Add your boat
Start from a public model, a manual upload, or a manual entry when the catalog is missing your exact hull.

Product tour
Four steps from scattered files to a usable boat record.
02
Capture evidence
Save photos, documents, service entries, parts, and measurements as the boat changes.
03
Find records fast
Search across specs, manuals, service history, parts, photos, and measurements from one place.
04
Share only when useful
Keep the record private, share a vendor-safe view, or publish approved model knowledge.
Connect your AI
Ask your AI about the boat record you built.
Connect ChatGPT or Claude without waiting for an email. Questions stay read-only, and private records stay off until an Owner Pro customer turns them on. Gemini, Grok, and Perplexity are coming soon.

Private deep-data access remains off unless an eligible owner separately enables it.
Read-only
The connector can answer questions, but it cannot change, share, upload, or delete records.
Owner boundaries
One collaborator cannot expose another owner’s private data, and photos stay excluded.
Live public model knowledge
Public pages help you compare what other owners have learned.
Your private record comes first. When you want model-level context, public pages keep approved specs, guides, service patterns, and reviews together.
Open public model pagesPublic model pages
Browse approved specs, galleries, guides, known issues, and model-specific context.
Upgrade guides
Read owner-authored walkthroughs with steps, tools, costs, and lessons learned.
Maintenance intervals
See service timing patterns from similar boats as more owner logs are approved.
Vendor reviews
Find shops and technicians connected to the model families they actually service.
Roadmap signals: On the roadmap - Email digests · Cloneable build templates · Refit cost ranges · Sister-ship meetup map. These stay separate from live capabilities until they ship.
Private by default
HIN, registration, marina location, and account details stay out of public model knowledge.
Built for the dock
The core actions stay practical: add boat, upload manual, log service, save measurement, find record.
Useful when selling or servicing
A clean record helps a mechanic, surveyor, broker, or future owner understand the actual boat.
Start with the boat in front of you.
Add one boat, upload one manual, and make the next service question easier to answer.
