Decades ago friends with 41’ sailboat out of San Diego, had their boat attacked by whale while at sea. They believed orcas are miss-identifying white hulls as female orca & are attempting to mate.
Friend told me he wanted to invent sonic device that annoyed the males away. Also was experimenting with hull paint colors.
He’s gone now but I imagine others are working on similar solutions.
I loved sailing on September Morn.
