They are called "lofting ducks" or "spline weights and you can find some
fancy ones he http://www.boatsofwood.com/ Edson also has some really fine
cast bronze ones for about $35 each. For a more practical version
http://www.splineweights.com/checkout.htm has them for $12 to $18.

for small wooden boats ? Thanks - Dan
