There are some metal rails under the water on the right hand side, there is no where to tie your boat up so it's a double handed job until you get to know what you can and cant do.
There is no toilet in the car park so stop at the services on the way.
The trailers are locked up on the top of the slip so take a lock and a wheel clamp.
Car parking money.
There is a drop off at the bottom of the slip at low water, ask AJ
Don't forget its a river and it can flow well so don't stand in the water on the port side of your boat when launching or you could get pinned between your boat and the under water rails
Ask Trevor G when he is next going out as he will help you like he did me for the first few times
If not then come round to Calshot and we can help if we are around
