Fastest small RIB option?

Lod · Today, 15:06

Hi there!

New here. Please enjoy my probably daft question which shall go as follows:

So I used to have a Warrior 175 with a 140 Suzuki, then I had a SIB for a year- a Boatworld Carno Pro 365 with a Tohatsu 20HP engine. Someone stole the engine and I ended up selling the boat, but I'm hoping to get set up again for the spring. The thing is, I loved the SIB and it went about 20 knots which is awesome, but it was useless as soon as there was any chop at all. I did like the portability of the SIB but I ended up keeping it on a trailer anyway, so I think I might as well get a RIB or maybe a FRIB?

My question is this - if we were to say RIB, what's my best option, staying as small as possible to get something much faster? I'd love to be able to bomb it over to the isle of Wight from Poole Harbour in 20 minutes. Something that goes 30+ knots easily? Maybe even 40? But I want to keep it as small as possible becasue I love hunting bass in extremely shallow water and big engines are bloody expensive. I realise I'm going to have a bigger engine and therefore a bigger boat but what do you guys think is the minimum to get some speed going?

Hello and welcome to the forum.

Don't get an Frib given your needs and experience with the SIB, they are likely to have a harder ride than many SIBs.

Sounds like a Searider SR4 with something like 40/50hp would suit you. Small but very capable for making the trip you mention.

Ok awesome, thanks, I'll take a look at it!

I agree with fenlander avoid the frib, worst of both worlds sr4 is the obvious choice but iirc ribcraft did a 3.6m rib & I think humber also did one. Avon did the supersport too which is smaller but if 4.2m & 50hp would suit, you would struggle to find better than the sr4. If you could manage larger then a 4.8m ribcraft would be a good option. Avoid the smaller "med style" boats which tend to be fairly shallow vee & often pvc tubes & not great build quality

My gut feel for this part of the brief:

Would be a ZapCat (other brands are available). It may not be a sensible suggestion, but you should give it at least a moments thought.

Thanks everyone. I've been looking into this - Forgive me, I'm really new to inflatables, but isn't the SR4 like, reaally old? From the 80s or something? Kind of hoping to find something a bit more modern. But then I don't know? Maybe a 40 year old RIB can still be amazing?

Careful, a lot of the people who post regularly on here are even older than the SR4 and don't consider themselves "really old"!

Yes, it is a "classic" design rather than very modern. As a general rule, over time RIBs have got bigger so the choice at the small end is limited with a lot of what is there being fancy yacht tenders or for popping from a med harbour to a beach not bouncing across waves. One feature that is almost unique to the SR4 is the "flooding hull". This means when you stop the boat sinks into the water and becomes a very stable platform - that will make it great for your fishing. It does mean it takes a bit longer to initially get on the plane as you have to wait for that to drain (some people sacrifice the stationary stability for better acceleration by blocking the hull up). It was a very successful design which lasted for decades because it was very good. There were two formats - one that looked link a 1980's car with "comfy" arm chair seats and one with a classic centre console. The latter still look reasonably OK if well maintained.

Hard not to echo the same - SR4 and a 40 or 50 2 smoke. Plenty of dogs about but many nicely restored ones too if you are patient.

You will struggle to find a new off the shelf boat that's all round as good as an sr4, although an old design they were still being sold until quite recently.
Imho build quality & hull designs have gone backwards in the small boat class, as already mentioned many are only good as tenders with fairly limited life. A nice late model sr4 is a hard to beat package.

Very interesting, cheers. The stability of the hull sounds like a bonus, but then having to wait for it to drain before getting up on the plane sounds like a drawback as I love to just fly off. When you say it takes longer, are you talking a few seconds or a few minutes? Cheers

Cheers. I'm assuming you mean 2 stroke? You would choose that over a 4 stroke? Just wondering why?

Your only talking seconds of difference in time to plane with the flooding hull & with 40hp+ you hardly notice the loss in acceleration. The two v 4 stroke argument is getting less of an issue as 4 strokes are getting lighter & are closely matched for grunt nowadays the extra range & improved fuel consumption makes a strong argument for a 4 stroke. I'd happily have either, but perhaps avoid very early 4 strokes

Thanks, good to know....
