Train to stand the watch. Practice COLREGS the way the board tests them—timed drills, typed-recall, and instant rule references. Fix your weak spots before exam day.
SeaSmart helps mariners master the Rules of the Road (COLREGS) and walk into their exam ready.
Whether you're a deck cadet preparing for a Coast Guard board exam, a watch officer brushing up, or a recreational boater who wants to truly understand the rules, SeaSmart turns dense regulation into confident recall.
TRAIN THE WAY YOU'LL BE TESTED
Board Mode mirrors the real exam: fixed 25-question drills, a 60-second timer per question, no hints, and feedback withheld until the end—just like the board. Mixed multiple-choice and typed-recall questions force you to actually know the rule, not just recognize it.
PRACTICE ON YOUR TERMS
Quiz Mode lets you choose your topics and set session length from 5 to 50 questions. Turn on "Focus on weak areas" and SeaSmart prioritizes the questions you've missed before, so every session sharpens the gaps that matter most.
THE FULL COLREGS, ALWAYS IN YOUR POCKET
Read all 38 rules verbatim, with both International and Inland variations side by side. Full-text search finds any rule or term in seconds, and built-in mnemonics make the tricky rules stick.
SEE YOUR PROGRESS
