Sliding Rigger plans

[garland reese]

Wasn't there a somewhat recent thread mentioning one who had developed a plan for a slidiing rigger? I'd sure like to find a scheme for building a sliding rigger... pondering a shortish rowing boat these days.
Thanks to any who might have some thoughts.

Graham King's Kingfisher plan has a plan included with the boat plans. You can buy the Plan from Wooden Boat.

Avoid the Glen-L one, its crap. Built it into a boat using some of their specs, and noted that the runners corrode, the wheel setup is high maintenance, the retainers are unimpressive, and overall its heavy.

Build the platform, buy a seat/carriage, and mount the rails in a traditional boatbuilding fashion, you will be good to go.

I'm looking for a sliding rigger drop-in type design.... not a sliding seat. I can easily source sliding seat parts, and fabrication of riggers.

I would like to do a drop-on style sliding rigger unit..... I just don't know how to best go about such a design. I've never seen one, except pictures. For short boats, this would be a supreme way to go, for sculling.

I thought I'd read in some thread here, where someone had posted they'd made some plans for a sliding rigger.... I could have just been dreaming, I reckon.

[oznabrag]

I'll try this one more time.

From the thread I posted for you earlier, post #5:

There are more references in that thread, but if you want to make your own, you're on your own, most likely.

Best of luck,

I'm familiar with the virus boats. The concept of sliding riggers, as opposed to sliding seats, has been around since the lat 1800s, I think.

In modern times, I reckon, it has missed out on the mainstream of sport rowing, though far superior to the sliding seat setup. In this case, competive rowing has seemed to have squelched the mainstreaming of a superior design. Unfortunate.

Thanks to all,
Garland

Well Garland, that thread was my first exposure to the concept, and my good Girl paid her way through college in a shell!

Another thing I learned from that thread is that sliding riggers are illegal in the mainstream rowing community. That is just too bad, IMO.

It looks as if one of the major advantages, as you are aware, is the smaller length per rower required. 10 rowers in the same length as an 8-rower boat? :eek: WOW!

[garland reese]

Yes, they work great for shorter shells, and they are superior to sliding seat rowing. My girls rowed as juniors in H.S. My oldest had a part scholarship to university, but opted for the Marine Corps instead.

The sliding riggers having been banned, is, I think, part of what has kept them out of the mainstream marketplace. Rowing, in the grand scheme, is sort of a fringe sport anyway. Not a huge market for shells.

Good to see you., Its been a while. I do not know if this is of any value to you. If you mean that the rigger moves to adjustable positions or pivots when being rowed like the foward facing setups that have the double pivot rigging.

But I thought I would put it out for you. This is all portable and adjustable. It even comes with an electric motor and stick steering just in case any old guys gets tired. If you look closely he even used hemp to wrap his electric cable.

Send a mail and give us an update sometime.

Virus Boats seem to also have a home build sliding rigger wood design you can plans for.

http://www.rowvirusboats.com/images/seadog/shell200_6.jpg

perhaps the plans also include the neat sliding rigger. Looks fairly straight forward in the pic.

A pal and I are just trying to build two Oughtred Snipefish and we are hoping to build sliding riggers for them.

i am finding very little about sliders on the net. i need to build two. i posted some photos of the rather simple but beautiful performers from the south end rowing club stable boats (just search this forum for south end rowboats if youa re interested to see). i was considering the glen L kits. can anyone else weigh in?

[keyhavenpotterer]

The Clovelly Scull also has a sliding rigger.

http://www.clovellysculls.co.uk/c-sculls/proto-three-750.jpg

http://www.clovellysculls.co.uk/

Looking at the two pictures, it seem to be the common design features are:

build a rail track as per sliding seat

build a running platform as per sliding seat

make a "bent" rigger which adjusts for the distance that the position of the platform is further forward than the correct position of the oarlock mounts, and

raises the oarlocks to the correct height whist clearing the gunnels.

mount a "bent" crossbrace on the mounting platform

make sure the seat holds the occupant with some security - note the seat on the Clovelly Scull.

