Adventure brief
NRS Slipstream 139 — a 14' fishing raft that reaches Montana’s shallow runs and stands up to bigger rivers
The NRS Slipstream 139, outfitted by Hatch Adventures, is a purpose-built 14-foot fishing raft that pares down what a river platform needs: shallow-water performance to reach runs other rafts can’t, enough room for up to three anglers or fewer anglers plus more gear, and a suite of built-in systems—storage, angler seats and frame, and an internal anchor—that make it a versatile choice from quiet streams to pushy river water.
Montana’s rivers offer a challenging and rewarding playground for anglers seeking both tranquility and adrenaline. Hatch Adventures invites anglers to tackle these waters aboard the NRS Slipstream 139, a 14-foot raft engineered for versatility across Montana’s diverse waterways—from shallow, whispering streams to roaring, rugged rivers. Positioned just outside of Bozeman in Belgrade, Hatch Adventures serves as a key outfitter for anglers aiming to immerse themselves in some of the West’s finest fishing environments.
The NRS Slipstream 139 is purpose-built to meet the demands of Montana’s varied river systems. With a robust welded seam tube construction and triple-chamber design, it’s ready to withstand the scrapes and bumps of rocky beds, ensuring safety even in puncture scenarios. Its 6-inch drop-stitch floor stands out, offering exceptional stability that negates the need for bulky casting platforms. This stability, paired with slip-resistant padding, means anglers can focus on precise casts without worrying about footing.
Designed to comfortably hold up to three anglers, the raft is outfitted with bow and stern angler seats, thigh hooks for casting stability, and an innovative internal anchor system controllable from the rower’s seat with a 35-pound pyramid anchor. Efficient storage solutions include lockable dry boxes and organizational dry bags, perfectly accommodating gear and keepers alike. Additionally, the large Canyon Cooler onboard keeps refreshments cold, crucial for extended days on the river.
Hatch Adventures fits perfectly into Montana’s outdoor scene, offering rental packages that give anglers access to remote waterbodies unreachable by larger boats. Whether floating the scenic stretches of the Gallatin River or navigating the technical whitewater sections of the Madison, this raft handles it all. The combination of advanced raft features and Hatch Adventures’ local expertise makes for an unforgettable experience rooted in both challenge and comfort.
Route Schematic
Route schematic
Typical outings play to the Slipstream’s strengths: reach shallow runs, hold in pushier currents, and fish on anchor.
Shallow‑stream access
Use the raft’s shallow‑water design to reach runs and eddies that larger, deeper boats can’t access.
Pushy‑river sections
Transition into steeper, pushier river water where the raft’s white‑water engineering and robust construction let it hold a line and track reliably.
Anchored casting and drift control
Deploy the internal anchor from the rower’s seat to hold position for precise casting or to stage for a drift.
Renters must be at least 21 to reserve the raft; there is no age limit for riders.
Highlights
Outing Highlights
White‑water engineered, shallow‑water capable
Welded‑seam tube construction, upper and lower wear pads and three separate chambers give the Slipstream 139 durability and redundancy, while its shallow‑water tuning permits access to runs that deeper hulled rigs cannot reach.
Purpose‑built layout for anglers
Space to carry three anglers plus gear, an NRS Lo‑pro fishing frame with extra D‑rings for lashing equipment, stern and bow angler seats and thigh hooks provide a stable, practical casting platform.
Built‑in anchoring and stability
A controllable internal anchor system—operable from the rower’s seat and supplied with a 35‑lb four‑sided pyramid anchor—lets anglers hold position for casting; the 6" drop‑stitch floor and slip‑resistant pad add stability without needing a raised casting platform.
What the day feels like
What being on this raft feels like
The Slipstream 139 moves between quiet, shallow runs and more energetic river water with a rationale of stability and utility: a low‑profile hull to sneak into skinny water, a firm, slip‑resistant deck for casting, and integrated systems that let anglers control position and organize gear without constant reconfiguration.
