How to Measure Your Boat

A  Maximum  of 64" Tube Center to Center
B  Maximum  of 10'-6" Distance from Bow Tip to Transom Support
Adding Tongue Extension EXT-BB allows Dimension "B" to be:
B  Maximum  of 13'-6" Distance from Bow Tip to Transom Support
SUT-450-I will adjust to fit most smaller models of the above listed boats,
and boats up to a maximum 64" from center of one tube to another.  Example:  boat is 72" wide total with 18" diameter tubes - subtract the width of one tube to determine centerline = 54" which is within  the 64" maximum centerline allowed.
Size Limit on Inflatable Boats -  In order to support the Transom, the boat should be no more than 10'-6"  ( 13'-6"  with Extension EXT-BB)  from the Bow Tip of the boat to the Rear Transom.  Dimension "B"

It is best to physically measure  the boat, however you can compute it approximately by:
EXAMPLE :  Boat is 12' Overall length - the inside distance from the inside front to the transom is listed as 8'-0" - Add the Tube Diameter 18" =  9'-6".  The Rear Transom Bunk  will then position under the transom for support. 

 Maximum Outboard Motor  Weight Limit is 75 lbs
Maximum Total Weight Limit of Boat, Motor & Gear is 450 lb.

See Model UT-850-M for Boats requiring Capacity up to 850 lbs.

         Optional Extra Equipment

SPGAL Spare Tire Galvanized   69.00
STC Spare Tire Carrier   59.00
WNC Winch with Strap & Hook 159.00
TCBS-6 Twin Center Bunk Supports ** 295.00
EXT-BB Tongue Extension to 15'-5" *** 299.00


Optional Twin Center Bunks
    ** Option TCBS is used when you want extra center support because the boat would be transported  with gear loaded, or you have a RIB (rigid inflatable boat)  and you would like additional  center hull support - The Four supplied bunks will adjust to give proper hull support for a RIB and it is not required that you add the center bunks for a RIB, but some users may wish to add them. All Trailers have rear transom supports.  Shown with Transom Support Removed - Transom Support can be left installed with the Twin Center Bunks.


*** EXT-BB Tongue Extension to 15'-5" is a longer section of tongue that replaces one of the pre-packed tongue sections in the SUT-450-I package.  So you will have an extra tongue section left over, which is not returnable for credit.  However, if you ever wish to shorten the trailer, it can be easily adapted with this extra remaining piece.





  Bearing Protection System
  Included on Every Trailer

Sure Lube low pressure bearing lubrication system.  Protects bearings and prevents any seal damage. 
Easy to use. A Zerk Fitting is located under the axle's end cap. Removing the end cap allows you to use a
small grease gun to lubricate the bearings. 
The new grease pushes the old grease out. 



Optionally, this trailers may be delivered to your location fully assembled, depending on your area.  Please contact us for shipping quotes.
