Can't exactly help you there, but what I did to make some stickers with the type of boat I own (Hallett if curious), was to take a picture of the emblem on my boat. I then went to the print shop and gave them my jpeg. I told them the dimensions I wanted to the end result and they made them just like I wanted. In addition, I want to put the info on my trailer. So they made me stickers for that also. The sticker lettering was the same font. In my case I had Hallet Vector 21.
So, take a pic of the Alpine logo and go to your nearest shop.
