Inflatable kayak: calculate total load before buying
Before comparing prices, calculate the mass of the whole crew and everything that will travel in the kayak. Then check the person limit and maximum payload separately for the exact variant. The example uses the ITIWIT X100+ 2P; passing both tests does not guarantee stability, comfort or safety in particular conditions.
Worksheet to complete
| Item | How to establish it | Your mass |
|---|---|---|
| Each person | Current mass, separately | ___ kg |
| PFDs / buoyancy aids | Weigh the complete set | ___ kg |
| Dry bags, food and clothing | Weigh after packing | ___ kg |
| Water | 1 litre of water ≈ 1 kg; add the container | ___ kg |
| Phone, first aid, repair items and other equipment | Weigh together | ___ kg |
| TOTAL LOAD | Add every item | ___ kg |
Worked example with explicit assumptions
| Assumption | Mass |
|---|---|
| Person 1 | 78 kg |
| Person 2 | 64 kg |
| Two PFDs | 2.4 kg |
| Dry bag and food | 12 kg |
| Water including container | 3 kg |
| Clothing | 2 kg |
| Phone, first aid and repair items | 1 kg |
| Total | 162.4 kg |
| 195 − 162.4 | 32.6 kg arithmetic difference |
Two independent decision conditions
| Check | Condition for the example variant | Result |
|---|---|---|
| Person count | No more than 2 | 2 people: passes |
| Total load | No more than 195 kg | 162.4 kg: passes |
| Identification | Ref. 8511866 | Confirm with a label photograph |
Seller message — copy and complete
The message asks for the reference and documentation because one series name may cover several sizes. A seller's reply is not a guarantee of condition.
Decision after the calculation
| Situation | Action |
|---|---|
| Person or payload limit exceeded | Reject the variant for this plan; do not remove safety equipment to fit under the limit. |
| Variant or limit not confirmed | Pause the decision and request the label and instructions for that exact item. |
| Both limits pass | Compare cockpit dimensions, seating, transport, weather, water and local requirements; if uncertain, consult an instructor or rent a comparable variant. |
