Riding Tips
by David Miner
Riding a DPV underwater is a lot fun and is exciting, but it requires practice, proper technique, and proper buoyancy control as well as several other things. Using a DPV extends your range on a dive and can be a great tool for exploration dives.
Properly positioning yourself on the DPV is essential. If you’re using a ride on DPV, positioning yourself for maximum streamlining is essential. The higher your position on the DPV, the more drag you create. More drag equates to slower speeds and increased battery use, which reduces the amount of time you run the DPV.
If you’re using a ride behind DPV and using a tow strap, it is essential that the tow strap be the right length so that your arm and DPV are properly extended in front of you. You want the DPV extended in front of you so that your elbow is slightly bent and the prop wash flows directly underneath your body. This is the most streamlined position and reduces drag. The tow strap is responsible for pulling you through the water. Typically, when using a tow strap, you only have to use one hand on the DPV. Many divers tilt the DPV on its side so that your hand is positioned on the top of the DPV. Many DPV manufacturers balance their DPVs so that this is easily done.
To steer your DPV, you mainly position your fins for direction. Tilting the DPV up or down allows you do go ascend or descend. You’ll find that even the largest DPVs are extremely maneuverable. Proper ascent and descent rates should always be observed while riding your DPV. Many times, it’s a good idea to do a swimming ascent with your DPV off as opposed to riding your DPV back to the surface.
DPVs provide the ability to extend the area you can cover underwater. Because of this, it’s important to plan and follow gas rules so that you have enough gas to make it back to where you began your dive. If the DPV failed, you would have to swim back towing the DPV. If you didn’t have enough gas, you could be in trouble. If there is a current, you should begin your dive by going against the current so that when you turn around, it is easier to return. Swimming with a DPV against a current could be very difficult and tiring.
If there are two different types of DPVs in your dive team, be aware that not all DPVs have the same performance characteristics. You must plan your dive on the slowest and shortest burn time DPV in the group. Dive planning based on the less performing DPV is essential at all times.
Proper technique, conduct, and planning are essential when riding DPVs. Don’t push your limits or exceed your capabilities. A DPV is tool and a fun toy, but can be dangerous and deadly if not used in the proper manner. Safety should always be number one so that you can have a fun, relaxing, and exciting time with your DPV.
