TSK1 Online Theory - 4modules 3 evenings

TSK 1 Theory part £65

This course is for paddlers with paddleboarding / 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. It's run by our sister company, Active360, who have 8yrs + paddleboarding experience on the Tideway.

Online course - 4 Theory Modules (approx.4.5-5hrs total learning time) in 3 evenings *timings of each module may vary slightly depending on the participants' experience and needs.

  1. Sunday 21st June 7pm - 9pm Module 1
  2. Monday 22nd June 7pm - 8.30pm Module 2 & Module 3 combined
  3. Wednesday 24th June 7pm - 8.30pm Module 4

*Module 5 (£45) Practical 3hr Guided Trip on Thames can be booked separately.

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.
