🍌 Nutrition & Fueling
On-water fueling is one of the most underrated performance levers in surfski racing. Whether you’re doing a 2-hour training paddle or a 6-hour race, what you drink and eat — and how you carry it — has a direct impact on how you finish. This page covers hydration systems, water bottles, and on-water fueling tools.

Water Bottles
A quality insulated bottle keeps water cold for 24 hours in the sun and heat. Wide-mouth openings accept ice and are easy to fill quickly at the launch. Most surfski paddlers strap a bottle in the cockpit or clip it to deck rigging.

Soft Flasks & Gel Flasks
Soft flasks compress as you drink and collapse flat when empty — no sloshing, no bulk. Reusable gel flasks let you pre-fill energy gel from a larger pouch and access it mid-paddle with one hand. Both are significantly more practical on a surfski than rigid bottles or single-serve gel packets.
Soft Flask — 500ml Compressible
HydraPak SoftFlask Speed 500ml
500ml compressible soft flask designed for hydration vests and running packs. Easy-open cap for one-hand access. Collapses flat when empty. Fits cleanly in a cockpit cup holder or deck bag.

Electrolytes & Hydration Tabs
Electrolyte replacement is essential on multi-hour paddles — you lose sodium, potassium, and magnesium through sweat long before you feel depleted. Effervescent tabs dissolve in your water bottle or bladder and are far more practical on the water than powders.
Electrolytes — Effervescent Tabs
Nuun Sport Electrolyte Tablets (6-Pack)
The benchmark electrolyte tab for endurance athletes. Gluten-free and vegan. 6-pack provides 60 servings across mixed flavors. Drop one in your water bottle or bladder before a long paddle.
