Cadet and PARA oars

Swift is producing oars for use with our Cadet and Cadet Mini boats or by PARA rowers, These are manufactured with purpose built tooling, so are correctly sized, not just “cut down” versions of normal scull oars.

Handles and grips

We offer 3 grip sizes, on 2 sizes of handle.
Handle size Small Medium Medium
Color code Red Orange Purple
Grip diameter 32mm 35mm 37mm

 
The external diameter of the handle is cut by CNC machine to fit perfectly inside the shaft, where it is securely held.
 
 

Length adjustment

Simply loosening 2 screws allows for quick and easy length adjustment,of up to 12cm. All handles have overall length engraved, so avoiding the need to measure length each time they are adjusted.

 

Grades of shaft construction

Please note that even with 12cm handle adjustment range, because of reduced overall length, oars become light and also very stiff. We therefore do not offer HP grade.

CP - Club Performance

As with the regular length oars, the CP oar shafts are 70% carbon, and blades are made from carbon, with PVC foam core, and white gel coat finish. Weight and stiffness vary with length, so please see chart below for details.

Rec - Recreational

As with the regular length oars, the Rec oar shafts are 40% carbon, and blades are made from carbon & fiberglass, with PVC foam core, and light grey polyurethane paint finish. Weight and stiffness vary with length, so please see chart below for details.

  CP REC
Total weight – (per piece) - Long 1.42±0.2kg 1.47±0.2kg
Total weight – kg (per piece) - Medium 1.36±0.2kg 1.41±0.2kg
Total weight – kg (per piece) - Short 1.34±0.2kg 1.39±0.2kg
Maximum variation per pair - kg 20g 30g
Shaft stiffness – cm - Long 35mm 40mm
Shaft stiffness – cm - Medium 28mm 34mm
Shaft stiffness – cm - Short 24mm 28mm
Maximum variation per pair - cm 2mm 2m
Stiffness is measured the same way as for regular oars, with the weight suspended from at the connection point of shaft and blade.

Cadet versus PARA scull oars

There are actually 2 ranges of oars, each with 3 different lengths. The difference between the 2 ranges is the position of the sleeve.

Cadet oars

The sleeve is positioned so that when used in Swift Cadets or Cadet Minis, small rowers can achieve the same length of rowing stroke and similar gearing/loading, as taller people in bigger singles.
These oars can also be good for many PARA rowers, with longer inboards and shorter outboards compared to the PARA oars.

There are 3 lengths of Cadet scull oars:
 

  A2 blade A3 blade
Long - Length 268-280 273-285
Long Cadet - Outboard 184-199 189-204
Medium - Length 256-268 261-273
Medium Cadet - Outboard 176-191 181-196
Short - Length 244-256 249-261
Short Cadet - Outboard 166-181 171-186
Length adjustment 12 12

PARA oars

The sleeve is positioned so that they are only useful for PARA rowing, where very heavy gearing/loading is wanted, such as with internationally competitive PARA rowers.

 

  A2
Long - Length 268-280
Long PARA - Outboard 193-208
Medium - Length 256-268
Medium PARA - Outboard 190-205
Short - Length 244-256
Short PARA - Outboard 181-196
Length adjustment 12

These oars are not available with the A3 blade.

Oar covers are available and can be ordered from our website or by contacting us directly.

 

ENGELLİ / PARA rigging guide

The following is our guide to choosing scull oars and deciding rigging for PARA rowers, and will be suitable for most PARA rowers.

Rowers with a very short range of movement, such as Arms & Shoulders rowers, should have narrow rigger spans, to help achieve a longer rowing stroke/arc. Range of movement is also determined by height, arm length and flexibility.
Most PARA rowers have little or no overlap (of handles).
The Outboard measurement, which is simply the total oar length minus inboard, when divided by inboard determines the level of gearing/loading (that is, how heavy the stroke is/feels).

For example, if span is 140cm, inboard will be around 70cm.
With oars that are 260cm long, outboard = 190cm, so gearing = 190/70 = 2.7
With oars that are 245cm long, outboard = 175cm, so gearing = 175/70 = 2.5

Stronger and more experienced rowers can have higher gearing and beginners and weaker rowers need lower gearing to maximize performance and reduce injury.

  Span (cm) Inboard Length (cm) Outboard (cm) Gearing
AS beginner 130-140 About ½ of span 230-250 160-185 2.3-2.7
AS 125-140 About ½ of span 240-270 170-200 2.5-3.2
TA beginner 140-155 About ½ of span 245-270 165-190 2.3-2.5
TA 135-155 About ½ of span 260-285 180-205 2.4-2.8
