Design of Netherlands (traditional ?) open motor boat

Has anyone have any information about or seen an open motor boat possibly based on traditional fishing or canal boat used in Netherlands, about 8-9mt loa, 2.8-3.0mt beam, deep draft round bilge and canoe stern with deep gunwales. Looks like a 1900's small ships gig or lifeboat. Probably had a de-mountable rudder with standing coxswain tiller.
I've had a request to build one but all I have seen is a single old photo, would like to get some details if possible to confirm the boat.

 

Do you mean a sloep?

I think you are talking about a 'sloep'. Just google it, and you will find lots of pictures. Here is one (if I can get this attachment to work):

You're a legend EuroCanal, thats the same open boat. Thanks, much appreciated.

Cheers
