Subwing Underwater Towable Boards

Getting started

To make your Subwing ready for action you first have to assemble the Subwing by connecting the two wings with the swivel. swivel conveniently enables for quick assembly and disassembly of your Subwing for easy storage and transport.

Ho to Assembly Subwing Underwater Towable Board

With both wings facing the top side up (rope mounts facing up), simply place the ends of the swivel in each hole of the wings.

These holes have mirrored threads, meaning the swivel only fits one way. Check the inscribed directions on the side of the swivel’s rubber grip for which end corresponds to the correct hole (left or right). Now give the wings a small amount of pressure towards each other while screwing the swivel in the direction of the inscribed arrowheads on the swivel’s rubber grip. Continue screwing until the gap between the rubber grip and wing is about 1/4 Inch or 0,5-1 cm. You should barely be able to touch the metal with your little finger in the gap between the rubber grip and wing.

Note: Check the directions inscribed on the swivel’s rubber grip for correct assembly.

Getting in the water with Subwing

Make sure that the boat’s engine is always turned off while someone is entering the water or are close to the engine. Make sure that the rope doesn’t tangle around your body while the boat tightens the rope. With the rope tight and your hands firmly on the wings, signal the driver to give a small amount of throttle.Note: top side of the Subwing is the side of which the ropes are coming out of the rope connectors.

Tip: For beginners it may be a good idea to start with the Subwing up-side down. This will make it easier to stay on the surface and resurface from a dive, but harder to dive. In addition, the Subwing will not dive on its own when released in speed, but stay on the surface.

When towing the Subwing, there should always be a minimum of two people on the boat:

  • 1. Spotter – a person keeping an eye on the Subwing riders and informs the boat driver on the current status.
  • 2. Boat driver– should be focusing on maneuvering the boat and adjusting the speed according to the spotter’s directions.

Hand signals should be used when communicating between the boat and Subwing riders. Make sure that everyone has agreed on hand signals and are familiar with them before anyone gets in the water. An example of hand signals that can be used is thumbs up to go faster, thumbs down to go slower and a flat hand to stop.

Note: rider, spotter and boat driver should all have fully read the user and safety manual carefully before using the Subwing for the first time.

Note: Even though the Subwing floats, it will dive on its own if released at speed. To prevent damage, stop the boat immediately.

Board’s Tow rope

For towing the Subwing, always use a floating rope meant for tubes or other water sports. Preferably the towing rope should be attached directly at the center of the stern of the boat, as the forces from the rope while towing the Subwing can drastically impair the maneuverability of the boat. This is especially noticeable with smaller boats.

Tip: If your boat doesn’t have a rear center mounting point, use a short rope and connect its two ends on either side of the boat with the towing rope tied in the middle. This will center the pulling forces directly behind the boat.

Note: pulling forces vary while the Subwing rider moves through the water. This can impact the heading of the tow boat.

Your speed during underwater swimming

When towing the Subwing for the first time, start with a small amount of throttle, or just idling speed. Let the person in the water familiarize himself of how the Subwing behaves in the water before going any faster. Around 2-4 knots is the recommended towing speed of the Subwing.

Note: Under water, the sense of speed and the forces on the body increases drastically. Take into consideration that a speed around 4 knots is considered fast. Do never attempt higher speeds.

Board’s Maneuvering basics


To dive, simply tilt both of the wings downwards while holding on to the rubber grips. This will change the water flow over the wings similar to a rudder and will make you descend.


To resurface, simply do the opposite of diving. Point both wingsupwards and you will quickly return to the surface.

Barrel rolls

To achieve a successful barre roll, point the wings in opposite directions.Barrel rolls are usually done while underwater, attempting a roll on the surface leaves one wing in the air giving you a hard time completing a full rotation.

Moving to the sides

Do a partial barrel roll until you are in a sideways position. You can now point the wings in the same direction to move to either sides.

Tip: You can control the downward and upward speed by adjusting the amount of angle you are applying the wings. A bigger angle leads to a more aggressive and fast reaction while a small angle corresponds to a slow and easy response.

Note: Do not attempt barrel rolls, rapid turns or tricks before you are completely familiarized with the basics of resurfacing and diving.

Using the rope grip

rope grip located at the rear of the Subwing is used whenever one hand is needed. Use it when equalizing ear pressure, when signaling the boat or simply when trying our different riding styles. It can also be used as a carry handle.

Using the rope grip under water can be challenging for beginners and requires some training in order to fully master. Take in account that the Subwing will naturally start diving when holding on to the rope grip under water and transitioning back to the wing grips requires some technique.

Note: Subwing can spin out of control if one of the wing grips is used separately. Therefore, use the rope grip whenever one hand is needed. This applies especially when under water.

Tip: Experienced riders can maneuver the Subwing from the rope grip by using the entire length of their arms, lowering them to elevate, raising them to decline and twisting them to roll.

Transitioning from the rope grip back to the wing grips

When transitioning from the rope grip back to the wing grips it’s important to get the wings in a neutral or upward position before performing the switch, or else the wings can spin out of control. For this reason, we advise to gain some experience before attempting to use the rope grip. Tip: Check out our Youtube channel for a video tutorial on how to master the rope grip.

5 steps to prevent the wings from spinning out of control when transitioning from the rope grip back to the wing grips

  1. Hang by the rope grip to descend and equalize.
  2. When you want to switch to the wing grips, pull the grip close to your chest.
  3. Push the rope grip downwards in order to angle the Subwing upwards so the Subwing is no longer pointing in a downwards angle.
  4. Do the transition back to the wing grips. Move one hand to the wing grips while maintaining the other around the rope grip.
  5. Follow up with the second hand after establishing a firm grip around the wing grip with the first hand.
