We've taken our Centurion Avalanche to Topside for the last 4 years, for repairs, storage and recently a new sound system. Bill & Jim are great to deal with, give impartial advice about the work required and always look to try to save you money. We wouldn't take our boat anywhere else

We have taken our boat to Topside for 8 years and have had excellent service and turn around time. We had them install a tower on our boat and extremely happy with the quality of tower and and installation.

Service to Northern California Wake/Ski Boat Owners for twenty years. We claim to be the best...let us prove it to you. (Bill Topside Marine Service Manager)
