Measuring your seat hight helps you compare different seats and systems.
How to measure seat height.
Place a straight edge across the coaming above the seat and measure down into the lowest part of the seat bowl, along the centre line.
Remove the seat and measure to the hull.
Subtract one measurement from the other and you have the seat height including any foam and material thickness. You can now compare seats between similar hulled boats. Boats vary in draft (depth in the water) this can be as much as 35mm between flatter and narrower hull sections. Your seat height and stability are relevant to the water level.
A. Simply by undoing the 4 thumb nuts and selecting another position.
Platform Seat Pitch
Q. What benefit do I get from pitch change?
A. Changing the seat pitch changes your pelvic tilt, this can reduce lower disc compression (increased pitch) Gees seats are pitched at 15, helping the paddler to get increased performance as well as comfort. Other manufactures seats are pitched from negative to five meaning some of the seats are leaning backwards.
Q. How do I change the seat pitch?
A. As for height change but select uneven holes, higher back or front by 1 position. (Not available on lowest setting)
Q. I feel as if I am sitting on the back of my seat.
A. Try changing the seat pitch. Knees to high so leg drive pushes you over the seat back. Insufficient push with the upper shoulder resulting in weak body rotation (seek technical help).
The Low seat has a 15mm lower paddling position and is perfect for the paddler that requires more stability. The seat has 2 height settings and no change of pitch. The seat is located and held onto the boat platform by a front slide track and two rear bolt system. With forward and backward adjustment of 143mm at 7.5mm increments gives fine adjustment for leg positioning, allows you to achieve your optimum paddling position. The seat will easily transfer between boats with the same platform fitting. Changes to the seat set up are quick and easy, even when at the waters edge (no need for a tool kit).
The 147 low seat is suitable for the less stable paddler, used by club starter and novice DW paddlers.
There is a higher seat option which has a 15mm higher paddling position and 5 height adjustments. Please see Platform Seat 147 for details.
The 147 seat size platforms are used by Kirton Kayaks and Marsport.
The seat has 5 height and 3 pitch settings and is ideal for the paddler who wants a precision technical setup. The seat is located and held onto the boat platform by a front slide track and two rear bolt system. With forward and backward adjustment of 143mm at 7.5mm increments gives fine adjustment for leg positioning, allows you to achieve your optimum paddling position. The seat will easily transfer between boats with the same platform fitting. Changes to the seat set up are quick and easy (no need for a tool kit).
Continental made boats usually have a wide platform and require a wider seat sub frame, for use in Nelo, Zastera, Vajda, etc. The aluminium seat supports are custom-made for each make of boat, prices on request.

The 147 seat size platforms are used by Kirton Kayaks and Marsport.
Gees seat platforms are designed with a slide and rear bolt system; the seat is held securely even when the boat is upside down.
The seat adjustment is over 143mm at 7.5mm increments.
Platforms are available from 175mm to 255mm wide for the 147 seats and 215mm to 255mm for the 183 seats. Wider widths are available for larger K2 and K4 kayaks
The choice of platform width is important as the wider the platform the higher the seat. The seat height position is relevant to the water and not the height within the boat. Kayaks vary in draft/displacement by 35mm from the stable racing kayaks to the modern narrow hull sections.
K2 platforms are usually wider and tapered to maintain a level position, custom made for each model of boat and height.
Platforms are easily installed in craft without them (see fitting information).
Helpful hints for installing platforms:
Locate platform in front to back position.
Level boat then level platform.
Apply masking tape to hull around platform glue area.
Sand hull to expose fibres and clean surface.
Apply masking tape to top edge of platform.
Apply glue, work into both surfaces then apply more.
Position platform.
Place 5kg of weight on the platform to hold it in position, use a flat board along the centre of the platform to spread the weight.
Check level.
Tidy up glue line.
Remove masking tape allow glue to harden over night.
Recommended glue
Flexible Polyurethane
Soudaflex 40FC Polyurethane Adhesive
Sikaflex – 291i marine adhesive / sealant
(other makes available)
Seat adjustment:
When adjusting position and heights of the seat it might be necessary to
slacken thumb nuts to align bolts with holes.
Do not over tighten thumb nuts as this will make them much harder to undo.
