  - Prepare a request about one yacht for the person to review and send themselves on yachtfinder.co. This tool never sends anything: it saves a draft (the yacht, optional dates and up to 5 short questions) and returns one link. Give the person the link and tell them plainly that nothing has been sent: on that page they read and edit the draft, sign in, add their own details, and only their tap on Send sends it, under the usual inquiry limits. Take `yacht` from the `id` of a find_yachts, yachts_near or yacht_facts answer; a name is not searched. Questions are shown as plain text: links, markup and line breaks are removed. Do not put names, email addresses or phone numbers in them. The draft expires after 24 hours.

  - before: Search YachtFinder's catalogue of more than 20,000 yachts by builder, length, asking price, build year, status (for sale, for charter, reported sold, not for sale) and place. Returns up to 25 yachts, longest first by default, each with her status, the broker's asking price, YachtFinder's estimate where her page shows one, and a link to her page on yachtfinder.co. `near` keeps yachts whose AIS position, as the site publishes it, lies within `radius_km` of a named harbor or anchorage; `listed_in` matches the town or country the broker's listing states. A yacht listed by more than one brokerage is one result, as on yachtfinder.co, with the others in also_listed_by.

  - before: List the yachts whose latest AIS position, as yachtfinder.co publishes it, lies within a radius of a named harbor or anchorage (e.g. "Port Hercule", "Antibes", "Off Monaco") or of a latitude and longitude. By default only positions from the last 24 hours. Each yacht comes with the time of her fix, her distance from the place, whether the harbor's page counts her in port, and a link to her page. A yacht whose position the site does not publish is never listed.
