Science Teacher and University Lecturer teaching A Level Physics, Biology and Chemistry, but spent much of my teaching in A Level Maths and Computing. Now a Private Teacher. Hobbies Sailing on the River Thames, and making videos and photography.
Sharing the Thames with Rowers, Sailing isn’t a solo act — we share the river with determined rowers who can't see behind them and don’t always know where we're going either. https://pmrsailing.blogspot.com/2025/11/adventure-with-rowers-sharing-thames.html

Want more speed or control?
Check your outhaul.
Tight = flat = fast in wind.
Loose = full = power in light breeze.

We explain how this simple control can reshape your mainsail and your race.

No wind.
No speed.
Just... drifting.
We’ve all had those days. Here's how to make the most of light-air sailing — and maybe even move forward.

Rudder fall off? No problem.
You can still steer a sailboat — using just the sails and your body weight.
We explain how to luff up, bear away, and even tack without touching the tiller.
