Once again I was away from the BIANKA for an extended period of time. One month or so. I wanted to avoid the marine growth on the prop the boat experienced earlier this summer as you can see below:
So this time I decided to do an experiment of something I had heard about from other sailors. Before I left the boat I covered the prop with a plastic bag. One of those that you get when you buy something in supermarkets etc... I tied it around the prop and came back a month later and it looked like this:
I dove under the boat just using my snorkel and quickly removed the bag from the prop:
I must say it worked pretty good in keeping the prop clean of the major marine growth and only had a barnacle or two on the blades:
So if you are going to away for an extended time covering the prop with a plastic bag does work pretty good in keeping marine growth off the prop.
