In-depth boat reviews, marine electronics guides, and seamanship tutorials — written by USCG-licensed captains and naval architects. No paid placements. No fluff.
Every review is based on 4+ hours of on-water sea trials. We accept zero manufacturer-loaned boats — all tests are funded by BoatGuider.
Our captains hold USCG Master 100-Ton licenses. Our naval architect has a PhD from MIT. Credentials you can verify.
No listicles. No "top 10" filler. Every guide answers a real question a boater would ask — with specific numbers and recommendations.
