New RIB user - advice please

I'm considering the purchase of a 5-6m RIB for skiing/ringos and generally messing about with the kids - probably always in light conditions and longest trip probably cross-Solent

I own a 31' motor cruiser and have owned a 21' inboard sports boat so I'm comfortable with boat handling in a variety of conditions.

I am considering an Apex 19 with 90hp Mercury 4-stroke and a Zodiac Explorer 6m with 70hp Tohatsu 2-stroke. I'd welcome any advice particularly on the following aspects:

- dryness of ride
- fuel economy
- adequacy of engine size for skiing (I'm 12.5 stone) with (say) 3-4 up plus skier?
- engine reliability/ease and cost of service and repair
- hull/tube reliability

Thanks in advance

Hi,

Let me be the first to welcome you to RIBnet!

I too migrated from a ski / sports boat a while back and have not regreted it - so much more you can do with a RIB!

I can't comment on either of the boats but what i can say is that the two engines you list could not be more different...

Merc 4-stroke - excellent, modern and economical

Tohatsu 2-stroke - usualy older carb. technology which DRINK petrol (although i beleive they have a few newer technology engines in the range now)

I would go for the 90 4-stroke any day, it'll be more economical by far than a 70 2-stroke and more powerfull too. Some people claim a 4-stroke is not as good for skiing as a 2-stroke (inital grunt is less) but the 20 extra HP will make up for this.

As for power i can pull 2 skiers with my set-up (old-skool 2-stroke 130) but have skied off a RIB with a 40HP so i reckon 3-4 people plus skier will be OK with a 90 4-stroke. I would say 70 2-stroke would be slightly underpowered with that number of people in the boat.

Hope that helps a bit, i'm sure there are far more useful comments to come...

I had assumed these boats were new, but you're lack of knowledge of the boat would suggest they may be 2nd hand?

Never heard of Apex, worth checking this site (there is some info on manufacturers somewhere) and the RibInternational magazine website has archives of tests and links to some manufacturers.

One further peice of info i just thought of i do use a much smaller prop for sking than 'cruising' since i like to get higher top speed when cruising!

UPDATED

Plenty of hits in google

http://www.inflatableboats.net/apex.htm

Looks like what the purist RIBsters would call a fair-weather RIB though, bench seating etc. although the site does claim to be a deep-V.

Reccomended HP for the 19 looks like 115 with a maximum of 130, which seams quite high.

If thre boat is 2nd hand be sure to get a sea trial.

Hi and welcome

Their are many ribs in this range. I would always recommend getting out on the water in the boat before you consider buying. Are you considering the boats new or second hand and what would your budget look like. All of these factors determine what boat to get. If i was buying a 6m boat to ski with I would go for something with a new tec 2 stroke. Their are loads of threads on here discussing the different engines and manufacturers. I would prob get a small optimax 135 or maybe a ficht 115. The 2 stroke will give a more even amount of power through the range and with a really talky prop will put a crown with no problem at all. This would however bring down you top speed by several knots.

Have fun looking and If you have any questions just ask!

They're both secondhand. You can see pictures of these very boats at www.boatsandoutboards.co.uk !

Apex RIBs seem to be fairly popular in the US, and are designed for the sort of use you have in mind. They have a deep V at the bow which reduces rapidly to a moderate V at the transom. They should be reasonably quick and economical. Although this boat could take a motor bigger than 90hp you would probably be OK.

The Zodiac is likely to be a better sea boat, and is a bit bigger. I think you would probably be better off with a bigger engine though. I personally think that Tohatsu engines are fine, although they are certainly not cutting edge trchnology. The Zodiac has a proper console and jockey seats which you would probably come to appreciate even if you're not planning to go out in the rough.

Good luck!
John

Afternoon and welcome to Ribnet.

I personally have never heard of Apex ribs. I would aim for a small ish tornado 5 or 6 mtr. They are well built good sea boats and will do you nicely,

Julian

Hi
I have just been through a similar process of finding my own Rib, It took about four months to find the right Rib to meet my needs.

I bought a Humber Rib excellent Sea keeping & Handling, ride can be a little wet, although probly down to in-experience rather than boat design.

I run a 90Hp 2Stroke with a 13.25 X 20" good pulling power, I am learning to wake board from it. Burn 2/3 gallons Hour when playing hard.

I think the build quality is sound with very durable hull.

My only advice is to look carefully ask lots of questions.

All Ribster who use this forum always have something to say! be it good, bad or indifferent.

Happy hunting

Good advice AY, I like the Humber as a Open offshore Rib as it represents good value for money,it has the Beam and is a good Sea boat.

My advice withought getting into a load of upset is, If your going offshore get RCD cat B hull.

Engine ? Watch out for proposed emmisions regs.

Then enjoy it.

Given the above statements cleary sends out a message that you want this boat to be a fun boat ( and why not!) and considering you are towing water toys, Then I am not sure that dryness of ride and fuel economy are big issues to you.

- adequacy of engine size for skiing (I'm 12.5 stone) with (say) 3-4 up plus skier?
Thats really important and you have gotta have a grunty 2 stroke The snap is so much better from a two stroke. I own three engines 2 two strokes and a 4 stroke. A Yamaha, A Mariner Optimax and a Honda. I think the best made engine by far is the the Yamaha 70 Betol. The Mariner 150 Optimax is a superb power plant but backed up by an appaling distributor Barrus. ( I have been waiting six months for new starter motor)

The 4 stroke is heavy as most of them are and this wont help you reach your goals.

Servicing is readily availanle in the Solent area on any make of Outboard. Fairweather Marine are well reckoned, SAL in Lymington, Burseldon Outboards are pretty good and theres a couple of good mobile guys out there also.

In my opinion you should stick with Yamaha Merc/Mariner or Honda, it will also help come resale time

- hull/tube reliability
This is so important and for this reason I think you are lookiing at the wrong boats. Remember the sea is never your friend and can turn nasty very quickly. Stick to Ribtec, Ribcraft, Avon (yummy), Humber

If you are getting skiers clambering over the tubes you need to look at reinforcing strips/patches. Small Ribcrafts have an enviable reputation


Pete7 has a Superb Ribtec 6 mtr for sale, there are plenty of Searider 5.4 around and if you want one that looks nice then I believe you can pick up an Avon adventurer 5.6 with a 115 engine for around 10k.
