Fastest 5m RIB

[Low Flyer]

Have no idea on the speed thing and wondering what is the quickest 5 to 5.5m RIB ?

[willk]

I think this is it:

Linky

Sarcasm aside , A Ribtec 5.3 with the right 90hp OB will do a genuine 40knts. I know this, 'coz an irritating tw@t passed me in one doing 40knts.

Hadd's Ribcraft 545 can Shift a Bit!
(I30 E-tec one up 46knts+)

Tohatsu one design was a pretty quick hull. Not too sure if they did a 5m version though.

Thing is, why do you want to know about top speed? Surely the best sea keeping ability will get the fastest journey time on a normal cruise.

My jet ski will do 52kts and will go from 0 to 30kts in two seconds. And it's only 3.56m long.

Not sure if that qualifies,without discrimination it's not really a RIB. Although I agree it is quick.

A fair comment!

I must be getting old but here's my logic. Top speed is usually limited to a given sea condition verses a given boat length/design/power. There aren't many days that we get mirror calm waters in order to exploit top speed, the trouble with setting your boat for high speed running usually means compromising your normal running set-up.

Very true,I'm fortunate enough to run two boats. 8.6 m for cruising and rougher stuff and 5m for shits and giggles.

Well I think the thing to do is to experiment and do something others haven't. I often thought what a RIB would go like with a small block V8 running a cleaver prop

Oh yea, I remember that........

Every day!

What was "the right 90hp OB" ?

Think he was meaning any nicely running 90, probably a 2 stroke because of weight. In this case it was a mid 90's Evinrude Ocean Pro.
The Ribtec is a nice hull, deep V but quite narrow.

Hence, being quick for it's length.

Aye .. Ive had a lady complain about that..should have got me a discount

[Boatnomad]

40knts for a 5.3,impressive

[CJL]

I nearly bought this 5.5m with a 225hp 2 stroke......

Must have been a real speed machine!
