Yes thunder.....I first build a box..then set the model within and set the angles...then I used spray foam and filled the entire box.....noting that there is 30% expansion when cured. I then cut the waves in after I had removed the model(I used plastic wrap as a separator on the hull. I then removed the plastic and then masked off the hull where the water would come in contact. I replaced the model into the prepared foam and then trawled Dental stone over the foam being careful to create realistic wave crests and to prevent spatula marks from being left. I made sure that the plaster did not go too high on the hull to lock the hull in. Once dried, I removed the model and then painted the waves using acrylic paints. Start from the top of the wave(Lightest to darkest)...then finalized with break water and foam.
To finish off I added apple wood to the base. I have more sanding and staining to do on the wood and a light coat of satin finish. A name plate will be fashioned later as well.
Foam core for this size of a sea is a must...it keeps weight down and prevents cracks.
I think it is getting there and I am well pleased with the final result.
Thanks for looking and commenting.
