How it works
The goal is a confident go / no-go on a boat before you spend on a survey. You get there by doing the cheap homework first, in one place, with every claim tagged by how much to trust it.
Tell it what matters to you
The Loop's hard limits are fixed: air draft, draft and range. Everything else is yours: diesel or gas, a price ceiling, two heads, a walk-around queen, thrusters. Weight what matters to you and switch off what doesn't.
- ✓ Air draft (lowerable) under, for your route: Chicago · 19'6" ▾
- ✓ Water draft (loaded) under · clears 5'0"
| On | Criterion |
|---|---|
| ✓ | Diesel power |
| ✓ | Price at or under 200000 |
| ✓ | LOA at or under 50 ft |
| On | Criterion | Weight |
|---|---|---|
| ✓ | Two heads | 2 ▾ |
| ✓ | Walk-around queen berth | 2 ▾ |
| ✓ | Fresh water capacity 120 gal | 2 ▾ |
| Washer / dryer | 1 ▾ |
The gates are the Loop's. The weights are yours, and that's what makes the score your score.
You paste the listing
Nothing gets scraped. The parser proposes the fields and you confirm them.
Two answers at once
Does it clear the Loop's hard gates (pass, fail, or needs verifying), and how well does it match what you said you wanted? Mission fit and personal fit, side by side.
| Gate | Status | This boat | Loop limit |
|---|---|---|---|
| Air draft (lowerable) under | VERIFY | — | 19'6" |
| Water draft (loaded) under | PASS | 3'8" | 5'0" |
| LOA at or under | PASS | 41.3 ft | 50 ft |
| Range (at displacement speed) | VERIFY | — | 250 mi |
| Diesel power | ✓ | gate |
| Price at or under $200,000 | ✓ | gate |
| Two heads | ✗ | wt 2 |
| Walk-around queen berth | ✓ | wt 2 |
| Fresh water capacity | ✓ | wt 2 |
That amber row is the point. No professional review publishes a bridge clearance for this model and the listing didn't state one, so the gate says VERIFY instead of a confident green, and the dossier tells you to bring a tape. Below it, the boat has one head and you asked for two. That's a real miss, and it costs the match score.
Then the part a listing won't tell you
The known trouble spots for that exact model, with every claim tagged for how much to trust it: verified fact, listing claim, fleet pattern or open question.
And the brief you hand your surveyor
It carries the model-specific check items, this boat's open questions and what's already verified, so your survey money is spent looking in the right places.
It gets more certain as you go
Every answer you confirm moves a claim from "stated" to "verified", and you watch the number climb.
Not all verification counts the same: a professional survey earns full credit, a measurement or document a little less, an owner's word less again, your own note least. A seller's or listing's claim earns nothing at all.
The longer version
Add a boat
Paste the listing text. We never scrape or fetch listings. It's parsed into structured specs you review, so nothing is saved that you haven't seen. It takes whatever the listing actually states: price, engines, tanks, layout.
Get an instant read
The hard gates (air draft, loaded draft, range) score right away as pass, fail, or needs-verifying. Alongside them you get a model profile: the known traps for that exact model, researched from the owner forums, reviews and boat tests and cited to its sources instead of pulled from one listing. Every item is tagged by confidence, and none of it is a verified Fact until a human confirms it.
Do the homework
Every open question lands on a checklist. Comb the listing first. The photos, the spec sheet and the description often answer them. Then verify what you can yourself; each answer re-scores and drops off the list. Then send the broker or owner only what's left (we draft the note; you send it). No money spent yet, and the read sharpens as the answers come in.
It gets more trusted over time
Owners and buyers confirm and correct the model profiles, so each model converges toward verified truth, and the next shopper of that boat inherits it. Your search feeds the next person's, and theirs feeds yours.
Decide before you survey
Now you know whether this boat is even worth a survey. The survey and sea trial still happen, but only on a finalist that already cleared the homework. The money's spent well instead of wasted on a boat that was never going to fit.
Every claim wears its confidence
You always know how much to trust a line. That's the whole point.
You still need a survey. We just keep you from wasting one on a boat that was never going to fit.
