Hi Michael, That's funny , I am happy with the start

 

Hi Michael ( MEDDO ) Sailing is amazing ( on any boat ) I agree , This one is pretty extreme

 

Best Rgards,

Hi Crckers,  I see that you are a fellow Spud ( for those that don't know , if you live in Idaho you are a Spud) Welcome aboard. I will be trueing up the frames and installing them today. I just discovered these boats a few weeks ago . it's nothing like I have ever built before , Should be fun

 

Best Regards,

Pete

I wonder how these boats would look without all the fractured advertizing all over them, just simple colours to accent their shapes and high tech materials. I think they would look far superior. but that is just me.

 

On the other hand imagine a 1930's J class yacht covered in "Pears Soaps", "Colemans", "Indian Motorcycles" or "Liptons"

 

Somehow I just can't picture it!

Hi Michael, Advertising on a J-boat, does not work for me . I am going to use the same Blue on the Hull that I used on Stars & Stripes, with a White Deck , Yellow accents and Flat Black on the Spars , Rudder Blades and Keel , She should look pretty good Color wise .

Looking good already. Makes it look so easy the way you are building this boat.

 

Seems building these boats is a hit as there are several sites that show others building them as well.

This Aussie has a beautiful build log from the "Volvo 70 Ericsson"

http://www.rcuniverse.com/forum/rc-sailboats-89/8076736-volvo-70-ericsson-build-log.html

Current Built: Zeehaen 1639, Dutch Fluit from Dutch explorer Abel J. Tasman

Many people believe that Captain J. Cook discovered Australia in 1770. They tend to forget that Dutch mariner Willem Janszoon landed on Australia’s northern coast in 1606. Cook never even sighted the coast of Western Australia).

Thank you Marc, I will have to look into that , I like the look of the Ericsson Boat , she's pretty sweet

Another great day with the Boat ( day 2 ) I started by making the Keel slot and Mast step in the Back Bone, I then trued up the frames and installed them. Next I made the deck and installed it. I then faired the frames for about 3 hours and started Planking ( my favorite part of the build ) Iinstalled the first 2 rows of planking, She's going together like Butter. I glued everything together with Titebond 3.( it's Waterproof )  Next will be to finish planking the Hull , and get her ready for West System Epoxy. She's an Amazingly fun boat to build . Here are the results

Hi Pete. Extreme sailing with an extreme boat. When I look at your photos of the hull, i can't help but think 'who thought of designing a boat with a massive flat and broad rear, coupled with a knife thin bow!' Seems like it'd never work, but, hey, obviously it does because, as you've said, these are extreme racers. Fast and nice!

Posted

Thanks Geoff, I try not to disappoint , She's practically building herself

 

Hi Omega, it's a very intresting design, it looks like the front half of a larger boat. It's alot easier to Build than an America's Cup Boat . It's almost a hard chine with a round bilge .

 

Here is a shot of her upside down so you can see the Keel slot , I also brushed on Titebond 3 to the under side of the deck and frames

 

Best Regards,

Pete

Pete,

 

I just stumbled on this build. It will be a lot of fun to watch (and build)!

 

I'm sitting here, thinking about making a boat like this RC, and wondering what a functioning canting keel would do on the model. Unfortunately, I don't know how the canting keel and planing hull scale down on the model, but it would be pretty cool to get the RC model on plane!

 

Both the VOR and Vendee Globe are way beyond my meager sailing abilities, but they're fascinating, regardless. If you're interested, a good book on the Vendee Globe is Godforsaken Sea by Derek Lundy, describing the 1996 Vendee Globe race. I enjoyed it a lot.

 

Have fun! We will!

 

Thanks,

 

Harvey

Hi Harvey, I just stumbled on to these Boats a few weeks ago, I have seen rc versions of the Volvo Boats,( very impressive )  However they do not have the Canting Keel, Mine wont either. she will free sail with out RC ( Like my Herreshoff Buzzars Bay ) I will be doing an RC Boat next ( BMW ORACLE RACING USA-98 ) It's good to hear from you again

Pete

I’m with Omega1234, that design is all wrong and can’t possibly be fast.  But hey, it’s hard to argue with success.  It will be fun to watch her sail.

Today was another Great day with the Boat. I started by pre soaking my planking material 1 hour before start. I then finished planking the Hull, I am pleased with the results. this Boat has been extremly Fun to build , ( I would recomend it ) I then started Fairing the Hull, I will finish Fairing the Hull in the morning . She's coming out right on the numbers . Here are the results

Pete,

 

Looks good!

