but the times of each consecutive module are listed below (no need to book separately)


This course is for confident paddlers with SUP experience on moving water who want to paddle on the Tidal Thames safely and more independently understanding the tides, navigation rules, traffic patterns, risks and hazards of a tidal urban river, and be able to plan their own trips looking at the tides and weather data.

Online course - 4 Theory Modules (approx.4- 4.5 hrs total learning time) in 3 evenings *timings of each module may vary slightly depending on the participants' experience and needs.

  1. Thursday 3rd February 6.30pm - 8.30pm approx. Module 1 RIVER KNOWLEDGE

*Module 5 (£55) Practical 3hr Guided Trip on the Tideway needs to be booked separately once we are allowed to take groups on the water again. Private 1:1 or 1:2 practical session with Paul could be possible on request.

Thames Tideway is a beautiful but very specific urban body of water with a huge tidal range, strong currents, busy traffic and risks associated.

The Thames Skills & Knowledge (TSK) 1 course aims to provide a good knowledge of the main risks for people navigating the Thames in unpowered craft. It has been developed in cooperation with the Port of London Authority (PLA). Content has been agreed with the Assistant Harbourmaster responsible for sport and recreation.

Although mainly aimed at paddleboarders, this training is also relevant to canoeists (excl. SUP specific Modules Modules 2 and 3, although recommended for anyone who would like to broaden their range of paddlesports).

Completion of TSK1 is required by the PLA for anyone wanting to paddleboard downstream of Putney Bridge and above Chelsea Bridge and for night paddling. TSK1 is also a pre-requisite for taking TSK2 allowing paddle boarders down to Tower Bridge in groups. 

TSK1 is aimed at paddlers with some Tideway experience / canoeing on the Tideway but who want to expand their knowledge and paddle alone / in unguided groups (above Putney) or in small unguided groups (Putney – Chelsea Bridge) and who want to paddle in groups at night.

What to bring

You can do it from the comfort of your sofa. A cup of tea or a glass of water is recommended but not obligatory.

No writing materials required - just an open mind. However, if a notepad gives you assurance, feel free to make notes.

1. Cancellations by Active360 

We very rarely need to cancel or postpone sessions due to inclement weather, adverse river conditions or circumstances beyond our control e.g. unexpected river closures, red flag warnings etc. In such situations we will offer an alternative day/time at no extra charge accommodating your requirements as much as possible or a credit note for future booking if you are unable to make immediate alternative plans.  

Refunds will be considered in some circumstances but these are only made on individual basis.  

Weather conditions in the UK are changeable and we are used to operating in various conditions. When the conditions are not favourable we may contact you in advance to see whether you still wish to continue with your booking or you would rather postpone. 

We are not able to accommodate customers’ weather preferences and we have run some of our best and memorable sessions in challenging conditions e.g. rain and/or wind. 

Please share your concerns with us and we will be happy to discuss with you and make any reasonable adjustments to ensure you have an enjoyable experience.
