★★★★★

The Joyride is by far the best board I have ever owned. I feel completely at ease in the ocean waves or the shallow waters of the mangroves.

JASON P., Paradise paddleboard
Paradise
★★★★★

The Hydrus Paradise tracks and glides very well for an inflatable paddle board. It's easy to sprint between 5-6 mph on flat water.

— JASON P.
Mandy M., JoyRide XL paddleboard

This board is extremely stable and handles the water like no other. Payette lake is notorious for its waves and wind.

Erich C., Paradise paddleboard

It's fast, and surprisingly stable once I got used to the narrower profile. The quality has been fantastic.

I message the company and received a phone call from Jason (the man himself) a few hours later.

We love this thing. Half the time we're using it as an inflatable dock at the lake that we can jump off of or just relax on.

First trip out was down Silver Springs to see manatee, river otter, blue tilapia, and so much other wildlife.

Luke E., AXIS 98 paddleboard
AXIS 98
★★★★★

I have had 4 Hydrus hard boards and the Axis 8'8" is my 1st inflatable from them. It feels unlike any other iSUP I have tried.

— Luke E.
Billy T., JoyRide XL paddleboard
JoyRide XL
★★★★★

Super stiff and stable, tracks really well and has more maneuverability than I'd have expected for its size. The material and build looks bombproof.

— Billy T.

Angela and Jason made the whole process of buying my Hydrus Axis an absolute pleasure from first contact to my board arriving.

— David B.

I bought it because I was looking for something durable for my size (6'4", 300lbs). I have to say I am extremely happy with it.

If you're on the fence about this board, do yourself a favor. I have not fallen off this board even while paddling in wavy and rough ocean waters.

— JIMMY L.
Allan, Paradise paddleboard

★★★★★

I upgraded to this board from an Atoll 11'. This board tracks really well and feels firm and stable underfoot.

Jason V., Paradise paddleboard
Paradise
★★★★★

We discussed other options including the JoyRide, but based on my input and background Jason recommended the Paradise and I could not be happier.

— Jason V.
Brandon S., JoyRide XL paddleboard

First iSUP I've owned and it's phenomenal. I spent over 40 hours researching various boards and was referred to Hydrus by a reputable blogger.

INCREDIBLE board. Super stable with speed too. Don't hesitate. I can't imagine any other brand being remotely close to Hydrus.

Quick Answers

Common Questions About This Board.

Both are quick-turning boards. The Cake is slightly faster end-to-end with a balanced feel. The BreakBeat is quicker in the turn but slightly slower across the wave. If you want all-around versatility, pick the Cake. If you prioritize tight maneuvers, pick the BreakBeat.
The 5 foot 2.5 inch by 23 inch HV size is for heavier riders or paddlers wanting more float. Adds noticeable lift on smaller waves while keeping the Cake's outline and rocker. Pick HV if you're over 200 lbs or like riding mushier conditions.
The Cake is shaped for river surfing first. Many riders take theirs to ocean waves and have a great time, but the rocker and rail are tuned for river-wave geometry. For ocean-priority surfing, check our Armalight ocean line.
