I'm really pleased with mine...........nice big Rib and as posted previously has just had a thumbs up from the surveyor.
Nasher on this forum has an Ocean too. He was really helpful when looking at mine (see earlier mails etc) and would probably be better placed to answer any specific questions you may have - although I will help if I can.
I have also been in contact with Malcolm Winsor (boat builder) both prior to, and since buying the Rib, and he has been incredibly helpful with tech questions (see www.oceanribs.co.uk
With regards weight, i am due to take mine to the local weighbridge at some point (no immediate plans), as i am hoping to secure a small contract where i would need to tow the boat, and need to see if my combined vehicle and towed weight exceed 3.5T - if so I'm told I may need a tacho!?!
I will let you know outcome when I get weighed - but this may not be for some weeks (probably too late for you) - Nasher may be able to help though?
