When Monsters Ruled the Beach


Recommended Posts

I was looking at the revived Worrell 1000 site and I see that the race is being held using Formula 18 boats.   That's a great choice, and those are some seriously advanced machines.   

It reminded me though of the excitement of the beach cat scene in the late 1980s and early 1990s when the Worrell was in full swing and the beach cat market was still much bigger in the USA, with several companies battling for the King of the Beach, and in typical American style - yes, size was a factor!    Without further ado: When Monsters Ruled the Beach:  the over 18' beach cats of the 1980s and 1990s.

NACRA 5.8 - 1982 - Stepping beyond the bounds
The first NACRA, the 5.2 was 17" long, still a foot shorter than the Hobie 18, but none the less a faster boat, albeit a lot more complicated and somewhat less beachable with the long  daggerboards (ask me how I know!).   By 1982 it was time for the category killer, and NACRA came out with this 19' weapon.   They got something right.  The boat is still in production in Australia (albeit with modernized sails), and is one of the largest one-designs down under. 
LOA: 19'  Beam: 8' (not 8'6")  Weight: 390 lbs  Sail Area: 241 sq. ft.

Prindle 19 - 1985  - A big fast boat for traditionalists
Looking a bit like a scaled up Hobie 18, and using the same retracting centerboard, the Prindle was their salvo in the battle of the over 18" beach cats.  It enjoyed a strong following and success in racing, where it's rival was always the NACRA 5.8   It was Prindle's swan song as a manufacturer.  After their acquisition/merger with NACRA, the new company did not continue with the Prindle brand name.   The boat had a reputation as quite robust and fast.
(19'2" X 8'6"   390 lbs.  Sail Area: 247 sq. ft.

NACRA 6.0 -1988 - First of the modern giants  
Not to be outdone by Prindle (who they shortly thereafter merged with to form Performance Catamarans) NACRA answered the Prindle 19 with the NACRA 6.0 - a full 20' x 8.6" platform    NACRA had already experimented with beyond 8' beam with the 18 squared , so they had some background with big boats.  The 6.0 was designed to meet the revived (1985) Worrell 1000 20' rule. 

20' X 8.5"  420 lbs.   Sail Area:  264 sq. feet   (Originally no spinnaker, I believe the "NA" was the spinnaker upgrade, with the distinctive forward spreader)

Tom Roland designed the original NACRA, the 5.2 in 1975.    By 1988 Roy Seaman had taken over the pen for the NACRA 6.0.

The Hobie  Cat 21 - 1987 Too much of a good thing 
While the developing idea of "Formula 20" (along with the Worrell rules) kept the performance beach cats caged in at 20 feet LOA,  Hobie, who had always been big into recreational sailing saw an opportunity to go hog wild and built a giant beach cat for pure fun.    The Hobie Cat 21 came in several editions SE and SC (Sport Cruiser), with various goodies. including a front trampoline.   The "wings" were a big Hobie thing at the time, the Hobie 17 single-hander came standard with them.   At 10 feet across it needed a tilting trailer to transport, which along with the girth didn't help popularity.  It lasted only 3 years in the market. But one might say some of it's DNA lives on in Hobie's rotomolded Getaway, albeit in a diminished format.  
LOA: 21' 4"  Beam: 10'  Weight 639 lbs.  Sail Area:  Main: 229 sq.ft.  Jib: 88 sq.ft.  Asym Spin: 312 sq,ft,

Hobie Miracle 20 - 1991.The Empire Strikes Back
Hobie seemed to have finally taken up the challenge of Nacra, Prindle and Supercat and left behind their 60s design vocabulary with the 20.   It was 19' 7" long, with a 195 sq. ft main, 55 sq.ft. jib, and huge 226 ft. asymmetrical spinniker.  This stuff is common now, but not then. At 420lb it wasn't *that* much heavier than a Hobie 18.

Supercat 221992 -  The Beast from the East 
Off on the East Coast designer Bill Roberts had developed the Supercat as an early alternative to the Hobie.   A 15' and 17' were both popular.   By 1992 Roberts seemingly decided to enter the giant beachcat war with his own statement, the Supercat 22'.   Living and sailing in California I never saw one of these, although there were a couple of the older, smaller Supercat's around.  Robert's went on to build even larger beach cats: the RC-30.    Roberts restarted as Aquarius Sails and still sells a lightly updated version of the beast, and other Supercat designs, under slightly modded names.

