Sizing Guides

Here are our links to both sizing guides and buying guides on our products, all these are here to help you make an informed decision on what size or product will work best for you.



Let’s face it, we all ride hard and the toys we play on are bound to take some abuse. Nearly all manufacturers understand this and provide a warranty against defects and workmanship. Each new product sold by Skiforce is covered by the individual manufacturer’s warranty. Please check the manufacturer’s website for information regarding their specific warranty policy. The manufacturer will make all warranty decisions. All return shipping costs are the responsibility of the buyer. As an Australian Wake and Waterski Retailer we can only warranty products purchased from our store and website. Please have proof of purchase at Skiforce available when dealing with any warranties.


Step 1. Determine whether the damage should be covered by warranty. Here are a few things that are NOT covered by warranty:

Normal wear resulting from standard usage that occurs over time. (chipped topsheet, sun faded topsheet, etc)

Damage resulting from contact with objects. (Rails, kickers, logs, stumps, little kids, skiers, etc.)

Damage to product resulting from improper care or unnecessary roughness. (throwing it around on the bank, product flying off of board racks, etc)

Parts, hardware, accessories that were lost or have gone missing AFTER receiving your shipment.

Step 2. Email us about your warranty and include CLEAR and detailed pictures explaining the problem. Blurry pictures will not be accepted.

If you have any questions, don’t hesitate to give us a call. We want to see you back out on your product as much as you want to use it and try to get you a response within 48 hours of receiving the product.

Step 3. We will contact you with further instruction.

The next step varies by manufacturer and we will provide you with all the details for the next step. If your warranty claim is accepted you will have to ship your product back to us so that we can confirm the warranty with the manufacturer. Return shipping on warranty claims is the responsibility of the buyer. The manufacturer or Skiforce will cover shipping charges on all items replaced or repaired under warranty.

Let us know if you are in a rush and would like to pay extra for express shipping on your warranty return.