Thinking through the list in the above post, I realise now the main difference when installing a sliding rigger instead of a sliding seat, is that the sliding bars are installed further back in the boat, under your feet rather than under your posterior. Obviously I guess!

Well on the Snipefish the whole sliding assembly is dropped onto to the only two frames in the hull. These are already in the hull as shown below. So looking at the drawing will we simply put sliding wheels under the foot brace, attach double curved outriggers to that moving foot brace and then fix the seat? I am guessing the seat should be positioned at the most forward position it would have reached, and then the sliding feet brace has the correct range? If so, it seems that the rowers weight might be further forward than with a sliding seat version, by the amount of half the designed seat movement range.

The fast fixed seat boats I'm familiar with are sprint kayaks - and in these the fixed seat is adjustable over a range of 6 to 8 inches - and people care about where in the range their seat is positioned.


Is the foot-brace to rigger wing distance fixed or adjustable?

Brian

Good point. Is there a close-up photo of the seat somewhere on the Clovelly site? I don't see one.

Piantedosi make sliding riggers, here. http://rowingrigs.com/slidingrig.html, Looking at that it should not be that hard to build one yourself if you cant justify the cost!
Out of interest i recently met a Gentleman who is heavily into the fine boat rowing scene in the UK, the sliding rigger had won the world championships convincingly & was set to take over, it was banned by FISA the international rowing organisation. My contact was at the meeting that banned it, the reason given that it would cost too much for smaller countries to change over. In reality it was the eastern block & others that ganged up to stop it along with a heavy dose of stick in the mud conservatism.

Thanks for pointing that out. Our simple concept is to begin with two stainless tubes mounted on the two frames. As per this Finnish fast rowing boat

http://www.puuvenepiste.fi/images/PS1-persp2.jpg

Since we will not be quite sure of where everything should be, this idea of adjustability is a good one.

Imagine 3 small carriages, one for your feet, one for the rigger and one for the seat. If each carriage could either slide or be clamped in fixed position. you would have infinite adjustability.

Sliding seat, sliding rigger and fixed seat fixed rigger. Spacing adjustable and also possible to link rigger to foot brace.

Think I had best go and lie down!

Sorry to seem cryptic.
According to the Rowcat (http://www.rowcat.com/)site, "It is, currently, not possible to buy a ROCAT.".

[P.I. Stazzer-Newt]

Essentially Rowcat went bust - I suspect that this is another case of "The best being the enemy of the good" - they went shooting at perfect, rather than fun.

.

After months of frustrated waiting, I finally recieved a Piantedosi RowWing from one of his dealers. Unless you have access to a very well equipped machine shop and can do custom fabrication, your efforts won't come anywhere near the design and solid construction of these units. They are a marvel of well executed design and engineering precision. And I'm saying this after being really put out by Piantedosi's dodgy business practices. Six bills is really quite steep but worth every penny. Beg, borrow or embezzle to get one. You won't be disappointed.

BTW, does anyone know the story with Mssr. Piantedosi? He's obviously a very talented designer and engineer. Very mystifying why he would let his business deteriorate to the state it did. Fortunately, some other parties have stepped in and reintroduced some order and discipline. I sincerely hope they thrive in the future.

As I understand it, one of the german rowing coaches (Volker Nolte) was deep in the development of the sliding riggers, just prior to the FISA ban.

As it turns out, Volker's now a rowing coach at the University of Western Ontario, in London (Ontario). He's worked with our local club a few times, as he'd coached the Canadian men's lightweights back in the 90s when one of our club members was on that squad.

It might be that Volker could share some info with you directly - especially regarding things like setup etc. He's phenomenally persnickedy about setup in conventional sliding seat boats ... I can't imagine that trait wasn't there back in the day. Probably Volker's e-mail address can be found by trolling University of Western Ontario websites.
