Thanks for the reply Stuey. You've given me a bit to think about. I follow Bills blog at Ke Nalu a bit but he hasnt updated much lately. I'be interested in the conditions they were paddling in and how the board goes head to head with other designs. Isnt there supposed to be some big test for the board showcase sometime? Maybe in March?

" the bulk of the volume in the top of the rails as opposed to the bottom the boards stability actually increases the further you tip it up (quite handy if you're on your way over)!!!!"

I guess this is what I have the most trouble getting my head around. I just cant seem to visualise the different motor skills required. Do you have to stand a different way or use a different method of balancing? I had a few disastrous attempts trying to learn how to paddle a racing surf ski in choppy weather once. The Pene looks to have a similar hull which is why I ask.

" Lobes question 2, are there any conditions where a regular flat bottom 14' Sup will outperform a 14' Penetrator? That's a big "negatory" unless of course you're looking for somewhere to do the ironing!!! Straight paddling speed, the easily driven displacement hull will come out on top every time, into the wind or side chop, same deal with the hull slicing as opposed to slapping. Downwind is where it really comes alive as the quicker speed converts to runners being caught that the slower paddling planning hull may have missed and the additional glide allows the displacement board to continue running long after it's high maintenance planning cousin has dropped off."

What about in breaking surf? I know these are not intended as wave boards but what if you have to get through a break to shore? Are they gonna make it? Does one design have a performance advantage in this (admittedly infrequent) situation?

In answer to your questions Lobes as I said at the end of my last post, the board that's on Maui will be a part of Bills Distance Board Showcase at the end of this month or early next where a bunch of different riders will put a dozen or so of these types of boards through their paces in a variety of conditions, GPS tests etc. and record their findings on the KeNalu website.
Alright, the stability issue again. I used a couple of examples before figuring people would understand that if Bill, (a self confessed, cigar chomping, red wine loving, 62 yr old) who weighs in at 110 kgs can get the Penetrator pretty much wired after 3 weeks of sporadic use, than it shouldn't present too much of a problem for most. Imagine a traditional surfboard type rail and flat bottom, it's at it's most stable when in the bolt upright position, as it tips over further and the rail begins to go under it's righting moment decreases. With the Penetrators undercut rail the reverse occurs, the further over it goes the harder the rail is to submerge and the more it resists, when you think about it this is right when maximum stability is required. It's a slightly different feeling to a more "traditional" board but after just a few goes it becomes second nature.
As for surfing breaking waves on it, much as I discourage it everyone still seems to do this at some stage. Over on Maui, Bill has been surfing it regularly in small waves and having a ball, theres also some pics of Chris De Aboitiz surfing his with his dog on the front on his standuppaddlesurf Australia site.
Cheers,
Stuey

Hey Lobes... Will you be here for the SHQ race in a couple of weeks because there will be a 16' Pene there and you might get to have a go on it if you're lucky..

I'm so stoked to get on the Penetrator that I'm having dreams of it. I'll be the 'canary in the coal mine" as far as stability goes. If I can balance on her and make it work anyone with normal balance will be able to as well. I'll be visiting Bill for 10 days starting Feb 27th and will be paddling all of the distance boards he'll have around....going to be a blast.

Stuey...your explanation of the stability of the 572 is what excites me the most..well the speed too...but one of the problems I have with balance is just that...once I get the rail starting to go in I have a hard time getting it to stop. Really looking forward to testing her out.

Is that a Vortice next to it in the first photo? Theres quite a massive difference in the rocker isnt there.

In the whole design i suppose...

I can testify to Stuey's statement about catching swells that other boards can't, in fact sometimes it's a problem is getting back out of them. If you catch anything going towards the beach you have to jump off to stop it.

I had a great paddle yesterday. I did part of the course that I raced on last weekend. since i raced a 12'2" starboard and let Jeremy Riggs use the Penetrator I had a benchmark to go against. My average speed on the 12'2" was 3.7 MPH. On the Penetrator it was 5.3 MPH. Hmmm.

Sorry I've been neglecting Ke Nalu lately, I promised to help organize part of a race back on the mainland so I had to take a few days to fulfill that obligation. In my other life I race vintage cars, and I whipped up this site to support the race: http://www.crclassic.com . My race car (Peyote) turns 50 this year.

I've got a nice story about Stuey that I'm working on, a whole bunch of great helicopter shots of Mark Raaphorst's boards, and the race board showcase to get organized. I'm also working on the outline and shot list for a e-book on distance SUP: Racing, downwinders, cruising, and fishing. It will be done the same way I'm doing the SUP surfing e-book, as installments on Ke Nalu with the supporting photos, illustrations and video to come later and then wrap the whole thing up into a coherent e-book.

Any help on chapters and pics would be greatly appreciated. Right now Noa Markou is going to do the conditioning chapters.

for that matter the SUP surfing book is only about half done. Anyone that cares to write a contributiion would be most welcome.

finally got the story about Stuey and the Penetrator posted. Came out pretty nice, and I didn't have to do any writing.

Incidentally, I can offer my version of answers to few of the questions that might still remain foggy. As far as stability goes, I find it easier to stand and paddle on an F16 than on the Penetrator, but it's very hard to save a tip on the F16, whereas on the Penetrator, if you don't go nuts when the board starts tipping over, it will right itself.

I think most people will pay some dues learning to paddle the Penetrator, but every time you get on it you get better and faster. Yesterday was a good example. I was pretty exhausted after spending from 9:00am to 12:30pm surfing at Kanaha, but I grabbed a quick lunch and jumped in to run the same course as the race last weekend. I was kind of loafing, but I blew past people paddling ordinary SUP boards like they were standing still. A guy on a 12'6" Starboard saw me coming and tried to give it a go. I passed him, fell in, got back up and passed him again with a few paddle strokes. It's a pretty cool feeling.

As to why other shapers aren't doing the same hull shape, some of them have tried it and didn't like the results. They struggled with stability and gave it up. I don't know whether Stuey just got closer to an optimal shape to start with or he simply stuck with it long enough to make it work. But work it does.

The bottom line is that what's going on in racing boards is a battle of elites. The best shapers and the best paddlers are doing new stuff every day. Mark Raaphorst, Stuey Campbell, Joe Bark, Bill Foote, the wizards at Hobie--these guys have literally hundreds of combined years of design and shaping knowledge, unbridled creativity and a willingness to put themselves on the line with every new board. We mere mortals get to play with the toys they make. How cool is that!
