Divide the verticle weight on each strap by the cosine of the angle on the strap to figure out the tension in the strap and stress on the lifing eye.
exp: at a 30 degree angle, if a strap is supporting 3000lbs of vertice weight, the strap will have 3464 lbs of tension.
Then add a huge factor of safety and take good care of them.

Assuming Jim(Donzilla) has the same straps I do, mine are rated @ 3000 lb per strap(x3) which handles my 4700 lb boat to perfection, Brad would just have to get extensions to get the bow approx 1 ft higher than level which allows the water to run out and makes it easy to place on trailer. Jim's are perfect for the Saber providing they are in good condition.
