Hi Everyone,
This is actually the first time I am posting my own thread to the site, so hope this works.
After reading many experiences of folks using cold galvanizing spray to prevent barnacles on the shaft and props, I decided to give it a whirl this past season. Boat is located on the south shore of Long Island, NY in East Rockaway. Splashed late April and pulled out for winter storage 3rd week of September.
I sanded smooth the shafts and props prior to spraying the 93percent cold galvanizing paint I purchased from Home Depot. This is essentially the same product as the Petit that can be purchased for much more money at marine stores.
The boat was kept at my yacht club on a face dock, with the port side facing west (lots of sunlight) and the starboard side against the face dock (essentially in shade), from April until mid August when it was moved to an inside slip in the marina.
Being on the face dock made it difficult to run the boat due to prevailing winds causing problems docking without people around to help. So not much boat movement.
The attached pictures (hope this works) tell the story. The port side (sunny side) had unbelievable barnacle growth on shafts, yet not on props. Also, on large zinc grounding plate (never experienced this on any boat I've owned). The starboard side (in the shade) had almost no growth on the prop and shaft.
The struts, well that's another story
So for next year I will use the spray galvanizing again (lots of scraping of barnacle to do) as the boat will be in a regular slip , essentially in shade on both sides.
