@Chris - Well done Sir, that is a beautiful paint and weathering job!

@Andy - You must be very pleased with the way the cockpit has turned out - that's the way you do it!

Moving swiftly on then - I'm calling this one done! Before we get to the finished pics, I'll explain how the base came together.
I have used a cheap photo frame, which I removed the glass and the stand from. I painted a sea pattern onto the chipboard base, in Citadel acrylics - dark (regal) blue, dark (caliban) green, some grey patches mixed in, and then a few grey/turquoise highlight streaks. Once dry, I sealed the base with an acrylic gloss coat. Onto this I put the first layer of Vallejo Water Effects (Pacific Blue).

As you can see, it goes on very blue, but as it dries it becomes translucent, as well as shrinking slightly. As it takes 24 hours to fully dry, it took a full week to build up the waves.
The final application to the crests of the waves was stippled on with a silicon baking brush, to give a foamy texture when it had dried, suitable for drybrushing.

Finally, the whole base received a very dry dry brush of white, followed by a little Vallejo foam/snow over the wake, and where the float skims the water. I found this stuff to be too white, so when it was dry, i blended it back to more of the sea colour with a Citadel wash - Asurmen Blue.
Et Voila!

This project was a lot of fun, with a couple of new techniques tried out. Cheers Everybody!
