Both Ulven Forging and Skookum have a strong relationship with the maritime industry. Ulven Forging produces many items to the customer's design/specifications including ocean towing fittings (tow shackles), shipping container attachments (twistlocks), anti-corrosion components, water-tight door parts, and mine sweeper deck hardware. The Skookum catalog has a variety of blocks, fairleads, and sheaves for use on marine vessels – and they have the ability to adopt these items to the customer's specifications if you don't see exactly what you are looking for.
