To get or not to get daggerboards, that is the question. It was one we had to ponder for weeks on our HH44 Catamaran. Especially because of this other option called winglets.

Curiosity 2 is a hybrid electric HH44 Catamaran splashing late summer of 2023.
The biggest benefit to hanging around such a bespoke boat factory is the unfettered access to some of the world’s leading experts. Because it seems there are new specialists coming in to collaborate on different boats every month.
And lucky us, we managed to make friends with Erik Berzins while he was visiting the factory. He is a Yacht designer and all-around incredible engineer at Morrelli & Melvin. If you know who M&M is, then you already know they are regarded as some of the best designers in the world. And wow, we learned heaps about all things sailing while carpooling to the factory and exploring on weekends together.
He designs and manages a wide variety of projects including some very cutting-edge multihulls with mighty fancy appendages (daggerboards, foils, winglets, rudders). And considering we wanted to make a video explaining why we choose NOT to get daggerboards…we knew he was just the person to help us break down exactly what all these different appendages do.
To get or not to get daggerboards, that is the question. And it was a huge, difficult decision we had to ponder for weeks. Especially because of this other option we never knew about called winglets.

I dont blame him top loaders are expensive so I hope he finds one to fit the corner where they have chosen to fit one if she lets him have one which I think she has as the blowback from subscribers including me would be massive I am just wondering whether it is a mutual decision to go without daggerboards to me it makes sense to go without them I would do the same if I had a choice as dagger boards are expensive and you have more safety with the wiglets as it protects the rudder as they have said and it makes the boat stronger to boot so it's a win-win.

As an Aussie, we were so impressed when Australia 2 won the America Cup 1983, back in the day. The big advantage they had was the design of the keel with a bulb and winglets, by Ben Lexcen, which started the tradition of winged keels.
@johnnylightning1491
@johnnylightning1491 Год назад
I think you made the right decision on the dagger boards. You don't need any added complexity and failure points in your boat for what you do. I guess if it takes you another day to get somewhere it's a small price to pay for having to sit on the hard for months to fix a dagger board. It goes along with the KISS principle which in most things in life is a very good rule of thumb. Keep the good stuff coming guys and happy anniversary.

Dagger boards are hardly complex.
@pioneer_1148
@pioneer_1148 Год назад
That doesn't really make much sense. Avoiding dagger boards does avoid some complexity but not much and pretty much anything which will break a daggerboard will also either break or heavily damage a standard keel. Additionally, while HH boats while extremely impressive from an engineering standpoint they are definitely not KISS. They're more or less comfortable raceboats. There's absolutely nothing wrong with that as a boat, but as a cruiser they're terrible. Everything is hyper-digitalised, made out of carbon-fibre (which while an amazing material takes damage extremely poorly) and there is very little in terms of back ups. A lightning strike and/or collision with a container, whale or uncharted ground will make the boat extremely dangerous and will very possibly sink it. All these problems are present to some extent in all modern cat manufacturers and the way keels are built for almost all modern monohulls makes them extremely dangerous for cross-ocean sailing too (kraken is, to the best of my knowledge, the only manufacturer making boats with an integral keel). However, HH is a particularly bad offender, they build some of the least durable and worst suited boats for cursing and market them for that exact purpose.

The winged keel, if my memory serves me correctly, was introduced to the sailing world in the American's Cup race in 1983 onboard the Australia II 12m boat. The keel was designed and tested in secret by Ben Lexcen in the Netherlands. Great Aussie/Dutch innovation!

For his 1983 challenge, Ben Lexcen revolutionised sailing yacht design with the creation of the winged keel. Described as 'upside down', the keel lowered drag, made the boat more stable and manoeuvrable, particularly in tacking. Cheers guys live your videos,Tony Brisbane Australia 🇦🇺

If you sail around the world with the trade winds, a dagger board would be in the up position most of the time and give no advantage. I think you made the right decision. I'm looking forward to a race against Parlay Revival. When winglets were introduced into the Americas Cup by Australia, it was a way to outwit the 12 meter rule. When the boat healed over, the winglets gave the boat a deeper draft than the boats without winglets, creating an advantage upwind. It was a brilliant move by the Aussies.
@pioneer_1148
@pioneer_1148 Год назад
You're right that cruisers will have the daggerboards being in the up position most of the time. However, that doesn't mean they won't be providing an advantage. A dagger board in the up position produces almost no drag as opposed to a minikeel which, even with the best designs, will still produce quite a lot of drag. As for the winglets, to the best of my knowledge you are right about them being designed for and introduced on Australia II, however, the advantage doesn't have anything to do with outwitting rules or any particular length, it's simply a more efficient design for high speeds.

