OARS USA SCULLING oarsAll oars at Croker Oars USA are custom made to order. Each shaft is individually tested for stiffness and weight.

They are made to suit each individual and each individual has different needs.

The shaft of an oar receives a lot of

attention at Croker Oars. We invest

many hours into designing, developing,

and trialling our products and believe

our range of shafts give every rower an

opportunity to match their skill level with

what they want to feel in the water.

Before assembly each shaft is deflected,

weighed and matched to its identical

partner to give you the best pair of oars

possible.

Contact us regarding your abilities and

we will offer suggestions for a shaft we

believe would be best suited to you.

Product Guide

SCULLING Shafts

S39 ARROW Series - Small diameterThese shafts are made using high modulus carbon, recently used in the America’s Cup boats.

They have multiple layers of thin carbon plies at various angles to achieve a balance of strength, stiffness, torsional stiffness and very light weight. These thin shafts have less aerodynamic drag

than normal shafts and because they weigh less have less rotational inertia.

Shaft Type Weight Usage Blade Handle

S39 Soft 1240gm

Designed for highly competitive lightweights, juniors, women and masters who demand the finest and lightest sculling oars in the world. Ideal for athletes with 2km erg scores slower than 7:00, water times in the 1x around 7:45 or slower for 2km. These shafts are fitted with the new Arrow Sculling Blade. This high performance blade is the latest development from Croker Oars. It is designed for athletes who want the best and exhibit good technique.

A,CA Adj

S39 1250gm

Designed for world class, elite level and highly competitive openweight athletes who seek an uncompromising sculling oar, the ultimate tool for propulsion on the water. Scullers with 2km erg scores faster than 6.30 and water times in the 1x faster than 7:30 for 2km are well matched to the stiffness of the S39. These shafts are fitted with the new Arrow Sculling Blade. This high performance blade is the latest development from Croker Oars. It is designed for athletes who want the best and exhibit good technique.

S7 SeriesThese shafts use multiple layers of thin carbon plies at various angles, to achieve a balance of

strength, stiffness and torsional stiffness. Standard diameter shafts.


S7 Soft 1400gm

Full carbon shafts are the traditional Croker diameter, but incorporate the materials and techniques now utilized in our Arrow shafts. The shafts have superior torsional resistance compared to the S4 models, but the deflection under load is comparable. With a slightly more forgiving introduction to the full load at the catch, the S7 Soft are appropriate for rowers below the standards for the regular stiffness S7, or those preferring a little more flex. As with all of our elite soft shafts, it is well matched to scullers with 2km erg scores slower than 7:00, water times in the 1x around 7:45 or slower for 2km, or for those who desire a slightly more forgiving feel at the catch.

S, CA Adj

S7 1400gm

With superior torsional strength over the S4, these full carbon shafts incorporate the materials and techniques now utilized in our Arrow shafts. The S7 are appropriate for elite level scullers seeking just a little firmer connection than offered by the S4 regular full carbon shafts. It is well matched to scullers with 2km erg scores faster than 6.30 and water times in the 1x faster than 7:30 for 2km.

SCULLING Shafts

S4 SeriesThese shafts are full carbon shafts made using various layers of standard modulus carbon. They

achieve a balance of maximum strength and minimum weight.


S4 Soft 1300gm

These 100% carbon shafts and exhibit crisper catch and allow higher rating than our elite level S2 Soft models. They are ideal for juniors, women, as well as men below the pre-elite level. It is also popular choice for smaller elite openweight women racing the single scull. It is well matched to scullers with 2km erg scores slower than 7:00, water times in the 1x around 7:45 or slower for 2km, or for those who desire a slightly more forgiving feel at the catch.

S,CA Adj

S4 1380gm

These are the premiere sculling shafts for men’s senior and elite competition, as well as world-class elite women. The shafts are 100% carbon and exhibit crisper catches higher rating than our elite level S2 models. This has been the oar for anyone pursuing National Team goals, but also for anyone who wants every mile to feel exquisite. The recommended 2km erg score is 6.30 and faster, or a water time in the 1x for 2km faster than 7:30.

S,CA Adj

S2 SeriesThese shafts are made from uni-directional carbon and woven. They achieve good

strength with light weight.


S2 Soft 1410gm

The lightweight feel and elite performance of these oars is superior to that of heavier oars in common club circulation. They are constructed of 80% carbon and 20% fibreglass and are the definitive “step up” for dedicated scullers, but still at an affordable price. They are ideal for juniors, women, as well as masters men. It is also a popular choice for smaller elite women racing the single scull. It is well matched to scullers with 2km erg scores slower than 7:00, water times in the 1x around 7:45 or slower for 2km, or for those who desire a slightly more forgiving feel at the catch.

S2 Series cont.These shafts are made from uni-directional carbon and woven. Then achieve good

strength with light weight.


