Advice needed - RIB

Hey Guys,

Im looking at purchasing an RIB for the sole purpose of scuba diving and / or spearing (for sheltered and calm water) and was wondering if anyone had any advise on what I should be looking for?

The specific one I'm looking at is a 4 metre Callegari Alcione America that comes with a 25 hp Johnson outboard. The guy who's selling it is unsure of its age but it has a Thames River Authority Compliance plate on the transom dating it to 77 (8 years older than me lol). The glue appears to be holding and doesn't have any holes or leaks.

Does anyone actively dive from an RIB and has any advice regarding doing so, or anyone have any reviews of this type of RIB? Is its age a potential issue? The motor is a lot newer than the boat, and apparently runs quite well (I know the guy selling it so i trust him on that).

Any advice welcome.

I would suggest fabric (and adhesives) have moved forward a long way in the last 30 years and whats more these, at that age, may well be coming to the end of their lives.

If it is cheap enough and you get a couple of years out of it, then it might be worthwhile.

A 4 metre boat is pretty small to carry say 4 divers (especially a RIB where the tubes eat up floorspace) and 4 is a pair tending the boat while a pair dive. As someone who has dived with an empty boat above many times I am not going to tell you not to do it but I really think it adds a significant risk factor.

I'd think it is small also for tackling the southern ocean but its been many years since I dived in Victoria so perhaps some local advice is needed.

G'day,

You don't see too many RIBs out and about in your area, and there's probably a good reason for that.

A few years ago I dived a few times out of Rye from a RIB. It was about the same size as the one you've mentioned. It had a bigger motor that the one you mentioned. It was severely underpowered.

When loaded up with some divers and their gear I would suspect you'd be very limited as to the sites you could get to if the RIB you're looking at is underpowered. But others on here will know much more about this than me.

For some information about how my dive boat is setup, please see http://www.borrett.id.au/interests/diveboat.htm

Best regards, Lloyd Borrett.

And what is that good reason?

I own and regularly dive out of a 4.8m ex military RIB. It is so old I couldnt even take a guess but it holds together well and I havent come across any boat yet I feel safer in during large seas and stroms. I usually dive 3 or 4 people out of it and it is spacious enough even with a large centre console taking up 60% of the deck space. RBs, stages and twins often or just 2 singles each. The only downside of the centre console or tiller steer RIBs is its usually a wet ride so its suits on before departure.

I run a 40Hp and its plenty big enough for what I do and pushes me along at about 25Kts. Cant comment on a 4m as it could also be narrower than mine but if its at the right price then its probably worth it. Best thing about the RIBs is their stability at rest and low fuel consumption. If you have any specific questions about RIBs just pm me or reply on here, I love my RIB and so does everyone else who has dived from it.

I have a RIB in the shed I sometimes dive out of (from Barwon Heads). It's 4.2m with a 25hp 2 stroke. I wouldn't put any more than two divers in it, and then it's really only good for shortish trips, as it's bouncy (compared to my catamaran) and wet.

Having said that, it's hugely more versatile as I can launch it at any beach, and easily get through the surf. Great for diving the west coast between Torquay and Apollo bay where there are not really any ramps suitable for bigger boats.

It is also quite old and had patches on its patches, but still holds air for weeks.

It tows behind the car like it isn't there.

For a while I thought about selling it, but now I'm happy to keep it in the shed for the occasional squirt. Even attached the surfboard to it the other day and surfed some of the difficult to access breaks!

Oh, another thing worth considering is the electrics. Mine has a battery which gets charged by the engine allowing me to run a bilge pump and nav lights, but more importantly a sounder and GPS. Finding new dive sites without a sounder isn't easy... Oh, and a radio also comes in handy!

In conclusion, it really depends on the sort of diving you want to do with it, and how many friends you have!

I seem to have more friends in summer than in winter.... :-(

If it's cheap, go for it!

Cheers,

Bart

I have a RIB, mines 6m with a 115hp eTec on the back.
For a private boat I cant think of anything I would prefer to own, rock solid platform for diving for up to 5 divers for locals and usually 2 or 3 of us when we are heading over to Rotto about an 80km round trip.

We purchased the OEM hulls direct from China and shipped them over in a container, fitted them out here in Perth, in doing so we saved well over $15k

Thanks for the feedback guys. Much appreciated.

Its pretty cheap. Asking price is 2k with a trailer (7 years old), which for me at the moment is the right price. The other consideration I have is my car at the moment is not really up to the task of towing anything too heavy (1.2 tonne braked capacity), but that's what I get for buying a sports car.

I dont imagine I would have any more than two divers, plus maybe a driver / spotter for when I actually take it out, or maybe 3 freedivers + a driver, so weight wont be too much of an issue. The guy I'm buying it off recons that hes had up to 4 (scuba) divers in it - but discouraged me from doing the same.

Nautilus - that's exactly the sort of thing i would be using it for - great ocean road "theres a nice spot, lets put in" style diving - which is why I was looking for an RIB in the first place. Other things like taking it over to SA and launching from beaches in places like robe or port macdonall chasing crays means I can get it into otherwise inaccesable beaches (and also not using too much extra fuel getting it there!).

I would ofcourse be adding a depth sounder / GPS / marine radio to the mix so I would have to figure out how to wire it to the motor (if it even has an alternator) but that's a problem for future me to solve.

Ill be sure to post if / when I get it and let you know how i go with it. Its going to be my first boat (I've handled boats before, just never owned one) and I want to be as versatile as possible :) - at least for now.

Oh, and Chriso - Checked out that site.

How much did it cost you to purchase and ship the OEM hull over from china (if you don't mind me asking). Those look like some pretty sweet boats...

Also, how much was the total cost of getting it seaworthy?(eg. Motor / getting it fitted / putting in the extra bits, etc.).

Pricing off the top of my head
$15k for the hull landed in Perth
$13k for the eTec 115
$3k for a Dunbier dual axel trailer
$3k for electronics
So on the water for around $34k

Same hull with a 90hp Suzuki and single axle trailer sells down the road for $50k+

Hey mate,

I used to have a zodiac futura 4.2m, I ended up wishing I had bought a rigid hull, I used to get hammered in chop and basically had to go tortoise speed, a V hull would have helped. The dimensions I imagine would be similar. I had a 25hp engine and got up and going with 3 divers and 6 tanks inside, but only inside Sydney harbour, outside it was a usually a bit too choppy except for on a perfect day.

One thing, organisation within such a small boat can make the difference between having a good or stressful dive.
