A traffic-light notification system for The River Thames conditions.

River Thames Conditions

As the river looks to calm down from the flood use our River Thames Conditions page to help plan the safe movement of your boat. This information is useful for planning your arrival to us for winter boat storage as the water levels are now beginning to drop.

Boat Antifreeze

It is time to prepare to decommission your boat's engine to protect against frost damage during the winter months. Antifreeze, tarpaulin covers, dehumidifiers, and fuel storage treatments are available from stock.

Winter Boat Care - Post-Season Clean

It is a good idea to give your boat a post season clean before it is stored for the winter. Cleaning off dirt, grime and even algae that has built up from a season afloat will make it easier to clean in the Spring. Taking time to clean the bilges, engine bays and accessories such as fenders and ropes prolong their life span.
