We operate a Humber 5.5m Assault with a Suzuki 70hp 4 stroke, it does carry 6 divers with single cylinders & the Cox. We did have problems getting up on the plain but after down sizing the prop it is now going well. We had to go with this small combination for a number of reasons.
1. The boat had to fit inside an old lorry container, without deflating it (we don’t want to spend half hour pumping it up at 6:30am) so it couldn’t be too wide.
2. The boat has to be small & light enough to tow behind an average saloon car, no one in our club has a 4X4
3. It had to be a cheap as possible (I think all clubs can relate to this one)
Needless to say with it being a small boat it is very cosy, with not a lot of room to kit up but we manage.
If you have the space to store a larger boat & the vehicles to tow it & wanting it to carry 8 divers I would go for as large as you can afford. The Humber 5.5m is very good for 4 divers & a Cox but with 6 it’s on the limit.
I have been at a few dive sites where there have been Tornado RIB’s they are wider & sit a lot higher in the water than our little Humber, and I have seen the 6.5m Tornado with 8 divers & a Cox on board & they seem to have a lot more room then we have.
XS-Ribs started coming onto the market just after we ordered the Humber, their price looks good & the hull looks the same as the Tornado so I would imagine they would handle the same with as much space only cheaper.
If these were available earlier we may have ended up with one of these instead of the Humber, although we would probably have to half deflate it to get it in the container.
