Not Nationally or Internationally !! you could ask Adam Younger what happened with getting it Homologated and he should be able to get the process rolling again.

Would be good to have the Tohatsu 115 as an option - might even use one myself. Will try and check up on the situation.

According to RYA
Tohatsu no longer want to pursue the Homologation might be worth checking with Gordon Sutherland.

Maybe the model is not part of their future plans - will try to find out.
Was also hoping that Selva might homologate their 115 - but don't think that is happening.
Will do some investigating.
