CLASS ASSOCIATION.... https://www.sonar.org/
My judgment is ..... What I nice boat to sail... easily adapted for most disabilities but its sheer size and fixed keel are against it.
8/10 - As a boat for all types of disabilities - although the manufacturer does not offer options for disabled people the sheer size of the Sonar makes it easy to modify for any type of disability - I only lose the two points because you have to do it yourself.
10/10 - As a boat for experienced disabled sailors - very good it has something for everyone.
8/10 - As a training boat - it is very good but you have to have the mods to make it good for everyone.
9/10 - Ease of rigging - not difficult but it looses a point because I cant do it myself.
1/10 - Ease of transport and launching - this is a big boat, it can be moved and trailered but it needs some work.
8/10 - Controls - very good but you may need strength or power assistance.
10/10 - Quality of fittings and build - very good.
8/10 - Getting in and out - very easy but its space works against it.
10/10 - Sailing qualities - very good.
10/10 - As a club boat - very good.
SCORES 82/100 ON THE BOAT CHART
There are many pro's and con's with the Sonar, its is a very good sailing boat, performs well and is a design for able-bodied people that has been adopted for use by disabled people and allows good integration of abilities. It needs a crew of 2 to 5 people, usually 3 in disabled competition, and this is good or bad depending on your view.
Would I sail one today if offered the chance?.............. yes please, nice boat.
