Mast Step Re-fit
By Dan Pfeiffer and Graham Bryan
The OEM mast step on the 10M is made of steel. It sits in the bottom of the bilge and is in direct contact with the aluminum mast. Add a little salt water to the bilge and you have a perfect environment for galvanic corrosion where the less noble metal (the aluminum mast) will start giving up material. There are several ways to address this corrosion problem. This article will discuss three of them. The problem is seen in other Pearsons (see “Model Maintenance Crossover” on page 13). The 323 and 365 have the same step. See the 10M website for more photos and details on the repair methods.
