One Metre trimaran "Box-on-Steroids" foiling

[@donb4138]

I keep watching this one, you make foiling look way to easy.

[@w.j.bendellr.c.flying.1037]

When is too windy to fly.🤔 I think we got something here🌴😎🌴 oh and by the way great video.⭐️⭐️⭐️⭐️⭐️

[@InYourDreams-Andia]

So cool! I noticed on full scale multis that they have their sails contact the hull, sealed against it by pressure and sail design..I think this concentrates thrust as low as possible..I'm gonna try this on my lunchbox MkII prototype...I'm nowhere near foiling yet, you have given me great inspo tho!

[@smudge6831]

Who is watching this after seeing the AC75s? Trimaran versus monohull, however many similarities when looking at foils

[@geraldharper330]

Nothing is more fun than just messing around with boats....even RC ones...

[@zbeekerm]

Performance typically goes up with increased wing loading (efficiency turning radius, etc.) but the trick is getting the vehicle to take off. Therefore I’m not surprised that the smaller rig is doing well. Also, as you noted, lower heeling moment is always a nice benefit.

[@berniestorr1202]

Hi could you show how the cat is set up out off the water sometimes I Hadley see these boat up close, show how the foil an rudder is installed an rigging please.

[@PerthMini40man]

Ok will do next weekend

[@andrewdavies6273]

Absolutely stunning.

[@glowiever]

pretty fast too! nice boat

[@reckemroysrc3764]

Multi hull nut. Just like you 👍👍😎✌✌

[@Bongo808]

“Multi hull Nut” here... :-D My wife and I are past State Champion Nacra 5.8 sailors but that was a long time ago. What a great video... I love the Idea of multihulls with foils on RCs Actually thought of it about 40 years ago but technology just wasn’t where it needed to be then... I would like any additional information you can get out... do you have a blog or website where people talk about what you’ve done?

[@PerthMini40man]

Hi Bob (fellow multihull nut). We don;t have a website as we are build these in a garage in Mandurah, south of Perth. just for the love of the boats. My email is [e-mail]. If you send me a contact email I can send more details

[@davidho2977]

The NACRA 5.8 is a pretty impressive boat. Never sailed one, but it will outrun my H-18.

[@utube8246]

Hi there very cool! Best performance for an RC Trimaran I've seen are those you have built! Hypothetical proposal here: would you be interested in collaboration on an RC Foiling Monohull as well as a larger person carrying Trimaran in the future?

[@captainsirjackchucklebutty6147]

Langkawi? Were you sailing there?

[@jotham123]

question, those foils aren't actively stabilized or anything right? completely passive?

[@PerthMini40man]

Yes correct

[@davidho2977]

Impressive! What is the all-up weight? I thought on such a fast boat, you would need at least the main full battened. Have you considered a wing mast? Is foiling a hard balancing act? Subbed.

[@PerthMini40man]

Hello David. On the smaller rigs we use stiffer material for the sails. We have considered a wing mast but cannot work out how to make them sufficiently light to be of benefit, so instead we compromise with a large pocket in the front of the mainsail inside which we slide the mast. My using a fairly stiff material for the pocket we almost achieve a wingmast effect. it liek the current America's Cup monohulls with their 2-ply mainsails. Our boats are not the lightest, we are probably 2600gms with rigs, foils and batteries and electronics. The lightest boats in Europe are probably 300-400gms lighter than us, but we find that weight actually helps the foiling as the boat is not so twitchy in gusts. Our main aim is to have fun foiling. If you want to win racing round a conventional race course then we might design something different

[@geraldharper330]

Just amazing...

[@Ec130Rhine]

It be nice to buy the boat do u have a kit that come with everything to take it to a lake when it’s windy ?? How much this the boat $500?!

[@PerthMini40man]

Sorry it costs a lot more than that

[@joescmoe5225]

How much does this rc boat cost?

[@jasona.neverforgetfukushim647]

amazing I love sailing and foiling but have frozen water right now. I would love to build one of these and experiment/play with it. I watched almost all your videos and these boats have come along way over the last decade. Is there a forum of builders or where would I get plans? what would you suggest as the best place to start, to get into the hobby?

[@PerthMini40man]

Hi Jason The best starter kit can be found at www.rcsails.com. Their Firedragon is a good beginners boat. If you hunt around their website you will also find some free plans. Which country are you in?

[@jasona.neverforgetfukushim647]

@@PerthMini40man thanks for your response, I'm in canada, and I think I would rather go the plan route as I love building things from scratch. another question with your foils do you build in adjustment screws into the hulls to fine tune the angles, would love a video of how you setup and tune the boat and sails as watching the effects in your video is fascinating but to see the actual components and adjustments made to the boat to me would be more interesting...maybe consider it for a future video?

[@PerthMini40man]

@@jasona.neverforgetfukushim647 Yes we have M2 screws going into nuts epoxied into the cases for fine tuning the foil angles (sorry for late reply!)

[@CarkeekW]

smaller rig, less drag :)

[@PricemoSC]

cash in hand WTB

[@JoeOvercoat]

2:34 Personal Flotation Device, people. Wear your damn PFD!!!! It's not like they are Mae Wests, nowadays.

[@PerthMini40man]

Noted Joeovercoat but the lake is only 4 feet deep. They can - and have - walked across the lake

[@Tintin-dm4ym]

It’s a pond, hardly white water rafting
