Lifting and transporting a paddleboard safely

Why a SUP is genuinely hard to carry alone

Stand-up paddleboards are dimensioned for water, not land. A typical all-around board is 10′6″–11′6″ long, 32–34″ wide, and 5″ thick; the touring boards extend to 12′6″ or 14′. The weight (typically 12–18 kg for hard-shell, 8–12 kg for inflatable) is modest; the awkwardness is the issue. The board is too wide for a hip-carry to clear the shoulder, too long for a one-hand carry to balance, and too thick for a casual finger-grip on the rail. A user without a board-handle (the moulded recess in the deck near the centre of mass) is reduced to bear-hugging the rails or dragging.

The carry distance from car to water at most public beaches is 100–500 m — long enough that carry ergonomics, not just raw distance, matter. Knapik 2004’s military load-carriage review is built on marches measured in kilometres and loads measured in kilograms rather than a specific metre-scale distance where performance degrades; its consistent finding is that awkwardly-shaped or off-centre loads cost more, biomechanically, than a well-balanced load of the same weight (Knapik 2004 Knapik 2004) — a mismatch a 100–500 m carry is long enough to expose.

The board-handle and why it matters

Most modern boards include a moulded handle in the deck near the longitudinal centre of mass — usually about 18″ behind the centre of the deck. The handle is the design solution to the carry problem; it lets the user lift and carry with one hand, with the board balanced over the centre of mass, the long axis of the board parallel to the direction of travel, and the carry hand at the shoulder rather than overhead.

Knapik 2004’s load-carriage work consistently found that mass close to the body and centred over the support hand or shoulder produced the lowest metabolic and biomechanical cost (Knapik 2004 Knapik 2004). The board-handle carry approximates this almost perfectly — the load is at shoulder level (not overhead), close to the body, and centred. The shoulder load is roughly half what a side-carry produces and a third of what a one-hand-on-the-rail carry produces, by the lever-arm geometry the load-carriage literature has consistently quantified.

The implication: if your board doesn’t have a usable centre handle, the carry is a fundamentally different problem than the modern board the SUP literature presumes. Older boards or very long boards may need a strap or a two-person carry instead.

Side-carry vs over-the-head: the trade-off

Two carry techniques dominate the practical literature. The board-handle carry (board parallel to the side of the body, handle in one hand, board running along the user’s side at hip-to-shoulder height) is the default for short and medium distances. The over-the-head carry (board lifted over the head, balanced on the head and supported by both hands at the rails) is the alternative for longer distances or windier conditions.

Side-carry advantages: lower shoulder load, easier to set down quickly, hands free to manage the leash and paddle. Disadvantages: the board catches the wind broadside (a meaningful issue with a 32″-wide board on a windy day), the load is asymmetric (carrying on one side only loads that shoulder), and the board-tip can clip people in tight spaces.

Over-the-head carry advantages: the board catches less wind (oriented edge-on), the load is symmetric (both shoulders share), the board is out of the way of pedestrian traffic. Disadvantages: requires the user to lift overhead and balance — a movement many adults cannot complete safely — and produces a sustained shoulder-elevation load, consistent with Wilk 2009’s finding that restricted shoulder rotation predicts a substantially higher risk of injury in overhead athletes (Wilk 2009 Wilk 2009).

The honest framing: side-carry for short distances (under 100 m) and calm conditions; over-the-head for longer distances (100–300 m) and windy conditions, but only by users with intact overhead shoulder mobility and the strength to set the board down without dropping it.

Why smaller users carry the bigger penalty

Vanderburgh 2008’s body-mass-bias research — conducted on military fitness-test scoring rather than paddleboard carry specifically — is the often-overlooked half of the story (Vanderburgh 2008 Vanderburgh 2008): it found that lean body mass, not overall body size, is what predicts real occupational load-carriage and lifting performance — standard fitness-test scoring formulas actually under-credit larger, leaner personnel, who perform these physical tasks best. Separate from that finding, simple arithmetic on relative load still matters for SUP carry: a 15-kg board is 25% of body mass for a 60-kg adult and 17% for a 90-kg adult, and carrying a given absolute load generally costs a lighter person proportionally more effort. The implication for SUP carry: a smaller adult (typically smaller women, smaller adolescents) is carrying a substantially higher relative load than a larger adult, even with the same board.

This translates to two practical recommendations. First, smaller users should consider an inflatable board (typically 8–12 kg) over a hard-shell (12–18 kg) when carry distance is non-trivial — the relative-load math favours the lighter board even with the modest performance trade-off. Second, smaller users should be more aggressive about the over-the-head technique only at distances and conditions where the symmetric-load advantage outweighs the sustained-shoulder-elevation cost. For most smaller users, two short rests on a 200-m carry beat one continuous overhead carry.

