Register every boat against one set of published rules before a fixed date. Publish the rules early, collect the state registration, the insurance declaration page and the fee through one channel, issue a numbered sticker only when everything is in, and give whoever patrols a way to look a number up.
Ask for the page of the member’s boat policy that shows the boat, the liability limit, the policy dates and the association named the way your rules require: usually the declarations page, or an endorsement or certificate from their agent. Check those four things on every document, and record the end date so you can ask for the renewal before it lapses.
Keep one list in date order that members can see, and write down how slip assignment works: who gets the next slip, how they’re told, how long they have to answer, what happens if they pass, and how boats are matched to slip size. Apply the policy to everyone and log every offer.
