Yarrow's three dry docks and Type 26 capacity

Can all three Yarrow dry docks take a Type 26 frigate?

Yes; even the shortest appears long enough, so three hulls could theoretically occupy the docks simultaneously.

All three Yarrow dry docks appear long enough to take a Type 26 frigate. The length check gives 525 feet for the shortest dock and 491 feet 10 inches for the ship, leaving more than thirty feet of clearance. On that basis, three ships could occupy the docks at once without a later hull waiting for HMS Glasgow to leave. A possible fourth dock is mentioned only as an option requiring further work.