The chronic-overuse shoulder pattern paddlers report

Wilk 2009 studied glenohumeral rotational-motion deficits in professional baseball pitchers and found that pitchers with a meaningful deficit faced a substantially higher risk of subsequent shoulder injury and surgery (Wilk 2009 Wilk 2009) — evidence that restricted shoulder range, not just raw workload, is a driver of overuse injury in overhead athletes. Schram 2016’s SUP-specific study didn’t track injury complaints at all — it found that six weeks of regular paddling produced large fitness and quality-of-life gains in previously sedentary adults (Schram 2016 Schram 2016). The carry mechanics are part of the cumulative load — perhaps 5–15 minutes of shoulder loading per session in addition to the paddling itself.

The mechanism: an overhead carry holds the shoulder in 150–180° of elevation for the duration of the walk. The supraspinatus tendon is compressed against the acromion through that range; the long head of biceps tendon is loaded; the subacromial bursa is squeezed. A few minutes per carry is well within the recovery window; a few minutes per carry across many sessions is the kind of cumulative shoulder loading that overuse research, including Wilk 2009’s pitching-shoulder data, associates with elevated injury risk.

The implication: rotate the carry technique across sessions. Use a board with a centre handle so the side-carry remains a viable default. Consider the over-the-head carry as a tool for specific conditions (wind, distance) rather than the routine.

Loading and unloading the car: the second risk window

The car-rack to ground transition is the single highest-injury moment in SUP transport, by both anecdotal report and the limited published data. The board sits 1.5–2 m off the ground on most car racks; the user must lift it down with arms extended overhead at full reach; the board is awkwardly shaped; the user’s feet are typically on uneven parking-lot surface. McGill’s broader spine-mechanics work has identified the loaded-overhead-reach with rotation as one of the two or three highest-risk back-injury postures, especially when combined with a fatigued or mid-distance user.

The technique cues that reduce the risk. Position the car so the long axis of the board can be lifted off the side rather than off the back (most racks support both). Use a rack pad that allows the board to slide forward and aft rather than requiring a vertical lift. Two-person lifts for the car-to-ground transition for any board over 12 kg, especially for smaller users. A ‘step-in’ rather than ‘reach-up’ technique — bring the board down to chest level first, then to ground — reduces the peak overhead load.

The economic case for a wheel-cart for distances over 100 m is good: a $40–80 cart converts a 200-m carry from a load-bearing problem into a wheeling problem, with the shoulder-load reduction Knapik 2004 quantified for any wheeled-versus-carried comparison (Knapik 2004 Knapik 2004).

What carry technique cannot fix

The honest framing. Carry technique covers most of the avoidable shoulder load — perhaps a 40–60% reduction in cumulative shoulder loading per session relative to the worst-case bear-hug carry, based on the lever-arm and load-carriage estimates the literature provides. Technique does not eliminate the shoulder load entirely; a 12–18 kg board is a real load regardless of how it is carried. Technique also does not cover users with pre-existing shoulder pathology — a paddler with active rotator-cuff irritation should not be doing the over-the-head carry under any technique.

The case for the carry-mechanics conversation is twofold. First: shoulder strain from repetitive overhead loading is a well-established overuse risk in throwing and reaching athletes, and the carry is one of the contributors most paddlers don’t think about — even though Schram 2016’s SUP-specific study measured fitness and quality-of-life gains rather than injury rates (Schram 2016 Schram 2016). Second: most paddlers will adopt the carry pattern they accidentally develop in their first few sessions, and that pattern persists for years. A small amount of explicit attention early in the practice is consistent with Wilk 2009’s finding that restricted shoulder rotation predicts a meaningfully higher injury and surgery risk in overhead athletes (Wilk 2009 Wilk 2009).

Practical takeaways

• A 12′ SUP weighs 12–18 kg and is dimensioned poorly for any normal carry; carry distance and technique are real fitness-and-safety variables (Knapik 2004).
• The board-handle carry (board at side, hand at shoulder) is the default for short distances; the over-the-head carry suits longer distances and windy conditions but sustains the shoulder in an elevated position linked to the overuse-injury risk Wilk 2009 documented in overhead athletes.
• Smaller users carry a higher relative load and should consider inflatable boards (8–12 kg) for non-trivial carry distances.
• Schram 2016 found that six weeks of regular SUP training produced large fitness and quality-of-life gains in previously sedentary adults; carry mechanics are worth attention in their own right.
• Rotate carry techniques across sessions; the side-carry should remain the default with overhead used selectively.
• The car-rack to ground transition is the single highest-injury moment; two-person lifts for boards over 12 kg, especially for smaller users.
• A $40–80 wheel-cart converts a 200-m carry from a shoulder-load problem to a wheeling problem — favourable cost-benefit for regular paddlers.
