The Baldt Stockless Anchor was patented by Frederick Baldt in 1896. Baldt anchor is one of typical stockless anchors. Its structure is similar to JIS Hall anchor, Spek anchor, US Navy anchor, etc. Especially for US Navy anchor, Baldt looks like it very much. Their difference is in dimension and other small variation. We have documents for boat anchors and we can share all of them to you.
