Do I need to know how to navigate without GPS?

Yes. GPS is wonderful, but batteries fail, electronics malfunction, and signals are sometimes lost. Every boater should understand compass navigation and basic chart reading.

What's the difference between true north and magnetic north?

True north is the geographic north pole. Magnetic north is where compasses point, and the difference (magnetic declination) varies by location.

What do different colored buoys mean?

Red buoys mark the right (starboard) side of channels when entering from seaward. Green buoys mark the left (port) side. Remember 'Red Right Returning.'

Can I use regular maps instead of nautical charts?

No. Nautical charts show depth information, buoys, and hazards critical for safe boating. Regular maps don't provide this data.
