Virus Rowboats - Manual



Yole Club and Class

There are three positions: fore (front) and aft (back) for double rowing and center position for single rowing.

Setting up for single or double:
Set the foot stretcher in the aluminum track tubes in relation to the rigger mounts. The rigger mounts are the 6 pair black or plastic mountings on the inside of the gunwale, three pair on the right side and 3 pair on the left side of the boat. The two pair in the center position are for single rowing and the pair fore and aft are for double rowing.

To start: lift one aluminum track tube out of the bracket at the stern (back) and insert the foot stretcher, counting 4 holes on the track (always) towards the stern. As a guide use the second (toward the stern) of the pair of the appropriate rigger mounts on either side. Center for single, fore and aft for double. When setting up for double it is easier to insert the foot stretcher for the bow. Use the same procedure and hole count. (image 1)

Make sure the center hole on the bottom of the track tube is aligned over the pin. Then snap the track tube back into its bracket.


To adjust the stretcher to your individual height, take rowing position in the boat, with both feet placed in foot stretcher and legs fully extended, place hands on grips (thumbs over the ends of grip), pull both oars toward your mid section (left hand over right). As you pull back, your thumbs should just graze your mid section without leaning excessively backward. If your thumbs are too far away or if you have little room between thumbs and mid section, adjust the foot stretcher and repeat the exercise.

Place the seat(s) on the tracks with Virus logo pointing toward the bow of the boat. (image 2)

Insert riggers into black rigger mount on the inside of the gunwale. Match color strips on riggers and on inside of gunwales. (image 3 and 4)

Virus foot bed installation


Virus sliding seat installation


TURBO II Classic
(sliding seat)

All equipment: seat and stretcher are packed with the rigger. The 4 bolts and washers to attach the rigger to the hull are in place where the rigger is to be set.


Attach the rigger to the hull with the bolts and washers. (image 5) Use a 13mm socket wrench. Set the seat on tracks with logo pointing toward the bow of the boat. To start: lift the aluminum tracks out of the brackets and insert the foot stretcher approximately 3 holes from the end (right under the rigger).

To adjust the foot stretcher to your height follow the exercise for the YOLE.


TURBO II WING and TURBO SKIFF SL(sliding rigger)

The sliding rigger is complete with carriage, wing and foot stretcher. The seat is attached to the track (TURBO II Wing) and a molded part of the hull (TURBO SKIFF SL).


The rigger carriage slides on the track. (image 6) The rigger wings are open and pointed toward the bow of the boat. Lift the track out of the brackets. The tracks enter between the upper and lower rollers in the carriage case. Reset the track into positions. Fasten the track in the brackets with the bolts/wing nuts, finger tight. (image 7)


  • Virus Sport Oars 280cm/110" for Yole Class and Yole Club: no assembly needed.                                                                
  • Virus Sport Oars 3m/118" for Turbo II and Skiff SL: no assembly needed. 
  • Dreher Carbon Oars 287cm/113" do require assembly, collars onto sleeves.


The collars are green for right (starboard side of the boat = rowers left hand) and red for left (portside side of boat = rowers right hand). The bolts/nuts on the collars need to be loosened. (image 8)Slide the collars, with the flat side towards the blade, over the sleeves. The correct inboard position of the collar on the sleeve, for an average load is 88cm/34 2/3". The measurement is to be taken from the end of the grip to the flat of the collar surface.


Options for adjustments: Aluminum Sport 3m and Dreher Carbon 287

To increase load: shorten inboard distance (collar to grip) for longer distance and more power.

To decrease load: lengthen inboard distance (collar to grip) for longer distance and less power. (image 9)

"Snap in" Oarlocks. The oars snap in/out at the narrowest part of the shaft, where shaft meets the blade. (image 10) The oars will sit firm and will not come out while rowing. To insert oars into oarlocks, point the oarlocks parallel to the hull, pointing to the stern of the boat.


Turbo II Classic, Wing and Skiff SL: The oarlocks are gated. To set the oars, open the gate, position oarlocks parallel to the hull pointing toward the stern of the boat. (image 11) Place the oar in the oarlock between oarlock and gunwale. Close the gate with the plastic nut, finger tight.

Adjusting the oarlocks: Oarlocks are set for cross over left hand over right. Setting can be adjusted if the rower prefers higher sitting oarlocks, yet should keep the same difference of washer of pin below and above for each oarlock.



Yole Class and Turbo II Skiff

The material fiberglass is delicate and at the same time durable and robust. The Yole Class and Skiff SL should be stored on boat slings (camp stools work very well). Place the slings approximately 1/3 from either end of the boat.

Seitech Dollies(models for Yole and Skiff SL) make for excellent boat storage. For extended storage lay the boats deck down on 2 x 4 covered with carpet or suitable material.


Rowing in saltwater: Rinse the boat down with fresh water after each row, concentrating on all movable parts. For lubrication of moveable parts (stainless steel rollers on seats and riggers) Silicon lubricant serves best. For shine, use regular boat cleaner and wax.

Yole Club and Turbo II Classic and Wing

The material is among the toughest and most robust. The boats are well constructed and do not need any special maintenance. Store Yole Club and Turbo II Classic and wing on boat slings (camp stools work very well). Place the slings approximately 1/3 from either end of the boat.

Seitech Dollies (models for Yole and Skiff SL) make for excellent boat storage. Otherwise, Polyethylene lends itself to most common types of storage.


Same as above for Fiberglass boats. For total cleaning use regular "soft scrub", in special cases the power washer works very well.


All oars should be hung, leaned upright close to wall or lay flat.
