Frequently Asked QuestionsFrequently Asked Questions
What is hull cleaning and why is it important?
Hull cleaning removes marine growth that increases drag and fuel consumption. Regular cleaning restores speed and protects your boat’s surface.
How often should a boat bottom be cleaned in the Bay Area?
Most boats need monthly cleaning in warmer seasons and every 6–8 weeks in cooler months.
Does marine growth affect fuel efficiency?
Yes. Heavy fouling can increase drag by 10–30%, forcing engines to work harder and burn more fuel.
How do zinc anodes protect a boat?
Zincs prevent galvanic corrosion by sacrificing themselves instead of your prop, shaft, or hull hardware.
When should propellers be polished?
Prop polishing is recommended during regular hull service or when vibration or performance drops are noticed.
Can underwater inspections prevent costly repairs?
Yes. Early detection of corrosion, damage, or fouling prevents expensive long-term issues.
Do I need professional divers for boat bottom cleaning?
Professional divers ensure safe, thorough cleaning without damaging coatings or hardware.
