Rooster tail on sub - Page 2

Well answering my own question.
The submerged draft is the draft when surfaced for purposes of painting the sub on the water. Yeah, surfaced. Changed it to match what I have as surfaced depth and the sub is way too tall on the water now.

So the next question, if submerged is how it rides on the surface then what is the surface draught for?

Notice the way it is spelt though? Perhaps it's like the header on a draft of lager?...

Just to close out this thread ... The rooster tail effect was significantly reduced once I got the boat to sit deeper at surface cruising depth.
Its more of a splash than a jetski rooster tail now.

The only time I really see it spray up is in the troughs during rough seas.
