Here is the cake I made for my husbands birthday on Monday. Lemon with Lemon Curd Filling. The sail is actually paper (I used an image from the Silhouette machine-worked great because the holes weren't too big). I think it turned out pretty cute especially since there was a minor catastorphe and his poker friends dropped a cutting board on the backside that I had to "repair", at least it was on the back right and the boat covered any problems.
You can kind of see the damage to the back in this picture (the cake is slightly lower in the back) thank god I had a little leftover frosting to fix it.
