Workboats too expensive?

[Matutin]

Comparing Workboats to workers, both cost almost the same, although the worker is far more versatile and universally better.
Shouldn't a boat therfore be cheaper?

 

[Blue Ghost]

The workboat is fine. It costs 40 production, which is less than a monument or shrine, and gives comparable yields, in addition to connecting a resource.

A worker costs twice as much as a workboat. Workers can build more improvements, but they're a longer-term investment with diminishing returns, so they're not really comparable.
