Hi Gary, still find out..as the place of photo very far fm my location.so delay it maybe :)

Wow..... Fascinating! I wish this was identified! Not a typical ‘ferry’ configuration?

Since she was spotted at Indonesia, I would guess she was an old ferry, serving people as transportation from island to island. Quite common to have boats of such design over there.

The bow is to proud for a farmile no. But I see where you're going

My first thought was an old WWII Fairmile motor launch that's had a bit of surgery done on it. Does seem an odd configuration though.

Looks like something left over from a James Bond movie.
