I had a 5.3m from new for four years till I could afford to offload it. I really wouldn't recommend one if sea keeping or a good ride is a concern.
I bought another new Humber to replace it so I am not manufacturer bashing and have no axe to grind. Mine went all over the west coast to some fairly inhospitable places and rough weather but I never did rate the hull or boat.
I would recommend trying one before buying but as they say. You pays yer money and takes yer choice but an Assault would never again be one of mine.

See pics of transoms. Assault tubes are attached much lower on the hull than the destroyer all the way along meaning the hull is recessed in between the tubes making what is already a fairly shallow hull even shallower.
Rough chop and weather is extremely hard in an Assault on your back and legs. After a few long passages I stopped contemplating any more in anything bar a flat calm.
Also due to the design the tubes extend quite far back from the transom meaning you lose about 1ft of effective hull length and also 1ft of interior space compared to just about any RIB of similiar overall length.
The Destroyer pic shows tubes attached much higher and the difference this makes attached a reasonably deep V hull. See also the tube extensions compared to the Asault version

humber assault pics

Hi
Blue boat is 2010 assault 5m,yellow boat is 2001 similar,long overhang on rear sponsons gives lots of support for a heavy engine but seems to cause more cavitation especially when training new drivers (hard turns,accelerating around slaloms etc)
Would hardly call this a shallow v though?

V-wise, it looks about the same as my Destroyer at the stern but I expect it is the low slung tubes that screw up the ride because the waves are effectively whacking into a flat surface. I don't think the bow V is as sharp as the Destroyer either.

I currently have a Destroyer and had an Assault. Believe me when I tell you from practical experience that the destroyer is considerably more "deep V".
The ride on the Assault is awful compared to it.
I always assumed the sponson extensions are for two reasons, to protect the outboard when on the water and backing into a garage and also to make the bow stay down, again for inexperienced cox's.
The difference in on water handling is also marked. An Assault will skip sideways flat on hard turns as not enough hull is in contact with the water. Destroyers will lean in and turn 180 degrees at 30knots within two boat lengths, or at least mine will
Other deep hulls will do this just as well or better.
The story of how I ended up buying an Assault has been recounted on here before but basically I ordered it by phone due to my location. I asked if it was the replacement model for the Attaque and when told it was I ordered it. When I turned up at the factory I was horrified to find what it actually was but by then it was too late. It was the replacement in their "model range" for the Attaque but was nothing like it in form.
Right question but not the right answer and from the day I bought it I was planning to replace it.
The Assault is really a cheap small rib for pottering around on lakes, inshore and for sailing club safety boat use where it won't be exposed to much rough weather. It is cheap, fits in a garage and it easily handled.

When I ordered the assault they were doing a similar discount on all models,don't know if they still are though (and VAT was only 15% then)
Mind it was the depths of winter, January seems the best time to buy anything boaty ,first of all they wonder why you want it then at all ,next they offer a great price when they realise you are serious!

Possibly, although I've noticed that a certain otherwise busy manufacturer seems to have a wee lull towards the Autumn (Aug/Sept). I'm guessing, but I think it's because the leisure market has their "boat for the summer" and a lot of the casual commercial guys don't want a late season completion (making their boat a year older than necessary).
