Advice For New Rib-er Please

Hi.

I'm just about to buy my first RIB for cruising, skiing and maybe a bit of diving. I live in Plymouth and aim to have the boat on a pontoon mooring. Years ago i owned a Fletcher Bravo but want something more sea worthy and substantial.

I'm looking at a second hand 6.1m boat which was built as a series of 6 by Olmec tubing in 2005. It has a deep V hull and is powered by a 2003 mariner 90 (not sure if two stroke or 4) with 160 engine hours. The boat is in pretty spotless nick and is currently owned by an ex Olmec Engineer. It has lots of accessories and a claimed flat water top speed of "50mph". I'm due to give it a sea trial shortly. Its on for £9500 ono.

Questions are:

1. Does this sound like a good deal?
2. What specific issues should I be looking out for?

Any help appreciated

Jon

Hi Jon,

A 2003 model shouldn't be a concern. 50 mph with a 90HP is a bit generous. I would estimate 40 mph tops, on a FLAT day.

Being from across the pond, I'm not familiar with the boat/ model, but at 9500, it sounds like a good first RIB. If you have any pictures, do post them.

Agreed, You would need a 135 to get 50 without question.

This is probably the boat you are discussing: http://www.boatsandoutboards.co.uk/view/F79336

May be worthing PMing Rich L as he has an Olmec 6.1 and a 100HP Yamaha on it. 50mph sounds high but they are quick boats, not many about so the performce is abit unknown. Interestingly, Solent Ribs claim similar performance from their 5.4/90hp.......

If that is the boat, I'd be careful of an unbraked trailer, as that lot is likely to weigh in above 750kg.

apparently they are quite a narrow boat so they may be quite fast. i would seriously question the trailer as it would be a problem if unbraked


consider the following
engine weigh in at say 150 kg
fuel at 70kg
fuel tank at 20 kg
trailer at say 250 kg

that means you have 260 kg left for the entire boat, tubes, seats, upholstery, console, steering, gauges, controlls, rigging etc etc

i would be very surprised if that boat came in at that weight and if it did i would worry about it being tooo light a build!!

my bare boat with no tubes and other bits is 6.5m and 520kg

I knew someone who owned a ohlmec 6.1 with an unbraked trailer-170kg engine-and he thought it really needed a braked trailer.

Hi Jon

I have this same boat - except this one is better because it has a better console arrangement and under deck tank.

Mine has a Yam 100 4 stoke and the boat tops at about 41mph. A 2 stroke 90 would most likely be quite a bit quicker. Someone I know has a 130 2 stoke and reckons he gets 60mph (or knots I can't remember) but I have no reason not to believe him.

This is a great boat, often compared to a V-Type (no, it's not a V-Type!). It's very light and has a very good balanced feel to it on the water. Deep V is a bit of an exageration IMO but it handles very well in all kinds of conditions. It IS good in a swell (and I've seen some serious swells) and it excels when there isn't. But it's not a 'lifeboat'.

I seriously love this boat and would buy another. I've owned a Humber and a Chinook and this is far better.

AND the hull has been used for racing (successfully) - ask cookie.

The hull IS narrow and it's one of those RIBs where you are feel like your sitting on top of the water rather than 'inside' a boat - more so than your average RIB. But these features combine to give it a very 'nimble', responsive feel. And it's easy to tow.

Weight - well it is seriously light. I've never weighed it but I tow it on an unbraked trailer. I reckon it's bordering on 750kg. I certainly never had a problem and drive hundreds of miles with it (sometimes loaded with holiday gear I must admit).

Remember that the boat is one of very few. (I love that). But you may have a problem selling. That's unfortunate bacause people are seriously missing out!

Take it out fro a trial and test (measure) the speed and handling for yourself.

I'll have mine at the RIB raid in Wales & anyone is welcome to have a go.

ps I have no connection with Olmec whatsoever and bought mine on the strength of a test drive.
