## Idea

Boston tall-ship identifier
Helps families identify tall ships in Boston Harbor from visible mast, sail, and hull features, then collect digital port stamps.

## Product concept

When parents take their children to Boston Harbor to see tall ships on a weekend, they open the map and see a clickable mast silhouette floating above each ship in the camera view. Users do not need to recognize the ship name first. They choose the number of masts, sail shape, and hull color they can see, which narrows the result to several candidate ships. After confirmation, the page shows a one-minute illustrated explanation of why the ship looks that way and a viewing point it may pass next. Children can collect digital port stamps for ships they identify and generate a Boston fleet poster after completing the set. It serves the few minutes when a ship is right in front of you but you cannot name it, rather than being another static event schedule.

## Why now (backed by facts)

Sail Boston 2026 will bring an international fleet of tall ships and naval vessels to Boston Harbor from July 11 to 16, 2026. The official participating-ship and berthing information has also been published. A trend snapshot shows about 10,000+ searches for “tall ships boston” in the past week, with growth of about 75%. Many visitors are looking for ship and viewing information at the same time, making an on-site identification entry point for ships people can see but cannot name worth building now.

## Direction (model inference, not independently verified)

Target user: Parents visiting Boston Harbor with children for a parade, berthed ships, or fireworks. It also suits ordinary visitors without nautical knowledge who only have visual clues.

Minimal entry point: Build the first version as an install-free mobile web page. Enter only the Sail Boston official participating ships and their photos, mast counts, rigging, and hull colors. Users select three visual features manually to get candidate ships, berths, and a one-minute explainer.

The strongest case against: The strongest case against this is that MarineTraffic already offers camera-based ship identification, while the official directory is enough for visitors willing to look up ships one by one. The family explainers and stamp-collecting experience may not be enough to make users open another standalone product.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Create search-indexable “how to identify this ship” pages for each participating vessel. Distribute directly opening ship-identification links or QR codes in Boston family activities, harbor-viewing communities, and photography groups, where people are already looking for ships and viewing spots.

## Competitors & gaps (model inference)

- Sail Boston 2026 Official Ship Directory and Interactive Harbor Map: The official site provides a participating-ship directory, ship types, berths, parade routes, and viewing locations. Its identification entry point is still a list and map. The gap is letting families who do not know ship names filter backward from visible features such as mast count, sail shape, and hull color.
- MarineTraffic: MarineTraffic can already identify nearby ships through the camera using AR and AIS locations. Its core is real-time shipping data and professional vessel information. The gap is a family-friendly experience with visual guidance, short explainers, and event-specific collecting, including situations where AIS data is missing or the camera is hard to aim on site.

## How it makes money (model inference)

Charge families a one-time event pass for access to the complete fleet guide, port stamps, and a downloadable fleet poster.

## Trend background

Theme: Boston tall-ship events
Trigger query (original English): tall ships boston
Approx. search volume: 10000+ (approximate)
Approx. increase: +75% (approximate)

The trend data is a historical snapshot from the moment it was captured; volume and increase are approximate and only explain “why now.” Do not write them into product copy as precise market numbers.

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
