  This paper is a continuation of earlier work on the construction of contact
forms on seaweed algebras. In the prequel to this paper, we show that every
index-one seaweed subalgebra of $A_{n-1}=\mathfrak{sl}(n)$ is contact by
identifying contact forms that arise from Dougherty's framework. We extend this
result to include index-one seaweed subalgebras of $C_{n}=\mathfrak{sp}(2n)$.
Our methods are graph-theoretic and combinatorial.
