When choosing a suitable Tube Rope please consider the value of what and who you are towing behind your boat and invest in the proper tow rope for the style of Tube. We have a range of appropriate ropes: One man Inflatable Towable Ropes, or Two man Inflatable Towable Ropes, or Multi-rider Inflatable Towable Ropes.
The governing body of the water sports industry (W.S.I.A.) has taken this matter seriously and has done extensive testing and standardisation to come up with recommended tensile strengths.
Recommended Tensile Strengths.
1-2 person - up to 2,375 lb breaking strength
3 person or less - 3,350 lb. break strength
4 person or less - 4,100 lb. break strength
6 person or less - 6,000 lb. break strength
Don't buy just any rope.
Many consumers simply go to their local DIY store to pick up 60 feet of polypropylene rope. It's the same material right? WRONG! The material may be similar, but those types of polypro we has twisted construction with a only a tensile strength of 1,350 lbs. for 3/8" and 2,400 lbs. for 9/16".
Compare that with tube tow ropes of the same sizes with a strength of 2,375 lbs. for 3/8" and 4,175 lbs. for 9/16". As you can see, the difference in construction makes quite an impact on the performance. Add to the fact the tow ropes have pre-spliced eyes in them. If you purchase just standard rope you will have to tie a knot in it and knots will further reduce the strength of the line by up to 50 percent.
What length to choose
Most are between 50ft and 60ft – the length is not critical – be aware that a longer rope will give a more exciting ride as the whip will be greater – if you are towing younger kids at slower speeds then go for a slightly shorter rope.
Do not make the rope less than 25ft as this will be too close to the boat with a risk of contact between the tube and the back of the boat and also the pasengers nay suffer unpleasant fumes.
I already have a wakeboard or water ski rope. Why can't I just use that?
Ski ropes are made to take consistent loads. Tube ropes are made to take shock loading when the tube line goes completely slack and then quickly taught again. Not to mention many water ski tow ropes have a handle that cannot be removed.