S2 1430gm

With a distinct lightweight feel and elite performance that is superior to the heavier oars in more common circulation, these oars are the definitive “step up” for dedicated scullers, but still at an affordable price. They are constructed of 80% carbon and 20% fibreglass. These shafts are an excellent choice for anyone seeking to win at the national racing levels in junior, elite, and masters competitions. The recommended 2km erg score is 6:30 and faster. The appropriate 2km water time in ideal conditions is 7:30 and faster.

S,CA Adj

S3 SeriesThese multipurpose shafts are made from glass and carbon. They have recently been upgraded

to increase toughness making them more suitable for general club activity.


S3 1550gm

With a shaft construction mix of 50% carbon and 50% fiberglass, the S3 is the recommended oar for club use and shared equipment situations. The S3 shaft has the same stiffness as the S2 Soft, but is significantly more durable, making it ideal for fleet purchasing in club or scholastic sculling programs. They are excellent for racing at all levels and for high performance school use. They have the same shaft stiffness as the S2 soft. With the heavier shaft weight, the S3 is less sensitive in high winds and bad weather. They have more weight in hand than our elite S4 and S2 shafts and therefore offer more stability during the recovery phase for the developing rower. The S3 also enjoy popularity among scullers who enjoy open or rough water.

S,CA Adj

S6 TrainersThese all glass shafts offer toughness and flexibility.


S6 Trainers 1800gm

With 100% fiberglass shafts, the S6 is designed for the rougher environment of novice and learn-to-row levels. The softer shaft reduces the risk of overuse injuries, especially in junior rowers. The increase in weight makes them the perfect oar for beginners, with less propensity for rising up in windy situations or overzealous movements. Given their durability and fleet longevity, the S6 are a highly economical oar for the instructional levels of any program. The S6 also enjoy some popularity among scullers who enjoy open water rowing events.

SLICKThe Slick blade is available with closed edges, which improves the blades durability and overall performance.

The low volume blade enters the water quickly and quietly and floats low in the water. The longitudinal curvature is perpendicular to the tip and so is in line with the flow of water. It has a constant pitch across the tip and all lines parallel to the tip. The gentle asymmetric curvature of the blade assures a clean release from the water with every stroke. Slick blades are visibly cleaner than other blades. It does not exhibit any negative tendencies during recovery or in bad weather.

Since the Slick blade’s introduction it has been extremely successful at all levels of rowing.

All S6, S3, S2, S4 and S7 shafts.

S39The latest computer designed blade especially manufactured for the Arrow shaft. These sculling blades which are designed to fit on the smaller shafts, feature thin edges, low wind resistance, 3D curvature and hydrodynamic efficiency which gives good lockup in the water but is still clean on entry and exit. Croker blades have been known for cleanliness and these new blades take it one step further.

Note: This blade is only available on the S39 Series of Arrow Shafts and are in limited supply.

SCULLING Sleeves

MARK 3 ASYMMETRIC (MK3)The MK3 is a major upgrade to the MK1 symmetrical sleeve and is held together with plastic interlocking clips. This double ended sleeve performs better because it only has two flat surfaces.

The asymmetric design reduces the distance between the shaft and the swivel face. It is more stable square or feathered and positive in its movement, squaring and feathering. This asymmetric design is not recommended for use with the Magik or Martinoli swivels as these swivels produce excessive wear on the sleeves.

Fits: S2, S3, S4, S7 and S39 Arrow shafts

MARK 1 SYMMETRICAL (MK1)The MK1 sculling sleeve comes in two parts, the sleeve body and the clip (back). The inboard measurements are calibrated on the back of the clip.

The sculling clips can be replaced as required without removing the sleeve.

SWEEP HandlesWe have designed our rowing handles with comfort and ease of use as our highest priority.

Selecting a handle that is correct for you is necessary to achieve the best performance. A handle that is too small will cause trouble

in the rough water and may turn in the rowers hand uncontrollably.

A handle that is too big will fatigue the rower’s forearms and also result in excessive wrist movement feathering the oar.

SEAT Tops

Carbon seat tops are the latest computer generated product to be released by Croker Oars USA. These ergonomic seat tops are functional, elegant and gender specific.

For the first time, carbon seats are available to suit female rowers. Women generally have wider pelvic bones than men.

Men’s and women’s seats are differentiated by the distance between the seat holes or depressions. The men’s seats have hole centres of 120mm or 130mm and the women’s seats have hole centres of 160mm. This will suit most rowers.

Small Boat Seats are 300mm wide (mens & womens), to fit most single sculls, this width may be an issue with older boats with shoulders.

Big Boat Seats are 330mm wide (men & womens), to fit doubles, pairs, quads, fours and eights. Some large single sculls may also accept a big boat seat. Contact us if you are unsure for further information.

They are designed, machined and manufactured in-house by Croker Oars. The seat tops are infused by the same advanced VARTM (Vacuum assisted resin transfer moulding) process used to manufacture our oar blades. These seats are compatible with most ball bearing wheel systems.

We are continuing to do extensive research around the world to develop a seat range to make your row more comfortable.

Croker Oars USA has the Seat Tops available to try at most major regattas.
