The Swell Shark is a seat and rail system allows dinghy sailing boats to be adapted for individuals with limb mobility limitations improving the usability of the boats while improving their overall safety.
This design innovation addresses the problem of no affordable intermediate adaptive boat options for children by allowing any existing dinghy class to become inclusive.

“(Sailing) has allowed me to, and the more I can get out and meet other people, like minded people, and it’s quite a good community, the sailing community, and it’s very healthy for me.”

Sailing was used as a case study as it is one of the most inclusive sports for physical disabilities allowing participation for a range of mobility levels including quadriplegia. Research shows that the exposure to blue spaces and the feeling of independence that can be found in sailing is beneficial to individuals with a disability. Despite the therapeutic and inclusive opportunities for children, sailing has been removed from the Paralympics due to a lack of participation internationally and is low on the list of adaptable sports in popularity and children rarely continue with the sport past the learn to sail phase.

The combined results from the interview and survey data confirmed some of the benefits barriers and facilitators revealed in the background information while revealing new considerations. The survey data revealed that parents are the main facilitators for children’s participation in sport with their main concerns including cost, staff trustworthiness and time constraints. Adaptive sailing has a variety of barriers that prevent initial and continued participation of children with limb mobility issues mainly centred around overall equipment costs and availability.

Swell Shark components are comprised of durable, marine grade materials such as stainless steel and ASL plastic (see BOM download for detailed material and manufacturing processes).
Wheels allow the user to slide along the rail system, with gravity keeping them vertical, and the widened foot base prevents the travellers from bouncing out of the track. By reducing the effect of waves and rocking, it provides them with more stability and feelings of security.
While weighted centreboards may reduce the likelihood of standard dinghies capsizing, it is still possible. The rail system is open-ended to allow the chair and travellers to slide over the side, allowing them into the water vertically so their life jacket can be effective and they can be easily craned out of the water.
There are two fail-safes to ensure the user is released from the boat in a capsize in the event that the chair does not leave the rail system: breakaway buckles to the lap straps of the seat and a 60-degree tilt switch release for the straps.
Through the 3D printing manufacturing process, chair colours can be customized to suit any child’s combination preference.
