Racing Hydroplanes - Urgent help needed! - Can you telll me more about this boat?

[markbyas]

Hi everyone!

I've been asked to make a model of a hydroplane (OC 0.500 class, I think) as a gift for an Ex-world-champion of 1969,70,72. It's very urgent. It is also a supprise, so asking the guy for infomation is a no no. I have only the Red boat pictured below to go on (him), sent by his familiy. And The other picture is of his late brother racing.

When I asked on boatdesign.net they recmended I post on here.

I know nothing about hydroplanes, and despite my best efforts cannot find the level of detail I'm after

I would like to make the model as accurate, and detailed as possible, to do so I need plans; ideally, but pictures/any more infomation on the craft would be great too.

I really hope someone can help?!

Many thanks indeed,
Mark
