Moving around the site is an important consideration. Mud, sand, soft or slippery surfaces are difficult for the less agile. Rough terrain is hazardous for people with visual impairment. Moving around the boat must be considered. See Chapter 6 - Adapting Boats.
Safety is a concern with disabled sailors as it is with others.
A lack of balance, mobility or agility may require extra support, seats, harnesses and lifejackets. Impaired vision may lead to stumbling over an unseen obstruction. Impaired hearing could mean failure to hear a shouted warning. The toilet needs of a paralysed person or an inability to sit for long periods may influence the length of a voyage. It is important to check that everyone has adequate food, drink, protective clothing and drugs for the time afloat.
