BDSx00 will protect the bulk of your boat…
However, on a sailboat it will not protect your spreaders and the very top of your mast.
We recommend you install ‘bird spikes’, on your spreaders and the top of your mast. Commercial bird spikes can be purchased from many sources including most boating supply vendors.
A ‘home remedy’ alternative that works is to install some plastic tie wraps on the spreaders with the long end pointing up and the end cut off at a sharp angle.
Another option is to tie some mono-filament line from your mast out to the tip of the spreader.
