Filming on a boat?

[Karel B]

Hi guys!

Been a while since I last posted here. Hope everyone is fit n well.

As some of you already know, I work in the film industry in the UK. I subscribe to a BB there where other film folk post questions, and someone has just asked this:

• Hi, I'm planning a shoot which involves shooting (with a cast/crew of about 10 people) at sea on a small yacht. Anyone done this before, and if so, can you give me any pointers as to what problems/issues I will encounter, and any additional safety or insurance issues I should plan for?
  
  Thanks, Paul J

So I thought I'd ask the old sea dogs here (and include a link on the BB) to see if anyone here had any advice to give or relevant experience.

I'm also curious about any other tips / stories (or links) people may have regarding filming on a boat or at sea that go beyond what Paul is asking.

Cheers!
