: Hi, I'm looking for a set of ships curves and a set of spline weights new or
: used can anyone help me

Try the Woodenboat forums... http://media4.hypernet.com/~WOODENBOAT/wb.htm

You might even pick up a copy of WB magazine. There may be some ads in the back for such items. There was an article a while back, I don't recall the issue, that showed how to make your own spline weights.... very cool.....shaped like whales, methinks (can't remember for sure...the mind ain't what she used to be!). I'll have to dig up the article and let you know what issue it was. There is a search function at the website. You may be able to find it through that. I don't know about the ship's curves. If you just need battens for lofting, you could make those too. The guys at WB will be able to help.
That bunch has a vast collective knowledge of boatbuilding in wood.
What are you building/designing?

Good luck,
garland
