It was a friend's sister's 30th birthday last weekend and a bunch of us hired a couple of boats on the Norfolk Broads for a little celebratory holiday. I figured that since they'd been nice enough to invite me along, I'd do something nice and make a cake in the shape of the boats we were hiring...

This was the initial design after learning that we'd be spending the weekend on a barge...

...except on further digging I found we were staying on something more like this so I had to go back to the drawing board with very little time left to make it.

Here's the basic sponge cake, all jammed-up and ready for the marzipan.

Marzipan layer added.

Iced and decorated.
In the end, the boat was small, cramped and very very warm at night. However the beer, boating and company more than made up for it, including the massive game of water-pistol pirates in small lake off the side of the main river, which the locals really weren't impressed with :-).
I also slightly overestimated the amount of cake for the number of people, so the leftovers were given to the swans that had been following us all holiday, but they weren't impressed either when it sank without a trace. Too much icing, maybe?
