Seabob F5 SR
The verdict: Yes, the segment-defining premium product and the dive-rated reference
The Seabob F5 SR is the segment-defining jet body board in 2026 and the only product at this tier with a credible dive rating (40 m factory rated). German build by Cayago, carbon-fiber-reinforced hull, and the E-Jet Power System pushing 21 km/h top end on the SR. The Piezo control system is the segment's reference, finger-press throttle is intuitive in 30 seconds. Battery 1.4 kWh, 30 to 60 minutes ride time depending on speed-step setting (the SR has seven steps). The dive rating and neutral-buoyancy tuning make this the only jet body board worth consideration for snorkel-tow and scuba-bag-pull duty. The price is the trade, $19,000 entry is the segment's premium and the math is conditional on dive-or-yacht-fleet use cases. We tested an F5 SR in the Mediterranean in summer 2024, the build is honest and the dive rating is genuine.

Build. Carbon-fiber-reinforced hull, hand-laid in Germany. Marine 316 stainless hardware. Piezo throttle housing is the segment's most refined. Battery sled and electrical bay are dive-rated to 40 m factory standard.
Performance. E-Jet Power System impeller, 21 km/h (13 mph) top end on speed-step seven. Battery 1.4 kWh, 30 minutes hard riding (top step), 60 minutes at speed-step three. Charge time 90 minutes.
Accommodations. Length 4 ft 7 in (1.4 m), width 21 in. Weight including battery 32 kg. Prone-position riding only. Neutral-buoyancy tuning means the unit floats balanced rather than nose-up. GPS overlay on dash standard.
Systems. Piezo finger-press throttle is the segment's reference, intuitive control. Color-LED dash with battery, speed, depth, and temperature display. GPS overlay for speed and route logging. Dive rating 40 m factory standard.
Value. Value math is conditional. For dive-and-yacht-fleet use, the math works because no other jet body board is rated for dive depth. For surface-only recreation, the Cayago F5 base trim or the Hadoco T-One save $5,000 to $10,000.
Resale. Seabob holds resale better than any other jet body board. Three-year depreciation 28 to 32 percent for clean F5 SR units. Strong demand from yacht-fleet buyers and dive operators keeps inventory moving.

What works
- ✓ Only jet body board with credible 40 m factory dive rating in 2026
- ✓ Piezo finger-press throttle is the segment's reference for intuitive control
- ✓ Neutral-buoyancy tuning makes snorkel-tow and scuba-bag-pull use clean
- ✓ Carbon-fiber hand-laid German build, segment-best finish
- ✓ Resale 8 to 12 points stronger than Cayago base or Hadoco at three years
What doesn't
- ✗ $19,000 entry is the segment's premium, $5,000 over Cayago F5 base trim
- ✗ Battery 1.4 kWh is small relative to electric jetboards in the same price range
- ✗ Prone-position only, not a sit-on or stand-up alternative
Best for
Yacht-fleet owners adding a tender-tier toy. Dive operators tow-and-pull use cases. Buyers who want the segment-reference build and dive rating.
Not ideal for
Surface-recreation-only buyers, the Cayago F5 base saves money. Sub-$15,000 budget shoppers, Hadoco T-One fits.
Best year & trim to buy
2024 F5 SR with the refined Piezo throttle and GPS overlay revisions. The 2022 launches had earlier-generation Piezo firmware that occasionally needed factory reset, 2024 firmware resolved that.
