Here’s the link to Whatcom County’s 2015 bid document for the annual drydocking, repair and maintenance of the Whatcom Chief, ferry to Lummi Island. (The pdf file is located on the searchable, public Whatcom Ferry Documents Archive). It includes all the specific required work, including photos of areas needing repair or replacement.
The successful low bidder was Puglia Engineering (multi-state corporation) for $464,289, which was approved by the County Council in June 2015.
This should reinforce, for everyone, the need to get moving on planning for a new ferry. In the meantime, I personally hope that Whatcom County Public Works is/will be working with other counties with ferries to ensure that drydock bids are as reasonable as possible.
