Ribs too heavy for watersports??

14148 · 26 January 2006, 11:16

sorry for posting new thread still getting used to the system!After speaking to a sports boat dealer in the south west yesturday he suggested that ribs in general and my 7.5 cobra that i am looking to buy with a 250hp on theback.Said that the boat is heavy and will not have good enough acceleration for watersports such as mono sking.I did not agree with him was wondering if any one could help me confirm the truth behind this.Any help greatly recieved.Thanks

I used to have an Avon 620 with a DF140 Suzuki on the back and we never had a problem using it for Wakeboarding off the back of, even with 2/3 people on board. I appreciate you are getting a bigger Rib but then you will also have a much larger engine on the back.

Did he try and sell you a boat by any chance?

14148 · 26 January 2006, 11:39

yeah he was trying to. just wanted some clarafication that what he said is not true

Suck it and see I guess.... it'll be a lot cheaper buying a mono-ski and finding out you can't use it than buying a new boat.

There has a been a few threads on current ribs on the market, i have listed too below.
It is possible to ski behind a Cobra 7.5 and 225HP but I dont know about mono ski. If water sports are your primary factor I would look more into a sports rib such as a Solent/ Scorpion etc. Get the maximum HP it will take and you should have no problem with watersports. The propeller can be changed if you require more acceleration or top end etc.

This dealer is talking nonsense.

I have a 7.5m rib with 225hp motor, and I've towed not one but 2 (expert) mono skiers.

Not a problem at all.

donutsina911 · 26 January 2006, 13:35

ditto...our 7.8 with 200hpdi pulls my enormous arse up for mono ski-ing and wakeboarding without any problem..250 verado will be a piece of cake...

Roycruse wakeboards behind his 5.85 ribcraft with a 140 Suzuki and he's not small (20 stone to be exact but I wouldn't put that on a public forum)

i have ski'd many time behind a 6mtr northcraft with 135hp no probs ,,, guess i am in the 20 stone brkt also..and have seen 5mtr tornado with paracender on the a -frame well dodgy looking but worked none the less

Easy for him to say that it’s another matter whether it is true or not

What weight is of the Cobra when compared to the boat he is trying to sell

I think more of an issue would be hull shape, a deep V will take longer to get on the plane (and pull up skiers) than a shallow V

Craig C and his squad used to ski behind a Redbay 7.4 canopied RIB with an inboard 165hp Diesel

Andy
P.s and he's no lightweight

Towed 2 mono-skiers with a 5.8 Humber with 150hp Yam.
Same with 6.1 Tornado with twin Merc 90's
Same with 6.5 Hysucat twin 50's

Will tow four skiers with current set-up.

The problem you will have with some ribs is simply the height of the wake. For mono-skiing I have to really brace myself going across the wake. Wake-boarding is brilliant with current set-up! I do not think 'hole-shot' (as the yanks say) is the issue, rather the inherent deep V which is not ideal for skiing, you could do better with a flatter hull - IMO.

i ski and wakeboard fine on our rib, wake is a bit small though so i spose no good for jumping

As someone who works where they sell sports boats, but own a RIB, I see no reason for the 7.5m Cobra to be any heavier than an equivalant sized sports boat (which would probably have an inboard motor anyway). I have skied behind my old 6.5m Ribtec fine and a few other RIBS, plus behind some sports boats and there is really no difference in pull out. If it is slightly slugish onto the plane you could always just prop it down to allow for better acceleration, but I doubt that would really be neccessary.

RIB BOI · 26 January 2006, 19:55

Wakeboardin behind ares is easy on pull up with about 6 ppl in the boat full tank of fuel and about 5 wakeboards n god know wot ova crap. so i recon your pick up will be much quicker.

Roy Smith · 26 January 2006, 20:23

I had a 7.5 Cobra and can confirm that with a 225 four stroke 6 up and one in the water you can with ease pull a mono skier as for the weight what would the differance be been a hard boat and rib of this size ?

Thanks Jeff

That was with 5 adults on board and a 21" prop too.

If I had more people all I would need to do is drop down to a 19" prop...
