Spring Launch Preparation

Posted by SkiSafe         0

Boat preparation is vital prior to the start of boating season. Follow our pre-launch guidelines to help maintain the various systems on your watercraft ahead of season.  



Take advantage of the off-season days with these informative preparation steps.  

  • Enroll in a boating safety course if you haven’t taken one already. Not only will this help you save on your boat insurance, but the course is filled with worthwhile advice for safe navigation of the craft. Find a class from a qualified organization, sponsored by either the US Coast Guard, the US Power Squadron, or offered through your state’s boating authority.
  • Read through your watercraft’s manual and the recommended maintenance guidelines put forth by the manufacturer.  
  • Do a walk-through of your boat. Refresh your memory on its systems, components, features, equipment, and safety precautions.  



Watercraft Display and Documentation 

Check that all required documentation is current and aboard your vessel prior to the start of boating season. Recreational watercraft should have a state-issued Certificate of Number displayed on the front of the vessel and all federal registration documents readily available.  

If the vessel is owned by a U.S. citizen and measures at least five net tons, it is required to carry a Coast Guard Certificate of Documentation. In addition, if the watercraft is insured, keep all insurance cards and documents aboard the craft.  

Safety Equipment 

It is vital to check that all safety equipment on the watercraft is properly working and up-to-date. Here are the minimum regulations from U.S. Coast Guard. 

  • Personal Flotation Devices: All flotation devices aboard the vessel must be Coast Guard approved. Watercraft less than 16’ must have one Type I, II, III, or V per person. Watercraft bigger than 16’ must have one Type I, II, III, or V per person and one Type IV throw-able device.
  • Fire Extinguishers: Boats less than 26' must have one B-I fire extinguisher. 26'-40' boats must have two B-I extinguishers or one B-II extinguisher and boats40'-65' must have three B-I extinguishers or one B-II and one B-I extinguisher.  
  • Visual Distress Signals: Watercraft less than 16’ must have night signals when operating between sunset and sunrise. Watercraft longer than 16’ must have a minimum of three day-use and three night-use pyrotechnic devices.  
  • Sound Producing Devices: Boats with a length less than 39.4’ must have a horn, whistle, or other device capable of producing sound. Boats larger than 40’ must also have one bell able to produce a 4 second blast for half a mile. 
  • Backfire Flame Arrestors: Gas-powered watercraft of all sizes must have one Coast Guard approved device on each carburetor.  
  • Ventilation: All size watercraft must have one Coast Guard approved powered system.  
  • Pollution Regulations: All boats must follow the “honor system” when it comes to polluting. Boats larger than 26’ must have a 5’’ X 8’’ oil discharge placard and a 4’’ X 9’’ MARPOL trash placard. Watercraft over 39.4’’ must have a waste management plan in addition.
  •  Marine Sanitation Devices: Any toilet installed on a boat under 65’ must be a CG-certified Type I, II, or III marine sanitation device. Vessels over 65’ can only have Type II or III devices.  
  • Navigation Devices: All boaters should be familiar with the recommended rules, but vessels 39.4’ and over are required to have a current copy of the USDOT USCG International – Inland Navigation Rules aboard. 

Electrical Systems

  • Examine all electrical connections on the watercraft and check that they function correctly. 
  • Charge or reinstall all batteries as needed.  
  • Clean and tighten all connections, especially terminals of battery cables. 
  • Coat battery terminals with insulating grease or with a protective battery terminal spray.  

Engine and Fuel System

Take the time to care for your boat trailer to prevent corrosion and breakage.  

  • Rinse the trailer before the start of season and with each use. 
  • Check for rust spots and remove them with a wire brush and a galvanizing component as needed.
  • Grease the trailer’s wheel bearings and replace them when necessary.   
  • Inspect the remaining parts of the trailer, including the bunk, brakes, lights, tires, and bow straps.
