Carfax for Boats
Carfax for Boats is still in active development. It is a studio-built project, not a client engagement, and there is no release date yet.
Carfax for Boats
Project overview
Introduction
Carfax for Boats is an Arranto-built project, not a client engagement. It asks a simple question: when a car changes hands, a Carfax report can show its history — what happens when a boat changes hands? The project is under active development, with a public repository showing ongoing commits.
The Problem
A boat's maintenance history typically lives in scattered paper receipts, a seller's verbal account, or nowhere at all. None of it reliably follows the boat when it's sold, which leaves buyers guessing about engine hours, service intervals, and past repairs, and leaves sellers with no easy way to document the upkeep they actually did.
The Technology
The project is built as a Next.js Progressive Web App, so it can be used from a phone at the dock without an app-store install. It uses Claude's vision API to read photos of physical source material — an engine plate, a receipt, an hour meter — rather than requiring manual data entry.
Key Features
- Photo-Based Input: Capture an engine plate, a receipt, or an hour meter reading directly from the PWA's camera.
- AI-Assisted Extraction: Claude's vision API reads the photographed details instead of a person typing them in by hand.
- Structured Records: Extracted information is organized into a maintenance record tied to the boat.
- Designed to Transfer: Records are built to move with the boat to a new owner rather than staying locked to one account.
Target Use Cases
The project targets boat owners who want a running record of their own maintenance, sellers who want to document a boat's condition before listing it, and buyers who would rather see a structured history than take a seller's word for it.
Challenges
Reading real-world engine plates, faded receipts, and mechanical hour meters is harder than reading a clean digital document — stampings wear down, paper fades, lighting on a boat varies, and handwriting isn't consistent. Vision-based extraction in a marine environment has to work with source material that's often worn, glare-affected, or handwritten rather than printed.
- Is Carfax for Boats live or available to use right now?
- No. It's under active development as an internal Arranto project, with no public release yet.
- Is this being built for a specific client or marina?
- No. This is Arranto's own build, not a client engagement, and there are no confirmed marina or brokerage partnerships at this stage.
- What's the technology behind it?
- It's a Next.js Progressive Web App that uses Claude's vision API to read photos of engine plates, receipts, and hour meters and turn them into structured maintenance records.
- How accurate is the AI at reading things like engine plates or handwritten receipts?
- That hasn't been measured or published. The project uses Claude's vision API for this kind of extraction, but no accuracy figures exist yet for this build.
- Will maintenance records really transfer to a new owner when a boat is sold?
- That's the design goal — records are meant to move with the boat rather than stay tied to one account — but that transfer flow hasn't been used in a real sale yet, since the project is still in development.
