Redbay 9.1 or Ribcraft 9.0?

Just wondering if anyone has experience of BOTH of these boats and is able to give an objective opinion as to which is the best seaboat/gives the softest ride head to sea?

Thanks

I think youíll struggle to find many people 9.1ís are not very common. Are you comparing a heavy, twin engined cabin diesel with an O/b driven boat? Not quite apples and oranges, but maybe apples and pears!

Some Redbay 9.1ís were fitted with a single Yamaha diesel and plenty of Ribcraft 9mís are single diesel so a good like for like comparison there.

But to find someone who has experience of both could be a challenge

From the off I'll say I haven't driven either, but I may have some useful info anyway regarding the Redbay 9.1m

First, we don't know which layouts you're contemplating - I'm guessing possibly almost fully open or Big Console styles? It's going to make a difference, because the final iteration of Stormforce 9.1s were fully decked with hard cabins and twin diesels - a long way from the very early almost open boats with singles and well decks.

It's worth considering the evolution of the hull - Redbay were working their way up successive hull sizes in the run up to the development of the 9.1m. The family owned multiple copies of each size and ran them throughout the islands of Scotland, returning to the drawing board every couple of seasons to refine their designs. Years of experimentation gave rise to the 9.1m hullform. Extremely beamy and well planted, it incorporated the hard nose to reduce the risks associated with stuffing in big seas. I had a conversation with a professional skipper when researching my own hull (not the 9.1m mould). He had owned at least two 9.1m and also the 11m which is an extension of the 9.1m mould. He said that this hull was absolutely unparalleled in a following sea - his words being that the 9.1/11m was special and the rest were "just RIBs".
My own feeling is that they need a lot of power to do them justice - the tubes stay firmly in the water under way. I also know that they are a "wide load" on the road - too big and heavy to travel on a boat trailer.

Hi Wilk,

Many thanks for your informed response.

You are quite right assuming I am considering a fairly basic setup by Redbayís standards i.e. open RIB with large console etc.

Iíve had some experience with the Ribcraft in varying conditions and do like the way it performs. Iíve also had a quick blast in a Redbay 11m with full wheelhouse but as you rightly say, that is very different boat and by no means a direct comparison, hence my initial (maybe optimistic) question.

Outright speed isnít a real priority nor is trailering her, so the priority for me really lies with comfort and ride quality at sea (build quality etc appears fairly equal).

I can see your point regarding the benefits of the hard nose in a following sea but wonder how she performs head to sea?

Just to confuse things, the skipper of the 11m that I had a trip in thought she gave a very hard and uncomfortable ride head to sea. I canít comment as it was flat calm that particular day but his opinions seemed to be the opposite of the general consensus although he was quite experienced.

In the case of the 9.1, I wonder whether she performs best with or without the extra weight of the flush deck and wheelhouse? Quite often the original, more basic variants are better. I should also add that I very much like the design of the Redbay, hence my enquiry! Thanks

I really can't clarify that skipper's comments! I've run alongside 9.1s and 11s in 3m seas (both directions) and my impression was that they were doing just fine! Head seas can be uncomfortable, but it's a following sea that will kill your boat.

You're right about extra weight - it increases the forces experienced when hitting waves. I'd take a 9.1m to sea before my own 10m hull - the legend is THAT powerful!

SF RD 9.1 Hull

NJ64,

RB 9.1 SF rib is one of the best all time RIBs made by the team at Redbay Boats Tom Paddy & Joe !!!

I have done a lot of cruising on 9.1 & owned a 11mtr RB C/W twin 315hp Yam IBD.

RB 9.1 SF was designed by Joe McCollam a naval architect. The brief on the design for the 9.1 was twin diesel & when running at 25/30kn for the tubes just to be above the water line. First rib out the mould was Castor & was fitted out with twin 180hp merc diesel on B3 drives. Second rib out the mould was Gulfstream fitted with twin Yam 165hp IBD. This turned out to be a fantastic combination so much so that Castor was refitted to have twin Yam 165hp. Then a 9.1 was built for the Gibraltar Police & was fitted with twin 240hp IBD Yams with a top speed of over 40kn. A fantastic RIB that I had a run out on C/W blues & twos.

I can highly recommend the 9.1 hull as one of the best hulls on the market place & hard nose is a fantastic design by J McC.

I have been out in very big seas of all types in our 11 RB & one trip back from the North West 200 Portrush to Campbelltown in a force 8 & it was like Hawaii five 0. We were 30kn coming down waves with no power then 600 horses full on going back up.

There should be a very good RIB international write up on the 9.1 & there is a bit about our 6.1 C/W 150GT Johnson outboard:

Joe McCollam on our 6.1 had HMS from RIB magazine on our boat from Rathlin to Redbay & they played in the waves. He said "one of the most sure-footed craft of itís size I can remembering handling" (Hugo Montgomery Swan from RIB International).

Give Joe a call he is a top man ( 07557 912520 )

All the best Callum.

I keep bumping into Gulfstream - still looking a million dollars and a stunning craft. She buzzed me mid-Irish Sea with the floating Land Rover thingy and we were alongside each other at Ardbeg last year - we're the classy looking boats on the raft off Lagavulin running west to east...

Hi Callum and Willk,

Thanks both for taking the time to respond, the information that youíve passed on has been really helpful.

I saw a photo of Gulf Stream recently complete with gleaming teak decks and she really did look the part. Do you happen to know how many 9.1ís were built to this design?

I will definitely give Joe a call as suggested and see what transpires... Hopefully see you on the water sometime.

Thanks again.
