We've compressed and optimized the complete US Coast Guard's boat manufacturer database of over 16,000 boat builders, and over 30,000 brands to fit on your iOS device, so you can have lightning fast results wherever you are, with NO Internet access needed! No more wondering "Who made that boat?" Important HIN Search features include: • Decoding of US 12 digit and 14/15 digit HINs • Detection of suspicious or possibly altered HINs - an important first step to make sure a boat is not stolen! • Boat manufacturer and build date information. • Print, copy or share your results. • Searching for manufacturers by their company or brand names • No Internet access needed, so you can use this app no matter where you are. • Favorites List, including your own personal notes. • Share/Print/Save results as an Image. • Developed by someone who knows and understands boats. Nearly all boats (including fishing boats, power boats, sail boats, jet skis, kayaks, and canoes) imported or built in the US since 1972 are required to have a HIN by the federal government. The HIN will include when the boat was built, and by who. With the included Manufacturer database, HIN Search can also tell you a little bit about the builder, such as if they are still in business, their address, and sometimes even a website. What this app DOES NOT do: • Retrieve boat model information other than year. This information is NOT encoded universally in the HIN. If the boat manufacturer is still in business, please contact them directly with your HIN. • Tell you if the boat is stolen. We can tell you if the boat HIN looks suspicious and warrants a closer look, but that's it. • Decode boat identification numbers for boat built before 1972. • Retrieve boat's past or current owners or sale information. Please contact your local vehicle registration authority. Please don't leave a negative review with regards to what is clearly stated above! This app only decodes HINs for boats which were built or imported legally in the USA since 1972. Some older (1970s) boat manufacturers "in business" dates may be incorrect. The USCG records are sometimes inaccurate. This is a great tool for both marine professionals and boat shoppers! No limits on number of HINs you can decode, or manufacturers you can look up. No hidden or extra fees. Buy once, use forever. Ad free, and will relieve you of scratching your head wondering, "Who made that boat?"

This app is intended to be used as an aid in locating your position relative to the areas displayed on the map. Mapped areas include private oyster ground leases, oyster ground applications, fixed fishing devices, public clamming grounds, and the blue crab sanctuary. The accuracy of your reported location on the map varies due to many factors, but it is generally expected to locate your position within 50 feet of your actual location (for gps equipped devices). This app will work without a cellular or wireless connection. When your device is connected to a network, the app will download our map data every five days to ensure your maps are relatively current even without a network connection; if your phone does have an active network connection the app will use the most current map data we have posted. As with all Commission GIS data this standard disclaimer applies: this GIS data is not guaranteed to be accurate and complete at any given time. It is the individual's responsibility to adhere to all regulations while harvesting and navigating with the aid of this app. Not all areas such as navigable channels, restricted buffer zones or condemnation zones may appear on the map you are viewing. Although it is expected that the data will be used for regulatory and permitting processes, any user of this data should verify their use of the data with Marine Resources Commission and/or VDH Division of Shellfish Sanitation staff before taking action or otherwise using the data to make decisions, particularly when related to regulatory and permitting processes, or any other legal action. Note that the use of data pins to provide simple feature attribute data can, for some features be difficult to interpret, please use the Web-based map in this app under Online Resources or the VMRC Chesapeake Bay map (https://webapps.mrc.virginia.gov/public/maps/chesapeakebay_map.php) to see more specific data related to the GIS layers presented by this app.

Verdict

The call

HIN Search and VMRC Maps both sit at 4.6 stars, but that hides the real split: 100% of VMRC Maps's written reviews are positive against 41% of HIN Search's. VMRC Maps also leads on price (Free vs $8.99) and update cadence (every 2 months vs every 8 months). HIN Search's advantage is chart position (#190 vs unranked) and ratings volume (73 vs 11). On rating, ads, in-app purchases and device support there is nothing between them.
