Notes

Shoal draft fin: 1.2m/3.9'
Bilge keel: 1.1m/3.61'
When first introduced, this model was promoted as being 'unsinkable'. It was built with a number of strategically placed cavities filled with foam throughout the interior. To prove the claim, a number of tests were conducted, where the boat was completely flooded, after which it not only remained afloat, but still maneuverable.
