The Speedboat (Husky 19) use a similar trailer that the Batboat but with small difference !

Husky trailers (gold or blue) hitch with hole are only for the Speedboat (Husky 19), the Husky trailers (gold) hitch with pin are only for the Batboat. If you find a Corgi Batmobile 1002 with an Husky trailers hitch with hole, it's not a factory assembly.

Corgi blue trailers (hitch with hole) are only for the Speedboat (Husky 19). If you find an Corgi Batmobile 1002 or E69 with a Corgi blue trailers, it's not a factory assembly.

Corgi silver trailers (hitch with hole) are for the Speedboat (Husky 19), i don't know if you can find with the Batboat.
