What early Swedish landing craft reveal

What is the significance of Swedish archipelago landing craft built for cavalry?

They show that specialized landing craft are usually shaped by difficult cargo such as horses or tanks, not by infantry alone.

The Swedish archipelago fleet used dedicated, oared landing craft with ramps for cavalry. The example makes a wider design point: infantry can be put ashore in many ways, but horses, tanks, and other heavy equipment impose the decisive requirements. Interwar British uncertainty over growing tank dimensions discouraged large production commitments. A small experimental and industrial base was kept so the Navy retained the ability to develop suitable craft.
