The Restorations of a 1968 Century Coronado 21'
Hull # M6854
Restoration Completed July 2015

The boat as delivered to the shop.

The boat did not look bad, but looks are deceiving.

There were several reason that this boat needed a new bottom. The main one is the original bottom was replaced a number of years ago. (8 to 15 years). The bottom that was installed was two layers of 1/4" plywood with fiberglass coating. The plywood was delaminating due to water getting between the layers over the years. When this happens and the water does not come out rot occurs. Due to either freezing (the leading cause of rot in northern boats). Or fungal groth. Never the less the bottom did not last very long. Another problem with this bottom was the battens were removed which took lateral strength from the bottom. This bottom flexed 2 to three times that of a normal bottom.

The boat upside down waiting for the bottom to be removed.

The bottom being 2 layers of plywood with fiberglass coating needed to come off with a saw.

The bottom removed.
