Learn the SUP draw stroke: move your board sideways to a dock or other paddlers from a staggered stance, with the sculling variant and safety data.
The honest answer: the draw stroke is a small, inconspicuous stroke that moves your board sideways without turning it. You need it mainly at a dock, when mooring or next to another paddler. A training series by a SUP brand describes it exactly like that: a draw stroke moves your board sideways and is useful when pulling up to a dock or coming alongside another paddler [1]. There are two variants: the regular draw stroke and the sculling draw [1].
The skill is not a main stroke. In the VDWS instructor exam the content is the C stroke, J stroke, crossbow turn and pivot turn between two buoys [5]; the draw stroke does not appear there. So it is a tool for advanced paddlers, not exam material. I found no measurement study on the draw stroke. The description comes from an instructor guide [1], which is practice knowledge.
A draw stroke is a conversation with the water, not a feat of strength: quiet, even, patient.
Realistically you need a few practice sessions until you move the board sideways without it turning (experience value). A motion analysis of 18 recreational paddlers shows that the shoulder uses a large range of motion when paddling, more kneeling than standing [4]. The draw stroke brings an unfamiliar one-sided arm movement, so you go slowly.
Take a step back with the foot the leash is attached to and turn both toes about 45 degrees towards the rail of the side you face [1]. The staggered stance gives more stability and opens you up for one-sided strokes [1].
Milestone (practice): 5 minutes paddling in the staggered stance without wobbling.
Reach out on the open side. The blade lies parallel to the rail of the board, the power face of the blade facing you [1].
Submerge the blade slightly behind your feet and pull it to the rail of the board [1]. The board moves sideways towards the blade. Do not pull it against the board: contact with your own board was a common injury mechanism in two studies [2][3].
Milestone (practice): 3 pulls in a row that move the board sideways without turning it.
Lift the blade out and begin again [1]. Several short, even pulls are better than one long one.
Plant the blade away from the board, slightly behind the feet, at an angle of 45 degrees [1]. Sweep it forward in one flowing motion, change the angle and sweep it back; the blade stays in the water, like spreading butter on bread [1]. The movement is barely visible. Pick a landmark to notice the sideways movement [1].
At a dock or next to other paddlers the danger is low but real. In a study of 240 paddlers 3.63 injuries per 1000 hours were counted; the shoulder was the most frequently affected spot at 32.9 percent [3]. In a second with 438 paddlers the rate was 1.95 per 1000 hours, with overuse and contact with board or ground as main mechanisms [2]. The draw stroke is a one-sided arm movement, but no study has linked it to injuries.
If you paddle in flowing or wild water, other rules apply: there the risk was highest according to the survey [2]. Use the draw stroke there only with experience. Wear flotation and leash according to the situation. This guide explains and motivates, it does not replace a supervised course.
Try the draw stroke first at a dock with a gap. Lie alongside the dock without touching it and then pull yourself closer in small strokes. Once you manage that without wobbling, you can do it next to another board without contact. The landmark helps you notice the movement you barely see [1].
To move your board sideways, for example when pulling up to a dock or coming alongside another paddler [1]. For normal paddling you do not need it.
The regular draw stroke submerges the blade parallel to the rail and pulls it in [1]. In the sculling draw the blade stays in the water and performs a flowing forward and back movement with a changing angle [1].
In the staggered stance: one step back with the leash foot, both toes about 45 degrees to the rail [1]. It is more stable and opens you up for one-sided strokes.
Not especially, but contact with your own board was a common injury mechanism [2][3]. Do not pull the blade against the board. The shoulder is the most common injury site [3].
