Brian: ??? I will agree that the 860 is on the minimal side, but I'm not a family man, and sail single handed normally.? The voyager is absurdly huge for my needs.? My direction is less rather

Hi as a small multihull sailor (Duo480 Jigsaw) I am all too well of the drop in performance of a multihull when it is loaded up with extras. However I just day sail mostly, and yet carrying a motor,

Bernd: ??? I'm not at all what this is intended to mean..........

Andrew: ??? This is exactly the problem I'm wrestling with.?? Multihulls have limited load carrying capacity, and as Bernd mentioned I've been looking at some of Jim Brown's Searunners, and to

500 would agree with my measurements on the drawing I printed out. H.W. 5vxm3humhdre5xfzriflnuj5iyy6kfdtgw76wrrv@... [k-designs] wrote:

right, anyway with a load factor of 1 : 2 it is more as okay as customers who made and make ocean passages reported to me

Hi Andrew Thanks for your throughts about the KD 860 after your very negative end statement of your last letter. Multihulls are load sensitive of course, because ascelleration in a squall is there

It isn't right. At KD860 project it's 500 and 600mm

An RC propeller actually works very well in water. For decades the APC brand of RC propellers were the choice of human powered watercraft not only for high efficiency in low rpm water drive

Hi. the boat was designed to be offshore capable and Is I'm my opinion. However a catamaran of this size is on the cusp of what you can get away with for extended cruising and live aboard use. I Think

Thanks for the replies - clear, practical, and encouraging. Bernd, I was previously thinking of putting the tanks under the aft steps, but then I would have to climb out of the cockpit every time to

So after all I will give my sermon to your questions, uncertainties to. I declare the boat as a seagoing/coastal cruiser. Direct to your question weigth. I would build the boat with a weight of 1400

Hi Bernd, I actually also looked in these kind of things, but it seems the flex cable gives too much friction, and is probably not strong enough for a 400 Watt electric motor. I'm not sure why you

Andrew: ??? I think you misconstrued my intentions.........or perhaps I don't communicate very clearly in print.?? When I used the term "circumnavigation", I did not mean it in the sense of

I have a 37foot cat with lifting outboard(s) and have made ocean passages.The tanks do require occasional changing and re-filling at sea that I try to do in calm conditions and try to only motor in

and here the next pictures from Harald. The keel is now covered with Keflar, with some usual problems with this stuff. He used glass fiber strips to tame the material. Was you ever trying to sand a

Separate the aft part of the cockpit benches and store there the petrol tanks. For good ventilation drill big holes in the bridge deck. Bernd

Hi Patrick. Yep theres no problem there. As previously stated, separate system for each motor and tanks in well ventilated area are the go. On my single outboard set up, I use 2 x 45l tanks plumbed
