Highlander 100 vs. 120 vs. 140T: which AirTrek to buy

The Highlander 100 is the small-water inflatable; the 120 gives you more room and capacity in the same packed footprint; the 140T is the tandem for two-person days.

The Highlander AirTrek line is the answer for anyone who can't store a 12-foot rigid kayak in their life. All three pack to a trunk-sized bag, all three are real fishing boats, and all three take the Traverse Pedal Drive or a Hobie / Pelican / Vibe / Lightning fin drive via our Highlander Fin Drive Mount Kit.

Here's how they differ.

A few capacities on the inflatable line are still being finalized for the public site. If you want a hard number for your specific use case, ping us and we'll confirm before you order.

Single-chamber AirTrek construction — and why

All three Highlanders are single-chamber designs, not multi-chamber. That's a deliberate choice. A single, large, properly engineered chamber with the right drop-stitch construction gives you a flatter, stiffer floor and deck than stitching together two or three smaller chambers. The trade-off: in the very rare case of a puncture, the whole boat softens (versus a multi-chamber where you'd lose one and stay afloat on the rest). For real-world fishing on water you can swim back from, the stiffness win matters more.

You inflate to 10–12 psi. Don't trust the cheap pump gauge that comes with most pump kits — they read low by 1–2 psi. We recommend a separate digital pressure gauge for the first few inflations until you know what 12 psi feels like under your hand.

Highlander 100 — the smallest footprint

If you're in an apartment, drive a sedan, or fly to fish, the 100 is the easiest yes. Inflated, it's a 10-foot solo kayak. Packed, it fits in the kind of bag that goes in a trunk or a closet.

Heads-up on rigging: Quad Rails on the 100 come in 44" only and install via flush-mount inserts. The longer rails in the line aren't supported on the 100 hull.

Highlander 120 — same packed size, more boat

Two more feet of length over the 100, same packing footprint when deflated. The 120 is the AirTrek for someone who wants the inflatable benefit and the room to load a bit more gear without going tandem. All Quad Rail lengths fit the 120.

Highlander 140T — the tandem

Two seats, 14 feet inflated. The 140T is the family / partner / "two kids and a dog" inflatable. Same Traverse Drive option (likely — confirm at order if you're committing on the drive), same Fin Drive Adapter path via the Highlander Mount Kit.

If you're solo-fishing the 140T some days and tandem-fishing it others, that's fine — just plan the seat layout (Horizon Elevated Perch x2 vs. perch + Treklite) before you rig.

Inflation, transport, and pack-down

Inflation time: realistically 6–10 minutes with a decent dual-action pump, then a few cycles to top off to 10–12 psi.
Deflate / pack: don't fold creases at pressure. Drop the pressure first, fold along natural seams, never store wet at pressure.
Trunk / car-trunk reality: a sedan trunk handles a 100 or a 120 in its bag. The 140T is bigger packed than the solos — still manageable for an SUV or a larger sedan trunk, tight in a coupe.
Storage: dry and rolled (not folded), out of direct sunlight when stored long-term. Inflation at storage pressure (~5 psi) is fine; full pressure long-term isn't.

Drive setup — Traverse or fin

All three Highlanders take the Traverse Pedal Drive (Cajo's drive, 10:1 gearbox, instant reverse). They also take a kick-up fin drive through the Highlander Fin Drive Mount Kit — which is a different kit than the rigid Fin Drive Adapter, so make sure you order the Highlander-specific version. Compatible fin drives include:

Hobie Mirage Drive 180
Pelican fin drive
Vibe Hero 2.0-era fin drive
Lightning Kayaks fin drive

Not compatible: Hobie 360 (integrated with the Pro Angler 360 hull only).

How to pick in one sentence

Smallest footprint, solo, smaller water → Highlander 100
Same pack size, more room, all Quad Rail lengths → Highlander 120
Two-person fishing → Highlander 140T

A real-world honest take (100 vs. 120)

Most Highlander shoppers go back and forth between the 100 and 120 before deciding. The truth is both are good boats and you'd be happy on either. If you're genuinely on the fence:

You'll regret the smaller boat more often than the bigger boat. Two extra feet of deck space rarely feels like too much; tight deck space comes up every trip.
Unless storage is the deciding factor. If you live in an apartment or your car is small and an extra foot of packed bag matters, the 100 is the right call.