G-Force 21- 1989 The sound of a different drummer
G-Cat had made their mark building fun off the beach cats in the popular 16 and 18 foot lengths.  Their original hull design was boardless, like the Hobie 16, but in place of the Hobie's asymetrical hulls the G-Cats employed symetric hulls.  The G-Force 21 kept this unusual design as it super-sized it.  At some point in the1990s the rules for at least one running of the Worrell 1000 were changed  to allow production boats up to 21" - and the G-Cat got in on the fun, and finished second (against Randy Smyth, who then as now was pretty hard to beat). 
LOA: 21'  Beam: 12'   Mast height: 31'

The front tramp made it an interesting mix of simple, comfortable and fast.  
Not many were made, and like the SC-22 I've never seen one in real life. 


CODA:  After the age of giants
Most of the giants are gone, indeed most of the companies that built them are gone!  Today we have the F-18, a very successful class that is perhaps near the ideal for a towable, beach cat with a maximum beam of 8'6"  (towing limit in the USA).    

NACRA alone has continued to evolve their NACRA 6,0, into todays Nacra 20 Carbon FCS.  It's a beautiful boat and frequently wins line honors in European point-to-point races like the Round Texel (and a very expensive one at a cool $50,000).   But it's rarity, focus, expense and exotic construction somehow separate it from the vintage boats of the Age of Giant Beach Cats.

NOTES: 
1. Sailboat Data .com
has specs on a lot of these boats.  (I don't know how accurate they are) https://sailboatdata.com/

2.  There were a variety of rating schemes at use at the time.   Today the SCHRS  (Small Catamaran Handicap Rating System) seems to have won out as the most up-to-date and universal data set.   Many of the boats discussed are rated there.  (Site seems to be down at the moment). 

3. It's interesting. Formula 18 seems very healhty, judged by their web site and many events.  Formula 16, perhaps less heathy, and active in fewer places. The main Federation web site seems to be gone, which can't be a good thing.  Formula 20, meanwhile, never really took off - and the B Class didn't thrive either. 

4. Of course, the original oversized beach cat is the Tornado - originally designed to meet the IYRU "B Class" rules of 20 ft. LOA,  10 ft. beam and 235 sq. feet of sail, it won the test the IYRU held.  It was then selected as the Olympic multihull, and from 1976 for 9 successive Olympics, ending it's run in 2008, was the only multihull in the Olympics.  The first (and only) time I saw one was around 1985, on a trip to Bermuda.  It was inspirational!  The first - and some would argue - still the greatest of the 20 footers.  It got a new sail plan in 2001, inspired by the antics and innovations of it's cousins, I am sure.

Left out the Mystere 6.0 :-)  I had the privilege of racing in the Catamaran Racing Association of the Chesapeake (CRAC) when open races still attracted sizable fleets.  Nacra 5.8s and 6.0s, Mysteres, Hobie 20s, Prindle 19s, and the old single-trap Tornados mixing it up with the occasional Nacra 18 Square.  A good sailor on any one of these might beat any of the other brands.  Fun times; pretty much went away along with the 100-boat plus Hobie events :-(  

ps:  I'll take the A Cat over any one of these for ease of setup and moving on the beach :-)

I'm still enjoying my Nacra 5.5 (ex 18 sq) with a bunch of local og's.  Our group has owned and sailed most all of the above and now sails P19s, 18.2s, Tornado, Acats, Darts and even a Weta.  I've sailed on plenty of boats but in the right conditions there really isn't anything more fun than a good beachcat.

Yup. There are dryer experiences, you could foil for more speed, and some folks want the thrill of matching shirts with fellow rail-meat... but for broadest grins at 10-20 knots, for my paltry dollars, beachcats are the best!

The A-cat truly wins in terms of ease of use. It's crazy to see how much design has changed since the 80s. I guess we have to thank the America's cup for that... 

For beach cats, aside from foiling, which is obviously a breakthrough, has the beach cat really changed that much?   I can see it both ways.  Lots of small changes add up, but also it's not that different? 

