Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Dockwa

  • The marina absorbs the transaction cost because Dockwa forbids charging boaters more for booking through the platform, so roughly three and a half per cent of dockage revenue comes off the marina margin.
  • Pricing has shifted from purely transactional toward an annual software fee plus transaction costs, which changes the economics for marinas that signed on the original basis.
  • The revenue management and premium capability sits behind an extra monthly subscription of a few hundred dollars, so the useful version of the product is not the entry-level one.
  • Demand is heavily concentrated in North American cruising corridors; a marina elsewhere pays marketplace economics for software-only benefit.
  • A marina that comes to rely on Dockwa for occupancy has handed its customer relationship and its booking channel to a third party, which is a real strategic dependency in a fragmented industry.

StormGlass

  • The free tier allows 10 API requests per day and is not licensed for commercial use
  • Commercial use and any support at all start at the Medium plan, 49 euros a month
  • The Small plan at 19 euros a month has no support and no commercial licence
  • Request allowances are daily rather than monthly, so a burst of traffic cannot borrow against a quiet week

Answered from the vendors’ own pages

Dockwa: What does Dockwa cost a marina?

Around 2.5 per cent card processing plus roughly 1 per cent service fee on bookings taken through the platform, with premium modules such as revenue management sold as an additional monthly subscription near 299 dollars.

StormGlass: Is there a free tier available?

Yes, Stormglass offers a free plan with 10 API requests per day, including all weather parameters, but it is not permitted for commercial use.

Source
Dockwa: Does the boater pay a fee?

No. Dockwa requires that boaters pay the same rate through the app as they would by calling the marina, so the cost sits with the marina.

StormGlass: What does the Medium plan include?

The Medium plan costs 49 EUR per month and includes 5000 daily requests, all weather parameters, and full support for commercial use.

Source
Dockwa: Is it worth it outside the north east and Florida?

Less so. The software works anywhere but the demand side is concentrated, so marinas in thinner markets pay marketplace pricing for management software.

StormGlass: Is annual billing available?

Yes, a 10% discount is available when paying annually on Small, Medium, and Large plans.

Source
Dockwa: Can it handle seasonal contracts as well as transients?
