The last busy weekend is over. Tubes are coming back from the water, seasonal staff are wrapping up, and the easiest next step is to stack everything out of the way. Before you do, capture what this season taught you.
For waterparks, river outfitters, resorts, and rental programs, an end-of-season tube audit should answer three questions: What do we actually have? What needs attention? What will we need when operations pick up again? A count alone cannot answer all three.
Use the process below before seasonal storage—or during a quieter operating period if your location stays open year-round.
1. Count by model, not by pile
“We have 100 tubes” is a starting point, not a purchasing plan. Separate the inventory by model or SKU, size, rider format, and any variant that matters to your operation. A surplus of doubles does not necessarily solve a shortage of singles, and similar-looking products may have different intended uses.
Reconcile equipment from every location: launch points, return areas, vehicles, storage rooms, and anything already set aside for review. Keep sold stock, customer-owned equipment, and rental inventory separate where applicable. Give each unit an identifier in your records, or use clearly defined batches when individual tracking is impractical.
Write down the count before moving equipment into storage. Otherwise, a tube that moves from the inspection area to a shelf can easily get counted twice.
2. Give every tube a clear status
Inspect according to the product's supplied instructions and your operation's procedures. Include the material, seams, valves, handles, attachment areas, and any seating or bottom components. Record the location of a concern, not just “damaged.” A full-product photo plus a close-up is much more useful later.
Use three inventory statuses:
- Keep: No concerns identified during the required inspection. Record the inspection date; this status does not replace checks before the next use.
- Hold for review: A leak, loose component, unusual wear, missing information, or another concern needs a product-specific decision. Separate these units from usable inventory and do not count them toward opening-day supply.
- Retire: The unit has been determined unsuitable for further service under the applicable product guidance and operating procedures. Keep it clearly separated so it cannot accidentally return to the rental rotation.
Do not turn the audit into an improvised repair session. If a repair may be appropriate, confirm the method for that exact product and complete the required follow-up checks before changing its status. For WaveCraft product concerns, gather the model, purchase reference, photos, and quantity affected for a Product Claim & Support Request.
3. Look for patterns before ordering replacements
Ask the people who handle the tubes every day what slowed them down. Which formats ran short on busy days? Which were frequently left unused? Where did staff notice repeated abrasion, awkward carrying, or storage problems?
Separate observations from explanations. “Six tubes show wear in the same area” is useful evidence; “the launch surface caused it” is a hypothesis until reviewed. Note where the products were used and handled, and photograph relevant contact surfaces without including guests or personal information.
This step can change the next purchase. You may need more of a particular format, a different handling routine, or a discussion about product suitability. Reordering the same mix without reviewing the season can carry the same problems forward.
4. Calculate the gap by tube format
Start with the number of usable units you plan to have available, based on your own demand records and operating requirements. Add a separately chosen spare allowance, then subtract the units confirmed for continued service and suitable incoming units with confirmed delivery before they are needed.
Planned purchase quantity = operating target + spare allowance − usable retained inventory − confirmed incoming inventory.
For example, suppose an outfitter plans to operate with 120 single tubes and chooses 12 additional spares. Its audit identifies 91 usable singles, 9 on hold, and 10 retired. With no confirmed incoming stock, its planning gap is 120 + 12 − 91 = 41 single tubes. The nine units on hold stay outside the usable count unless they are cleared for service.
These numbers are illustrative, not a recommended fleet size or spare ratio. Run the calculation separately for each required format. If it produces a negative number, review the surplus rather than treating it as a negative order.
5. Store the equipment with the records
Complete cleaning, drying, deflation, and packing according to each model's instructions. Check folds and less-visible areas for remaining moisture, and choose a protected storage location suitable for the product. Our tube care guide covers the underlying routine.
Keep the inventory record tied to its storage location: shelf, bin, room, or clearly defined batch. Record unresolved issues and assign someone to follow up. Schedule a review before reopening so a question discovered in autumn does not become an opening-week surprise. Stored equipment still needs the required inspection before it returns to use.
Your end-of-season audit checklist
Copy these fields into a spreadsheet or inspection sheet:
- Identify: Model/SKU, size or format, unit or batch identifier, and quantity.
- Inspect: Date, reviewer, observed condition, and photo references.
- Decide: Keep, hold for review, or retire; next action and person responsible.
- Locate: Storage location and date packed.
- Plan: Operating target, spare allowance, usable count, confirmed incoming units, and purchasing gap.
- Follow up: Review deadline and required checks before returning to service.
Turn the audit into a focused product conversation
If the result is a straightforward replacement need, compare the current in-stock assortment against the exact format and quantity required. For a larger fleet plan or a change in specification, request a commercial quote with quantities by model or format, intended use, delivery destination, and your target in-service date. Confirm availability and timing during the quotation process.
The most useful thing you put away this season may be the record of what worked—and what needs to change before the next one.