I'd argue that there was more change between the Hobie 16 and the NACRA 5.2 than between the NACRA 5.2 and the NACRA Infusion. 
And how much difference is there really between the Infusion and the Evolution?  

The reverse wave piercing bows have made the boats look different, finally.

The NACRA Evolution: 

Nacra F18 Evolution | East Coast Sailboats

Maybe Tom Roland doesn't get enough credit for how good his design of the NACRA 5.2 was.  The "Evolution" is well named. 
The much loved Hobie 16 was an evolutionary dead end.  Hobie kept trying to borrow design notes from it for 20 years, but finally gave up with the Miracle 20,  which, let's be honest, looked a lot like a NACRA.    With the Tiger I believe they licensed an existing boat from the French designer.  


Getting back to the Worrell 1000 -- here's the breakdown of the boats by brand/model: 

  • 4  --  NACRA Evolution
  • 3 --   NACRA F-18 / Infusion 
  • 2 --  Goodall C2
  • 1 --  C3 
  • 1 --  Edge
  • 3 --  unspecified F-18

It's interesting to me how confident so many people are in the Evolution.  I guess some people are getting experienced with them, but  I've wondered if it's really a better design for the open ocean than the older Infusion.  I notice no one (as far as we can tell) is entering on a Hobie Wild Cat.     Maybe I'm just still looking at the reverse angle wave-piercing hulls with a too much skepticism still.   But the Wild Cat did get a reputation for preferring smoother water as I recall.

Stars and Stripes 1988.    I think the C-class really developed the wing-sail up to the point that it could be used on Stars and Stripes.

That is cool!  Which one is your boat?   
I just grabbed all these off the net, because Sailing Anarchy does a lot better with URL's than uploads! 

*A belated thank-you to all the people providing images to this thread* 

And, here's a couple pictures of the missing Mystere 6.0

Aa for specs or history - it's a bit of a mystere ! 
I think my location in Santa Cruz during the Age of Giants meant that I 
saw a lot of West Coast manufactured cats:   Hobies, NACRAs and Prindles, 
and not very much of anything else (except I do remember the Supercat 17, but they Supercat was owned by Boston Whaler at one point, so they had serious distribution.

thanks for the great writeup, the Nacra 5.8 is indeed going well in Aus, we had 21 on the start line for the National titles last January and were expecting a lot more this year at Hervey Bay for the Nationals but due to Covid that has been put off for a year.IMG_4059.thumb.JPG.f7d69914d408539214758551f6c3d5fa.JPGIMG_4153.thumb.JPG.5fcada33fdee74dbdff9d73739ed4ac4.JPG

The way i remember the past is that the Tornado came out first in the late 60's, taking the fastest production sailboat honor from the Shark (also 20x10).  My first crewing gig was on a Tornado 1968. The hobie 14 came out also late 60s.  Tornado wasn't used much in the Worrell since it isn't good to run up on the beach at full speed because of the centerboard gaskets for one thing.

There was a 10m foot wide alfa cat from the guys that made nacras before the 5.2 came out.  The 5.2 being more like a tornado as an answer to the popular hobie 16.  we destroyed the naca 5.2 fleet in sfo multihull championships with a hobie 18 in the late 70s.  Also beat a bunch of 5.2s with an gcat 5.0 in hurricane gulch earlyn 80s.

Prindle with Richard Loufec made the 19 as a tornado training boat- very similar hulls, crappy centerboards, but a bigger rig.  Smyth and others put a asy on the 19 and won the Worrell.  There were 2 -19s and some nacra 5.8s all with asy rigs that year.  The asy was rigged off the leeward bow in the beginning.  I raced 1 of of the 2 boats in the fleet w/o a spi. and got crushed.  I later realized that if we had tipped over with that front tramp on, we would not have been able to get back on the boat very easily after re-righting.  A very dangerous situ.

The worrell was started on H16s by Mike Worrell, and was non stop in the beginning.  The race lasted for nearly a decade on regular hobie 16s, IRRC.

From the side, my current trimaran looks a lot like these 19 footers.  But it weighs double or more.  Little doubt which is the more exciting ride.  image.thumb.png.075a303405af0ada88b1b78f87d35bd0.png

Miami to Key Largo was always fun too......huge number of boats at the start. Bill Roberts in the RC33 used to cream everyone.