 

One thing I'm surprised by is the hard chine on the hull. I had always thought the hull was completely round.

 

I'm curious what the hard chine does. Additional stability (along with daggerboard) when heeled?

 

I'm also curious what the optimum heel angle is for speed when sailing close hauled. Perhaps the chine adds to WL length at optimum heel angle.

 

Thanks!

 

Harvey

Harvey,

 

These boats are all about creating maximum stability. This quest for stability gives you more hull area (and resistance when upright). They have however so much sail area that this is only a real handicap in light and upwind situations. The rest of the time they use their brute power to plane to the horizon!

 

To understand the chine, you think of a boat much wider as is practical or allowed by the rules. You get a flatter more powerful shape. then you chop off the parts of the hull that are not allowed. You end up with a shape that acts as if it was a wider boat.

 

As these boats are optimized for ocean racing they do not sail upwind with fine angles often, they sail a bit lower under the assumption the the wind will change anyhow in the next day(s).

 

The topspeed of these boats can reach almost 40 knots with an average of 24 knots!

Hans,

 

Thank you for your explanation, although I have to admit, it will take me some time to comprehend it all. I hope you don't mind if I throw out a few questions and assumptions to get on the correct track.

 

I'm used to thinking of chines as a (kind of) stability point at a certain angle of heel. In the case of an El Toro dinghy (which I used to sail) and a Star (which I haven't sailed much), the heeling angle when the boat is on its chine is a more stable point than most heeling angles. Is that correct?

 

I also remember that increased heeling angles (on displacement racing hulls) provides a longer waterline, which increases hull speed (which is why I thought racing sailboats of the 20's and 30's had such long overhangs). But waterline length on a planing hull doesn't help (IIRC), because you want to minimize wetted area.

 

I looked up some of the measurements of the Open 70's. I see the beam is 5.7m. If I understand correctly, is the basic hull design much wider than this, but surfaces are created to cut the beam to 5.7m, thus creating the chine?

 

Please note that I'm not an NA or Marine Engineer, but I've been fascinated with sailing hull design for a long time. Generally, I know just enough to be dangerous :o

 

Thanks,

 

Harvey

Posted

Harvey,

 

On light displacement boats (with a wide a...) you want them to heel to minimize wetted surface. I don't think that a chine is a sudden increase in RM (righting moment) but you want the boat to have the chine on the surface. The water will flow of the chine with enough speed.

 

Increasing heeling angles does work wonders with long overhangs as you wrote, but these modern boats are vertical ended so not much change there.

Waterline length on a planning boat does not help, but as you are also not plaining, a longer boat will usually be better.

 

Simplified you explained the design process, but i think that the tooling is now evolved and more specialized, as are the architects.

 

I am not a architect either, but I sailed a lot on modern racers and now sail a proto Mini Transat 650 solo. These Transat boats could be seen as mini V70's with canting keel, asym. daggerboarts, waterballast, twin rudders etc,but then sailed solo!

 

Hans

Than's Geoff, Planking is one of my favorite parts of the build, I am pleased with how it turned out

 

Thank 's Harvey, She's starting to take shape, I did find an RC model with the Canting Keel made by Stockmaritime here is the link to the site :n http://stockmaritime.com/modellboote/vo/allgemein.php?lang=en_GB&id_bilder=393163

 

Hi Michael, I am happy with the colors that I have chosen , and can't wait to see her in those colors

 

Thank you Hans, For providing a great wealth of knowledge on these Volvo Boats, I appreciate it , the Mini Transat 650 looks to be a fast boat, and looks like alot of fuin to sail.

 

Best Regards,

Pete

Harvey,

 

Funny that of all the mini pictures available you showed this one! 713 is the old boat of 2 very good friends. Later (in 2011) they where the first married couple to sail the Mini Transat Race (each solo in their own boat!), a very special achievement.

 

I hope to make a model of my own mini 595 but I have some full scale projects for that boat in progress!

 

Pete, the mini is a lot of fun if you can handle it. Upwind they are fast for a 6.5m yacht, but reaching and running is where the fun starts. They have up to 135 m2 sail area running for a 700-800 kg boat!

 

I like your Volvo model, good progress!

Today, another great day , We had a thunder storm and lost power early this morning , so I spent the day getting the Hull faired. The boat is actually a little more complicated than originally talked about .I then decided that I would do somthing different with the cabin , I made a mock up out of paper once I was happy with it, I made one out of Basswood. I then started making the Bowsprit , ( I taped it together and to the boat for the pic's) The cabin is not attached and is positioned for the pic's. Here are the results