Another wonderful feature of winglets is that they act like a shovel. So when the boat does run aground it digs in and anchors you to that spot so you don’t have to worry about going anywhere while you wait for a tow boat service to arrive and give them all your money!

The main considerations for me were speed and safety, Dagger boards are safer when the shit hits the fan for real, pull them right up and have nothing to trip over, can not do that with mini keels. Large beam as well. I don't have an escape hatch.
@ebreevephoto
@ebreevephoto Год назад
I look at this way... If you get dagger boards you have to know how to use them, and to be honest it adds complexity to every movement you make. I agree the winglets would be my decision as well. I would rather just know my draft is X and cruise into an anchorage and chill....

Jason and Nikki, thanks for digging into the technical in a way that few other content producers do. You've kept the topic narrow, invited expert opinion, kept to to the idea that it is all personal preference and then added a nice dose of local color. The average viewer does not have the time or resources to go pick apart each of these topics to this extent. At the end of the day, despite all of the eco this's and thats, you've still got one of the most impressive pieces of plastic in the ocean, and you're not sanctimonious about it.

Coating a dagger board with bottom paint while on the hard can be quite the procedure when they are 12 feet long or longer! Also, one would have to worry about barnacles and such jamming them in the trunks.
@elysiumsailing
@elysiumsailing 11 месяцев назад
I agree, you made the correct choice here. The other issue with dagger boards not mentioned is that because they have to make them so strong to withstand those forces constantly that when you do hit something with one, you can end up with a hull breach because the dagger board case cracks which is an even more scary situation. I have a catamaran with dagger boards, and another with mini keels, you can guess which one I use for cruising!

Well having had to sail upwind beating into 6-8 foot seas and 25 knot winds for 14 hours due to a medical emergency, I can say I’m happy with our choice of daggerboards. Allowed is to make landfall on a single tack, vs spending 5 extra hours tacking back and forth. I do understand the advantages of keels though and it’s a good choice for many as well. I’d just get tired of all the questions at anchor of people asking where the daggerboards are : )
@kjkayjay

Not being a sailor, my first thought in a medical emergency would be to kick on both of the catamaran's engines. I'm assuming that would supersede any pro or con of daggerboard vs mini-keel?? I have no idea.
@kirkb3473
@kirkb3473 Год назад
@@kjkayjay well it’s a good thought and could be the correct answer sometimes, but in this particular case a performance catamaran with daggerboards can sail faster than it could motor in the direction needed. For the most part performance cats sail much faster than they can motor unless it’s extremely light winds coming from the wrong angle. A lot depends on sea state as well, there’s no single correct answer, but it’s nice to have a boat with the ability to point as high as possible. Is it worth the extra money, complexity, and risk of damage, that’s for each person to decide for themselves…it’s all a series of compromises.

A super interesting video this week and a really great interview with someone who actually isn't in sales and knows their stuff - looking forward to seeing Jason going upwind with his hair on fire or maybe a Katniss Everdeen moment for Nikki 🤣. I really would like to know if the winglets are providing lift why are they symmetrical or do they not behave in a fluid like in air so angle of attack is more important? The other question and you sort of answered it is would simply putting on one electric motor make the real advantage of daggerboards in light wind irrelevant - you can effectively increase apparent wind with a bit more air speed so sail higher anyway and a small amount of added energy oversomes any drag deficit of the stub keel and improves lift efficiency, also as the motor is off-centre you reduce leeeway by adding a rotation vector to the hulls so improve vmg.

Sunday Morning Coffee with the "Wynn's", nothing better than this! What a learning curve on keels, dagger boards, efficiency, etc. It is so interesting to learn how much sailing has turned in the last 15 years. The only thing is when your guest Erik was discussing the wing tips of an aircraft that was a really silly remark, they are not just for aircraft to fit together. They serve a far more important Purpose. They improve the efficiency of the Aircraft! Just like your illustration at Min 6:12 said. This aspect has been in use in Aviation for at least 50 years. When I worked at Cessna Experimental Twin Division we were just incorporating it into the Citation 500 Jet and their brand new Designed twins Piston Aircraft. Glad you cleared that up.

@dansegelov305
@dansegelov305 Год назад
You're definitely right, but regular wings loose effective lift at the extremities due to turbulent vortices disturbing the flow. So a 30ft wing will loose useful area in the last 2-4ft at the tip, effectively making it a 26-28ft wing. By moving the vortex to the tip of a winglet, you retain the full 30ft for lift generation, making the whole wing more efficient. I'm guessing that this is what the guy meant.

