Eco friendly Ribs

limeydal · 02 July 2005, 03:03

Putting together a project to try and get the Port district interested in a RIB tour operation here in San Diego.
They are very "environmentaly motivated"; as regulations concerning pollution and emissions are the most stringent in the country here.
I have heard of RIBs being used on the barrier reef and other sensative areas and looking for any examples I can use to promote them.
Is anyone aware of any online articles/documentation/websites or other relavent material that might help?

Would have thought it would mainly come down to engine choice etc. Also waterjet propulsion to avoid chopping up the wildlife.

These people make a big thing of being kind too the environment etc.

Remember greenpeace etc use ribs a lot!!! As to most environment protection agencies so if it is ok for them to use one.........

Thanks,useful stuff.
I had heard of several agencies using RIB's so just needed some actual examples.Will have to check out Greenpeace next.
We have a very landlocked bay here and they are even complaining that the cruise ships are running their diesel generators while in port and adding to the pollution. So really getting strict.
Seems a RIB with low emision engines would suit the job here.

Read a bit on LPG conversions also,but seem mixed results

I will check on some of the environmental agencies and see if they have any info;

Just a thought but what is the local situation regarding BBQs??? In the UK the government have issued a warning over air pollution in the summer - they say about not lighting bonfires and even suggest not using your car for short journeys etc - no mention of BBQs - they put our FAR more pollution than ANY car!!!

What about using bio diesel? Modern versions can be put straight into a normal diesel engine. You could also be a carbon nuetral company which is what we aim to be at www.marinediscovery.co.uk.

Was also researching LPG but read some very negative things about the life expectancy of converted engines.
Anyone using it?

Don't know anyone using it on a boat but loads of people use it on V8 landrovers - saves quite a bit on running costs in the UK. As long as it is a good conversion then people don't have any problems - forklift trucks run perfectly well on the stuff as do many generators.

Yes, you would think it would work well.
Found a link to LPGTech in australia who claimed a 40% in cost running converted Yamaha outboards.
Seems that site no longer available!!!
Wonder what happened to them?
Also saw some mercruiser conversions but still nothing on outboards.Will keep looking

This Dutch company are one of the biggest makers - they SAY they are also suitable for outboards but everything seems to be geared towards big petrol inboards.

Outboards are more complex as the fuel also carries the lube unless it is of the oil injection type. also the engines tilt and swivel which adds to the probs.

I think Barrus have done some work on this?

Dal,

These guys have an environmental statement on their website which goes into some of the stuff that they have done for their RIB business.

Hope it helps!!

You might find a waterjet can disturb the seabed a considerable distance below the jet.

Yes but I think they would rather be disturbed than dismembered!!!

For disturb, read, sooked up.

JW; What you mean sent to market!!....rock the Khazbar!

I would have thought any US engine designed to run on unleaded would cope with LPG. You could also blow a diesel with it, this allows better combustion and produces very clean exhaust gases. A waterjet though unkind to shallow seabeds will do less damage to surface floating mamals or divers.
