Peter,

What do you need to do with your offsets? Are you looking for something that can do hydrostatic calculations, or something that'll turn your offsets into a surface model, or just something that'll give you a nicely formatted table?

The easiest way I am aware of would be then to type the offsets in a excel sheet and import them into Freeship or Delftship.

The Freeship tutorial whcihc comes with the freeware, handles the "howto".

(I assume you have freeship)

Regards
Richard

So here's the wire frame, ends still don't quite make sense....funky sections aft around the prop opening....trying to reconcile the sections and the profile doesn't seem to quite work.....

This is with stations and waterlines at 500mm spacing...