@BrianRhodes9763 Год назад
Great video, I was impressed that I actually understood 90% of what Eric was talking about especially the comparison of the winglet on the keel to the winglet on an aircraft. On an aircraft wing there is what's known as wing tip vortex (a swirling motion in the air as it travels off the end of the wing or wing tip), wing tip vortex creates more drag, more drag equals less speed. The keel acts the same way, it creates a vortex at the bottom of the keel, by adding the (horizontal) winglet, it prevents the water from rolling off the bottom of the keel and creating the vortex type flow with the water (I think that is called fluid dynamics, but I am not sure). Again fantastic video, and great choice in adding the winglet.

We had a wing keel on our monohull. At anchor I noticed wonderful breezes coming through from the cockpit and thought - that's not right....we should be bow into the wind. Current and wind cause our anchor line to wrap around the wing keel. LOL. Another time in the Bahamas we ran aground in a remote area 3' from depth.....we sat firmly on our wing keel all night while the water drained out below our seacocks - never tipped and then as soon as we felt water lapping the hull we kedged and motored over to the depth. LOL! Fabulous lifestyle!

Happy Anniversary! I learned a lot from this video. As a non-sailor, I just assumed that catamaran == daggerboards needed. Really appreciated the interview/conversation with Eric, and the explanations by all of you.

I have sailed various cats without dagger boards nor keels, and they did upwind pretty well. It largely depends on the shape of the hull.

Sorry guys, but I can think of two downsides to winglets on your mini-keels: -More wetted surface area means more profile drag -Higher likelihood of snagging seaweed and crab pots

Thanks for covering this topic!! You made the perfect choice. You may or may not want to go faster (though I think you’ll go plenty fast), but I’ve never heard anyone wonder about whether they’d like to point better or more poorly. No one says, “ya know, for $5K, I just really would rather have worse VMG for all those years of sailing”. Very excited for you both!

Having no knowledge at all about this subject before watching your videos (which have been IMMENSELY informative and interesting; I really enjoy the instructional aspect of your channel) I remember your original motivation to go performance and I think that your moderation of that with the mini keels over dagger boards seems a well considered choice.

Erik was good at explaining various aspects of appendages. Your own explanation discussing your decision making was very informative and made the issue much clearer. I have a boat with asymmetic foils and lifting rudders, I like the light weight and the ability to go into much shallower water. B M

Something interesting I learned recently. The area where the Winglet connect to the keel produces quite a bit of drag. The drag is caused by the tight angle. If the put a radius in where the angle is this reduces drag. This was figured out on airplane wings and it was about a 10% gain in speed and a 10% gain in fuel economy. I don't know if this is the same for keels but the drag will still be true. You should ask. Now the down side. There's always a trade off😊 you lose a little bit of wing area with the radius.

I often wonder what the effect would be if the entire keel is curved in, or for complexity's sake, angled in, similar to how straight dagger boards will be angled in. Seems like you can get a little more surface area to bite with minimal draft penalty.

For my 2cents, You guys are cruisers, as you mentioned, and if you find yourself solo in the middle of the night and a blow pops up, the dagger boards are one more thing to possibly get wrong/forget to adjust. Fixed was definitely the right choice.

I agree with your decision . I don’t much about sailing but I feel you made the right decision. Sailing to me is not about speed but comfort and enjoyment and enjoying your time on the water. Why is everyone in a hurry. A few minutes doesn’t matter. Freeway mentality. I really watching you guys.

Great explanation of the mini keel. Another good reason for adding that appendage is that "winglet" is a fun word to say.

Excited for you guys and IMO configuring is an essential fun part of the buying/building experience. I know nothing about dagger boards, and yet your choice seems perfectly logical. The only thing I am sure about daggers are that that require two huge threw-hull holes…and for me less “holes” in hull is better. 🤠

Live aboard a Gemini sailing cat. Has retractable center boards and retractable rudders. This arrangement allows the boat to be set on sand and dried out if necessary. Have never done this intentionally, but a couple of times accidentally. Being a shallow draft boat I regularly take it into skinny water (because I can) mostly to find anchorage space where others can't go. Consequently occasionally bump into things sticking up from the bottom. Luckily, never anything as solid as a large rock, and never while under sail (harder to stop). Each encounter resulted in a little noise and the board or rudder just pushing up out of the way. Never any permanent damage only scratched paint. I am a cruiser. The Gemini is NOT a racer, so it fits me perfectly. Just my two cents😊

You made the correct decision, I have a monohull but with a wing keel 4 foot draft, the keel performs better than most fin keels, but let’s me get into places, that other boats cannot get into. Under speed it really improves the handling greatly, only downside is lobster pots. Never had a problem fishing catching lines.
