Oshum Dynamix Advise

Does anybody on this site drive an Oshun dynamix Ribworker. If so can you tell me what they handle like in a roughish sea (2 m swell, 30 plus winds). O am finfing this one very bouncy when I am coming alonside the stationaru vessell. Any hints or tips particularlu re revs kigh or low when coming alonside.

I have boy hit the hip yet but It is looking more and more likely

cheers

Forget revs.

Loads of Velcro on the toobs and vessel will work.

If the boat your coming alongside is very large, which I'd assume it is, get a good length stern rope onto her and keep some power on. This will slow down the movement, and I'd assume that the "mother ship" is fitted with DP so she wont move off station whilst you do this.
I've been out on some crew transfers to warships carrying out sea trials and it is much easier going alongside when both boats are moving, however when they are at anchor we put up 2 stern lines, in case one breaks mid transfer, and keep the outside engine ahead, this slows down the pitching and we have carried out transfers in a F8, the boys like to come ashore The boat does tend to swing at her mooring ever so slightly, but by the time it becomes a prob we have left.

Thanks Mark I guess it would have to be industrial strength!


Andy, The problems are occuring picking up the ropes, the boat does have DP and yep I sure do wish it was moving. The rib pitches about a quater of a metre with the waves. We use an FRC for transfering people this problem is when we are recovering the 12 metre to deck!

I have been picking up the bow rope and pinning on using reverse thrust I will try using the stern ropes instead! The Rib considering it weighs seven tons is very sensitive to a wave!

I told em we should be using Phantom 28 s but they would just not listen. ( private joke)

cheers

Would have been cheaper though sitting on a trailer 11 months of the year.

The Rib which is suberply equipped actually goes out for 7 grand a day It only works three months a year and it has paid for itself in three years.

There is something SO right about those Ocean Dynamics boats - serious tough an built for the job - I would have thopught there is NO better boat for operating in shallow rough water or for surf rescue work etc. Maybe in deeper water though the water jet isn't as good as a conventional prop???

It is OK now I bit the bullet and am using bigger revs and a bit less air in the ruubs! it gives me better contol!

I think the Jet is OK for deep sea use and I think that props are'not welcome in the north sea diving arena. I mat be wrong on this but I see em as being a lot safer
