Trailer

Only thing I dislike about the kayak on a trailer is the short wheelbase backing and parking can be a pita sometimes.  I thought having a trailer would replace my need for wheels ... don't make that mistake too 

There's a wheel bearing maintenance enhancement to not launching from the trailer too.  Keeping the trailer wheels out of the water is a GOOD thing.

There are a couple reasons for driving slower with a trailer.  #1 being safety - takes longer (generally) to stop that load.  #2 being wheel speed - this is especially true of small trailers like those we use.  The wheels are normally 8" or 12".  8" traveling at 55mph are turning much faster than a 12" at the same speed thus greater heat to the bearings, rubber, etc.  Trailers with 13"/15" can normally travel faster because the bearings are turning far slower/cooler/etc.  I had a chart at one time but can't find it right now to compare RPM of various wheel sizes.  Wheel hub failures at highway speeds are no joke!  I've had tires blow but luckily no hub failures yet.  I do know of someone recently who DID have a hub failure towing a 24' pontoon boat locally and the tire/wheel/hub came free at highway speeds and went thru the windshield of a car behind her ... nearly killed the other driver.

As I served as the Maintenance Officer in Iraq I can attest wheel bearing maintenance is often overlooked. Our Humvees would come off the road and the GAA (General Automotive/Artillery Grease) would flow like water.  I did some wrangling and found some red synthetic wheel bearing grease that was rated to 500F degrees (GAA was rated at that time to around 250 F degrees ).  Huge difference, we still had to repack after every mission, as the sand would get into everything. But the complete failure was greatly diminished.  If you have 8" wheels consider upgrading to 10" or 12" reduces the rpms and wear/heat on the bearings.

Proper hub maintenance is KEY along with routine maintenance to your trailer components.  Don't forget the safety chains either
