Hi
I (matt) sail in three main places. To date these are:
Shepperton Marina (where my Grandads 1:1 boat is kept)
The Thames (I always take a boat with me on my boat holidays, so far the furthest up my tug has been is Abingdon)
Portishead boat lake (a lovely huge bit of water, although it has its fair share of horrid toy "speed" boats that I usually end up rescuing when they break, I sail there when I stay with the grandparents who live in Weston in Gordano, a small village nearby). Have encountered and almost collided with hovercrafts there, usually I am the only "non-toy" boat sailing when I am there.
I myself live in Chertsey, Surrey
