Four Stroke and Water Skiing

[ncp]

Those would be great prices. Last I've heard (and only example I've heard): Oahu, Hawaii, USA To Los Angeles, California, USA for a 7.3m on a trailer (no arch, no t-top, etc. because they do factor volume) was ~$4000US.

Hi, I m new to the forum. I have a zodiac pro open 550 with a yam F100 4 stoke. The boat weighs 450kg plus 200 for the engine. It easily pulls a skier with up to 8 people on board. 150 hp should be efficient on your.

Thanks everyone for your awesome information, opinions and advice.

I am going to go ahead with the Chinese supplied 6m RIB. I understand there is a risky element to it but the savings are just too great to not give it a go. The fibreglassing hopefully won't be an issue as the boat weight seems good. I was concerned with the expansion / contraction issue of the tubes causing an eventual glue failure issue (so a dealer told me) but the Chinese company use a lot of safety/pressure release values which are supposed to prevent this problem.

I will keep everyone up to date with the quality and some pictures of the new rig when it arrives early August.

I am on the hunt for a Mercury Optimax at the moment - but if a decent HP four stoke comes for sale I will be considering this also as it seems 115HP and over will be okay for waterskiing (will aim for a 130HP though I think).

Any more opinions and advice would still be great as I am checking the thread regularly.

Cheers!

Thats what you get for having a "cabotage act" basically it means you can only transport goods from one US port to another US port on a US built, manned, registered, maintained, and operated vessel. This is hellishly expensive, which is why US flagged "jones act" vessels never trade outside of the US, as they loose shedloads of money!

The World price for Twenty foot, and Forty foot containers is at a very low rate presently as there are many more ships than cargo to fill them. Also bear in mind that a shipping container is only 8 feet wide, to the outside, so probably 7 foot 6 max internal dimensions.

And there's a lot of copied shite.

There's a world of difference between the factories producing Apple products under strict control and the 'UV Dissolver' produced by the Wung Tung Foo Rubber Boat Co.

We have people come into work to have Chinese copy Gennies repaired, without exception, they a utter rubbish.

well we have not used your model so can not comment on how good or bad it is so please email us a review when you have tried it.

re engine. we are big 4 stroke fans i.e. the same as cars for all the obvious reasons and many that are the same as the car manufactures but...... 2 stroke do accelerate quicker so getting the person out of the water is far much easier. yes they are trying to sort this on 4 strokes and some have been come out with some great marketing lines like power thrust model etc. but sorry, they simply are not as good.

so suck up the fuel & oil bill and buy a 2 stroke ( some people on here will claim there is not a lot of difference so you need to work out for yourself who is right on this point) and have fun and be safe.

Also are the four strokes too heavy also?

The reason I ask is a relative suggested if we are wanting to ski, you shouldn't get anything other than a 2 stroke as the low down torque isn't sufficient in a 4 stroke.

I would love anyone's opinions on this.

Thanks everyone.

Dood, seriously, a great new boat that you have to cut the floor out of?

Welcome to RIBnet, btw!

[Samuel_McDonnell]

I purchased a cheap quad bike from China once. The story didn't end well.
