A number of stackable weights can be bundled together and secured with a lashing to form a modular sinker of a desired weight. Each stackable weight has an elongated bar bounded by four side surfaces and having a fixed eye. A link member is movably attached to the fixed eye and terminates in a coupling eye. The link member provides a degree of motion between the coupling eye and the fixed eye of the bar, allowing the coupling eyes of multiple stackable weights to be connected together to a single fastener while the bars are positioned together in a side-by-side relationship. When so connected, the link members form a pyramid-shaped coupling structure that will reduce the likelihood of snagging the resulting modular sinker. The bars preferably have textured side surfaces to frictionally engage each other to maintain the bars parallel and to retain an elastic band that provides the lashing.
