Delta's D-Class

This article got me thinking:

Maritime Journal | Delta's 'D-class'

Is there a specific reason that the RNLI still use an inflatable for inshore rescue work rather than a RIB, as Delta have built? I would expect far better performance from a small RIB. With modern materials, the bottom should take more punishment too.

There are a few RIBs like this in use with independent lifeboat organisations: http://www.rib.net/forum/f16/sneak-preview-63957.html

The RNLI like to do their own thing.

Interesting, thanks. How does the performance of that boat compare to the traditional D-class? Pros and cons of using a RIB for the role?
