Arctic, Atlantic, Pacific.

The current thread about "RIB in boatyard" has various references to Atlantics, Pacifics & Artics & it occurred to me that I don't actually know what the difference is between 'em. Anyone care to enlighten me I'm assuming that they are all made by Halmatic, or is that incorrect?

The Atlantic 21 was developed at Atlantic college in Wales, I think in the late 1960s and looked slightly different to the more modern version with a shallower deadrise. The craft was adopted by the RNLI and many were made out if timber at William Osborne's at Littlehampton. This is also where the Medina was made. The RNLI, dropped its interest in the larger RIbs while the Dutch expanded on the designs.

I think the Pacific's were next, there was a very early P24 at Stonehaven in the late 1970s. The Pacific's were a longer version of the A21 but were Diesel powered, usually with an outdrive.

The Hulls were then slightly modified. The Atlantic 21s kept the flat section running from the centre to aft for beaching purposes. The Pacific's had a more rounded hull. Then the smaller Pacific's were fitted with Outboards for the offshore standby industry and were named Atlantic's once more, usually the A22. The larger A24 was utilised for Airport Rescue.

The Pacific's remained as Diesel Powered craft.

Halmatic bought the plugs and the rights from Wm Osborne's in the early 1980's and made the moulds to produce them in GRP, I assume it was Halmatic that modified the base.

One unusual craft was the A25 at Stonehaven, it was made out of Aluminium in about 1983 and was outboard powered with a small wheelhouse, this was the first small cabin Rib. The Cabin was very cramped and deemed to be a death trap in a capsize situation being open. The craft was returned to Osborne's in late 1984 and converted to Diesel with PP water jet propulsion and renamed as a Pacific.

The largest Pacific at the time was the P36, wth twin 212 Ford Sabre Diesels and outdrive, later modified to V - Drive and a keel added for greater Seakeeping effectiveness. These entered service as Offshore Daughter Craft in 1985 for Seaboard Offshore in the Brent Oilfield. I will post some photos if I can find them. I have a picture of 2 A22s and 2 P36s on the same ship.

I hadn't a clue either, but I've done a LOT of research on the subject on RIBnet. My findings:

Atlantics, Artics and Pacifics (AAPs) were RIBs purchased by organisations that were wealthy enough to be able to avoid Seariders. They were produced in Orange and/or Grey. Some were Black but if I were to tell you about those, I'd have to kill you. AFAIK, they were all built with red brick and corrugated steel (or whatever you build brick sh1thouses from in the UK). AAPs are highly sought after but mere mortals cannot buy a working example. Instead they must buy a "project" grade bargain. These are generally kept in sheds, often for years, as the new owner seeks parts and funding. A "shed class" AAP can cause quite a lot of confusion, as they can be difficult to tell apart. A giveaway is evidence of inboard engine mounts, confirming that it was once a Pac. Tubes too are often a source of grief, as they are scarce and pricey. CITEs raids have accounted for a lot of the scarcity, when used AAP sponsons have been mistaken (by appearance and smell) for elephant body parts and destroyed. Attempts to "home grow" AAPs by feeding steroids to SR5.4s have so far failed to bear fruit as instead of butching up, the Seariders merely grew additional antenna and safety equipment.

Spotter Guide:

Orange with missing outboards - Atlantic
Grey with missing outboards - Arctic
Grey with missing inboard - Pacific
Grey/Black with missing inboardS - very large Pacific

There is also an Arctic 20, we did about 4 of them for the Greek Navy, all had twin Mercury 90 2 strokes. They were crazy fast and we had to turn them all down to 75hp!.