Worrell was the stuff of legends. My 6.0 was still my favorite cats (just behind the Prindle 18.2)...........really was a great boat in the in the ocean.....

We all kept our boats on the beach anchored with a 5 gallon bucket of concrete buried in the sand, ahhh, the good 'ol days!!!!

Great read!  A few things, some of which fit with the Worrell and some not, and likely a few goofs...

The Nacra 6.0 didn't come factory with a spin.  Spins were definitely added for distance racing. There was the 6.0, the 6.0 Express (A Randy Smyth creation) and the NA.  The NA for both the 5.8 and 6.0 brought the bow foil with a bigger jib.  On the 6.0 the NA also got a taller rig with double diamond wires.  The Express had a taller rig and perhaps a spin, but not sure if it was an official Nacra model.  Most 6.0NAs have had spins added (they certainly did for the Worrell).  I loved my 6.0NA probably the most out of the cats I've had, even without a spin.  One nice thing about the 5.8, 6.0, and the I/N 20 is that they tolerated heavier crew weights. 

The Prindle 19 was more akin to a scaled down Tornado.

The Hobie 20 class didn't have a spinnaker, although you could add a kit from Hobie I believe.  The 20 is also a sweet sailing boat, in a different way than the 6.0, and not as tough (at least mine wasn't).

The Hobie 21 in it's two versions - the SE and SC.  The SE is the one with the 10 foot beam (not counting the wings).  You didn't use a tilt trailer - it had curved beams that telescoped down to a trailerable width.  The trailers usually had sliding supports to help manage the process.  The SCs (Sport Cruiser) went to a straight beam at a trailerable width (with the wings removed).  The 21 SC was featured in a supporting role in the ProSail Formula 40 series (find those and watch if you haven't).

Non-Worrell - In the time of wings at Hobie you also had the 18 Magnum and the 18 SX.  The Magnum was simply an 18 with wings added (two different versions).  The SX fitted longer wings, a taller rig with mylar main, and a spinnaker.  Still a great knock about beach boat.

IMO I'd say that Nacra didn't really evolve the 6.0 into the current 20, except to say that the boats are similar in length.  The one really deserving boat not featured above is the Inter-20 (or Nacra 20 as it was renamed).  This boat was so different from the N6.0NA that I don't think you could call it an evolution.  The same, by the way for the transition from the Nacra 20 to the current Nacra 20 CF/FCS, so different I wouldn't say evolve IMO.

The Inter/Nacra 20 became the boat for distance racing in the US for years.  Worrell 1000, Tybee 500, Atlantic 500, etc.  Insanely buoyant bows, a tall carbon fiber mast, spinnaker, and typical Nacra toughness.  Probably one of the best bang for the buck boats on the used market for a used performance sail boat, again IMO. A lot of these boats have done duty in the big races and still provide a solid platform for good sailing (mine is one of these).  The F-18s have now edged these out as the distance racing class, which in some ways feels a little sad, but that's where the action is these days.

I would say that the Inter20 was the first boat to be designed with a spinnaker in mind [Rather than retro fit]? or was it the very early F18s? The inter20 predated the inter 18 but maybe the dart Hawk was before the i20?

And of course, it's hard to keep SE and SC straight - it is the SE that had the role in the ProSail series, not the SC.  The SC came with a smaller rig and a cubby for camping gear and cooler, not a good config for a series like the ProSail...

Certainly one of the first in that new breed, if not the first.  Around that time the Tornados were transitioning to the updated rig, The Hobie 21 SE and Hobie 18 SX were there.  But those might be considered add-on updates versus a boat designed from scratch with a spin as part of the package.  Not sure of the timing relative to the F-18 development and boats like the Hobie Tiger.  Certainly one of the things that made the I-20 package more appealing to some was the end pole snuffer, which certainly simplified spin handling from the bag launch days but does add windage, with a mid-pole design coming later.

I got my Bim F 20 cat boat (10.50 m mast), designed with a spinaker, in 1989, the Ventilo F20 cat boat (11 m mast) appeared a little after. They were much faster than original Olympic Tornado and soon, Sailing authorities knocked them with unfair rating !
