S2E50 Designing and Building the Bilge Keels Part 1 || Wave Rover 650

[@cerealspiller]

Thanks for the peek at the design and manufacturing process for your keel! The marriage of machine and computer continues to amaze.

[@RoversAdventure]

Thanks but I have to admit that it's all well above my pay grade!

[@bernardszirth9665]

WR650 just got it’s wings- before we know it it will fly away the horizon new adventures! This episode somehow makes it even more amazing. Thanks for sharing as always :)

[@RoversAdventure]

Thanks Bernard, I really got a lot of great help on this one.

I built the same type of keels for my 22ft boat around 30 years ago.We made sure they were the right shape. We filled them with around 100kilos of shot blast each and welded the hole shut. I sold the boat about 2 years later. Fast forward 25 years and I see her on the hard on the south coast of England. The keels were like new. Great job you did with yours

[@davidrumsey3180]

Our Denis Ganley designed steel cutter has a keel that is made in a similar way: NACA 0014 profile, 1" thick steel plate bottom profile, internal vertical webs, round pipe as the leading edge.. The performance is very good, regularly embarrassing larger yachts to windward, and the strength of the keel was proven a couple of times... So I am pleased to see that you have chosen this method of construction. Paint them well and weld a small anode to each keel and they shouldn't give you any problems. On our steel yacht, the underwater steel parts did not give us any corrosion problems, even when paint was chipped (e.g contacting coral at 6 knots, or when the boat ended up on a rock breakwater when a "Professionally maintained" mooring lost a shackle pin)... as long as the anodes still had some zinc left. If you use lead for balast there might be room above it for tankage??

You have my attention and subscription. This is very exciting. I have two "sailboats" sitting in my backyard here in New Hampshire right now ~ both with major "fixing" going on. All aspects of this project are gold. I've heard of the "Bilge Keel" but here you are building Two ! Wow! ~~~Best wishes. /Thank you for this project !

[@sailoutofagarage6212]

I like that thought about low tech builders as well as fully equiped workshops.

[@curtishill6490]

👍 been waiting to see how this is gonna go💯 had me worried on Thursday 😁good to see another video💯Thanks for getting into the ins and outs of this design!! Stay safe and healthy Mr &Mrs Rover🙏🙏

[@RoversAdventure]

Thanks for understanding on the delay. The house build, as important as it is, is cutting into my boat building time.

[@normfacey104]

There’s a lot of dreamers, not so many doers out there…..it’s awesome to see a channel where I believe you’ll actually set sail and cross oceans. We believe in different boats, but I respect your choices….and envy you your cruising future. It’s awesome out there! Make sure you visit northern Tonga - best cruising in the world.

[@ArcticSeaCamel]

This is exactly the method I’m planning to use to make my bilge keels! Great to see the process before I do it… 🤪

[@robinhodgkinson]

Nice job. My tri plans came with dxf files for the aluminium folding arm components, etc. Everything fits like a glove of course. Just love cnc! Computer precision. Easy.

[@Itssmial_Ova]

Another brilliant video, It's really exciting seeing it come along.

[@RoversAdventure]

Many thanks!

[@howtosailoceans1423]

Wow, cutting steel by a robot with a squirt gun. Who'd a-thunk it.

[@hecdc305]

Very interesting engineering.

[@prof.heinous191]

Lots of useful info here! Naca 0012, note taken. Hoping the angles offset from parallel and vertical are covered along the way sometime!

[@RoversAdventure]

Noted!

[@wellsgb1957]

Excellent stuff 👍🏻👍🏻

[@RoversAdventure]

Thank you! Cheers!

[@brucehauan9000]

Can you buy a kit with already cut keel components?

[@bikebasket9594]

Very interesting video. Thanks.

[@RoversAdventure]

Glad you enjoyed it

[@charlesbreaux5475]

I would like to know the keels are not asymetrical. Plus, why was there no wing keels added. In addition to combating the tip vortex wing keels would provide a more secure platform for grounding

[@RoversAdventure]

Very interesting ideas and perhaps another builder will run with them. It was always my intention however to keep this prototype as simple as possible.

[@charlesbreaux5475]

@@RoversAdventure Hey thanks for answer. I just couldn't figure out why you would go through all that trouble to design and fabricate the keels and not include those... there used to be small fleet of junks 3 or 4 in the San Fran Bay (60s 70s). Almost bought one of them but ended up just hanging out and sailing around with them. Had a number boats but never realized my dream of creating my own Wave Rover with a junk rig. Good on you...

[@mattevans-koch9353]

Those bilge keels are going to look like whale fins under the water Alan. Hope you don't cause any amorous advances by other whales. What do you think the final draft will be with the keels once fully prepped for sailing? Best wishes to all.

[@RoversAdventure]

I think the draft will be about 3' 3" . Interestingly, when I sailed across the pacific in my first boat (a bilge keeler) I had a pod of pilot whales swim under me several times. My bottom paint was black, and I could clearly hear both the whale song and the clicking of their sonar. A very special occasion indeed.

[@Itssmial_Ova]

Will you include the revised keel plans with the design we can purchase? I'm really keen on building my own Wave Rover, I've just returned to employment, and the sailing club is teaching me the lines.

[@MaShcode]

Huh. So the keels will be filled permanently with lead? Or is the intent to add ballast as needed along the length of the hull? I always felt glassed in lead keels were inelegant and prone to failure requiring regular checks.

[@RoversAdventure]

after the lead is poured in I will be welding them shut.

[@gordonstewart8258]

Just like the plastic models I built when I was a kid.

[@randomtraveler3363]

Fantastic. Nice that the files will be available to other builders. Will there be an additional cost or will it be included with the construction plans?

[@RoversAdventure]

That's a good question. The building plans come with a well thought out keel. This is a different approach but the end result will be the same. We will make this available at a small cost if builders want to take this approach. The cost will offset the design work

[@DAVIDMILLER-nc9vo]

I would have though that the steel was only an outside frame into which molten lead would be poured.

[@RoversAdventure]

Correct, lead will be poured into the keels at a later date.

[@Garryck-1]

Algorithm Booster! ⛵

[@Bob-jn1fx]

I would love to see a $500 plasma that cuts through quarter inch steel and exactly how many zip cuts do you guys think that would take

[@jimmathieson9549]

Wood and fiberglass bilge keels would be way easier for me to build ,far less money which is critical for this senior.Steel rocks for sure if you can afford it.cheers

[@RoversAdventure]

Plywood/fg is robably the most economical boat build out there.

[@romuloaugusto3003]
