Hello everyone Apollo is in position .... Too bad we couldn't work full time on this boat. I still have a month left. I don't know if I'll make it by the end of June. Hopefully well bye

An info sheet is provided at Bernd's site: https://www.ikarus342000.com/ECO520infosheets.pdf

Good day, I’m intrigued by the Eco 520 and have added it to the mix of possibilities for next winter’s project. Will you be making a study plan available? ?I’m particularly interested in mast,

Those photos certainly highlight the twist in the boomless main when sailing with wind aft of the beam.

Hello Thanks for the input. The Trismus shows a? nice adaption to the A-frame mast concept. The Voyager can be build of course with a center mast.. Patrick will do it anyway. What speaks for the

I think you lose some performance on any boomless sail, unless you can pull down hard right where you need to. Making the sails rather flat might help. Bernd has said that furling sails work well when

Hi Domenico Yes, we are doing very well over all, thank you. Your drawing looks similar to what is in the plans, so it looks ok to me. It is a big thing to be an experiment, though. Of course the wood

Thanks Cyril My idea was right you anticipated me ... ;-)

Hi Patrick how are you? I hope well.. Fot the construction is an idea. Is a mix of glass and carbon. As you see in the photo the cross bars are in an oval form like the mast and fixed on the mast.

@catamaniac:?I have researched a bit the issue of battened main vs furling main. It seems, that there is no conclusive answer to which is better :-) It all depends on intended use of a boat. Of

Hello Domenico It might be good to make the top the same as the bottom, not smaller, as it will need to be just as stiff as the rest. Will you add carbon or just glass? What will you use for the cross

Hello Patrick I tought about this idea to build the mast for the Kd122 italy with this design As you see the two mastes have an oval form. The base is bigger and the top is smaller. I think is the

Aha, weight is 29kgs. S?awek

Here in Poland (producer) composite mast/ flagpole 12m, lower diameter 145 mm, upper diameter 65 mm, with 10 year guarantee costs 263 USD.?Transport- Poland territory- 120 USD. On the EU no taxes,

DIY carbon A-mast. How realistic that sound? In Australia we have number if flagpole suppliers eg. http://flagpole.com.au/flagpole-range/flag-pole-sizes/12m-external-halyard/ Problem is the are

Yes, he does. ?But I think there was some issue with the stiffness at the top if you use tapered flagpoles as your base material. I decided on a center mast, so Bernd drew me a center mast instead

Patrick,Does Berndt provide informationj/design for the A frame mast in the plans?CheersPhilip Malan
