HulloShips is the Zillow of ships: a place to search any vessel, see what it's worth, browse real listings, and explore the entire world of boats and shipping as clean, searchable data. We're building the open reference layer for the water — the numbers and records that used to live only with brokers, surveyors, and harbor offices.
If it floats, we want it findable.
For generations, the simplest questions about a boat — what is it worth, who built it, where can I keep it, who's selling one — had no easy answer. The information existed, but it was scattered, gated, and analog. HulloShips gathers it into one searchable place and gives it the interface people already understand from looking up a house.
You can value a vessel with HulloValue, browse genuine listings, and roam an unusually deep set of reference databases — marinas and harbors, shipyards and yacht builders, brokers and dealers, models and superyachts, and more. Map-based databases draw on real open geographic data; reference databases are researched from public sources and shown with their provenance. The goal is the same throughout: turn the maritime world into data you can search, sort, and trust.
Look up any vessel — make, model, or name — the way you'd look up an address.
HulloValue estimates a vessel's worth from comparable sales and model-specific depreciation.
Real listings of boats and ships for sale, alongside the brokers and dealers behind them.
Marinas, harbors, shipyards, builders, and more — the maritime world as a connected dataset.
Real estate got its data layer — instant valuations, open listings, market history anyone can read — and it changed how millions of people buy and sell. The water never did. Boat buyers still negotiate half-blind, sellers still guess at price, and the records that would settle it stay locked away. HulloShips exists to close that gap: an honest, public reference for vessels and the maritime world around them.
The approach is the WholeTech recipe pointed at the sea — curate the experience, pioneer a niche, own the asset, and compound the value over time. We'd rather build one deep, genuinely useful resource than a shallow directory. Every database is meant to stand on its own and to connect to the others, so a question that starts at a single hull can end at a marina, a builder, a comparable sale, or a fair price.
HulloShips is a venture of WholeVoyage, the travel-and-sea arm of the broader WholeTech network — a family of focused, data-first sites, each one going deep on a single niche. Sharing a design language, an editorial standard, and a build philosophy across the network lets a venture like HulloShips launch with real depth instead of a thin placeholder. The work here is produced by the HulloShips team to the same standard as the rest of the network.
HulloShips carries forward a thread of great American collecting — the conviction that the finest vessels are worth documenting, understanding, and stewarding, not merely owning. That spirit, drawn from one of the most significant collections and naming legacies in the country, is why we treat boats and ships as objects worth a serious public record. We tell that story, and how it shapes what we build, on the Barney page.
