Oh man! I've seen a frontal of that before, not great - but dear God - what a horrible interior!

RIBase
its not pretty but its functional and if it gets a bit more use out of your boat I can't fault that .its better than days getting cancelled due to shit weather I think with some proper sculpting this would be okay

It's been done before. I presume whisper got this mould when he took over from biffer

no secret anymore

Fast Forward refit

Some of the early scorpions cabins rested on tubes and were glasses down over tubes. From memory though the valve holes remained open for access and one was nearly lost at sea cause of it. Think they changed that design

I've done what you're planning and to answer your question about fastening to the boat, I chose a hull where the deck is not flush with the internal tube flange so there is some hull side above the deck. The cabin mounting points are bolted through the hull side so access is available for mounting both inside and outside the hull. Plainly, there's more to it than a few bolts through the hull but that's the method of fastening.

If you're going to embark on this build project, consider, swither and plan and then do it some more until you're very sure of your requirement before you start. Particularly, you must decide whether you will live in it for any length of time because that with dictate much of the build plan and materials. Also, consider where you are likely to do your boating because your cabin may need to withstand a serious beating. Then, model it in cardboard to get a final feel for it from inside and out. The model need only be a couple of hundred millimeters tall but it's an essential exercise when designing in my view.

So, your living requirements, your structural requirements and the aerodynamic and styling requirements....get out the resin and brushes, what are you waiting for!?....

It's a bit bigger than the size you've indicated.

I think to achieve a berth rather than a shelter, 8m is possibly a little short for a cabin rib.

If you are happy to erect a 'tent' at the end of the day, it widens your options considerably but from your questions it sounds like you want a proper cabin.

In terms of attaching a cabin, I'm a fan of Sikaflex. You do need to prep the surfaces properly though.

Is a rib the best type of boat if you are after an 8m cabin 'cruiser'? If you were to compare a rib against a Beneteau Antares 8, for example, you get a lot more bang for you buck out of the Beneteau.

As it's more of an affair of the heart than the head, I'd be looking at the advert at the top in more detail and persuading myself that 2 extra metres wasn't too much!

Good luck with the search.

OR YOU COULD...
Forget the Cardboard and Scissors and Sicoflex and search around for something new OR used (Professionally built) you can ACTULLY look at and get aboard!
A finished article which at your leisure you can appraise...The Size/Room Test drive...Guage the Feel/Performance/Balance/Sea Keeping...economy...inspect the quality of Build and finish....AND give a "serious beating" in the first instance...for real!..
At the very least you'll then have some idea if THAT.... (or ANY) Cabin Rib is going to be right for you
As for Biffers Cabin RIB's...he built quite a few...and did it for a living!
