It's one extra level of indirection. In the housing market, landlords do sometimes pay for upgrades to their rental properties, but they are less likely to do so than owner-occupiers.

Additionally if the ship owner was also the operator, they could benefit from some vertical integration, training their crew on the new technology.

If the effect of the kites on prices becomes large enough or the technology becomes standard, expect widespread adoption, but it's a reasonable claim that the existing market structure slows rollout when it's only marginally profitable.

Is that a fair companrison? An owner occupier will often over capitalise because they desire something or have a lifestyle benifit beyond money. A rental owner wil look at dollars in/out. With the ships, its all coming down to a spreadsheet of cost vs benifit for both owner and hirer.
