5m rib, 60hp..2 stroke or 4 stroke?

[Gray]

I've been looking around for my 1st boat and the 5m mark looks good for me. Ive seen two boats, both just under 5m, one with a 60 2 stroke and one with a 60 4 stroke. Whats going to be the main differences between the two i.e. performance and fuel usuage etc?
Thanks!

Hi

Depending on the rib about .5 litre per mile on the four stroke and 1 litre per mile on the 2 stroke (unless direct injection), in my experiance.

On a 5m Humber with 60hp Four Stroke we were getting about 35 knots, which seems very fast in a little boat.

One is a ribcraft and one is a tornado. I personally only have experience on a tornado and am under the impression their deep v makes for a soft ride. However ribcraft seem to me to be the boat of the moment for that size in terms of structural reliability. Any thoughts?

Both boats are getting 35 knots which is plenty.

What about a nice new humber -

2006 Humber 5m - 60hp Four Stroke - £9,995

The portsmouth uni rib is a 4.8 ribcraft with 60hp mariner 4 stroke. It's a very well built, stable and fast little boat.....

Jono...nice looking humber, a little above my price range im afraid but thanks anyway!

Tim, the ribcraft, whats it like when it gets a bit lumpy in the solent. Is it wet and dry and does it slam much....

For a 4.8m, it's unbelievably dry! She is without a doubt the best sub 5m boat I have ever been on.

Given the hull shape, she handles seas well - however she is fairly light, so does get a little twitchy at high speed (I've had her at 37kts with a 60hp 4smoke bigfoot). Build quality is superb.

If I am ever fortunate enough to be buying new - Ribcraft are definitely top of my list!

You'd be more than welcome to a spin in the Uni boat if you're ever down this way.

I would definitely go for the 4-stroke. 2-stroke technology in the range around 60HP is still pretty basic.

You can expect to get around 30-40% better fuel economy with a 4-stroke depending on how hard you push the engine (assuming a carb 2-stroke not an Evinrude Etec, Nissan TLDI etc). Performance will be pretty similar between the two.

thanks for the input people...

Jimbo do you know what year the uni's boat was made and how well are the tubes etc fairing up to being used by a university, Soton Institutes boat always seemed to look fairly worn out. Thanks for the offer by the way ill pm you about it.
