Chris-thanks for the drawing. I think I'll stick with the whale just now and make one that looks more like an angler fish later, maybe use it as some sort of vehicle landing craft. I find myself getting frustrated as it is without scraping this try and starting again.
Jim-I took your advice and lowered the back bit a wee bit. I also added the tail section. I've still got to finish the tail, but I thought I'd let you all see it before I go any further.....



With the door, I'm going to keep with the size, but I'll make some hydraulics to lift it up over the bow using plastic pipe as pistons.
