Doug The EC is best done on a very low draft boat, preferably flat hull. The filters will limit your width to 9 ft; the first filter will force you to step...
I also heard that one of the more promising techniques to dealing with sticking in the mud was to wear snowshoes (!) in the water to prevent sinkage... Mike...
Doug, Spend a couple of hours at this site. http://www.watertribe.com/Default.aspx?ucPtr=WaterTribeHome.ascx Filter is a term used to describe an obstacle...
In this context a physical constraint of the course which prevents boats with cetain characteristics from getting through. A filter for removing solids of a...
Hi Rob, I am not sure if I should post questions to you on my design via private email, or the forum. Since there aren't any specific structure or finance...
G'day, here is fine. Answers follow questions ... A bit more to it than max and min (boat weight, cabin and cockpit set up, beam location), but basically...
Rob, I have read somewhere that cats and tris aim for a minimum of 8:1 to prevent stern squatting in the manner of a mono-hull. For the ww hull an 8:1 would...
When doing calculations of surface area, I found that with the displacement of Harrys, from about 12:1 to about 16:1 for the ww hulll there was not a great...
G'day, The weight transfer does not happen until the breeze is pretty strong, and the speed exceeds the hull speed of a short, fat hull very quickly. eg, the...
since my design turned out to be practically identical to harry in length, width and weight, I would like to check against that design. Can you tell me what...
Hi hi, Â the other day on a pleasant reach in moderte 10-12 knots (maybe more) I dumped off the aft sheet and noticed the boat fall down on it's ww hull....
G'day, Aroha has 600mm/2' beam clearance, beams are 200 high x 300 wide (8" x 12") waterline beams are 750 and 500mm (30" and 20"). I have not sailed on Aroha,...
hi robert, Â i have gone up through the top of a big wave and come down with a little bit of a slap, but really nothing much. lw hull that is. ww never gets...
Why cut the mast in half? Why not cut it 39 feet from the top? This will put the join closer to the bottom of the mast where not so much bend is needed deepee ...
That's interesting. I was thinking it would make more sense to cut it 39 feet from the bottom, so the join will be in an area of low stress. Perhaps halfway...
Rob, I would like to compare to a known quantity. I know you have sailed Harrigami, and said that it sails at wind speed up to about 15 kts, so could you give...
G'day, No news. No confirmation they have actually left for NZ, either. I spoke to NZ customs who know nothing. Will try Aus customs and see if they have...
G'day, No idea, sorry. Lee hull was 600 wide (I had to be able to get inside) and had semi circular sections, but I can't remember where it floated. ww hull...
Hi, That helps alot. I am looking at 500mm lw and 600mm ww, with semicircular bottoms and vertical sides, so I can tell from your numbers that I am not fatter...
hi, Â got the sidecar up on its side (based on lw hull), with the ww hull sitting up in the air. It was quite a lift even using halyard to the mast top (me)...
also used gps for halh an hour: reaches across melville water and back - the port hand marker out in the midlle of the water has the bureaus recording station...
hi again, perhaps it was closer to 9-9:30 am, which bureau (www.bom.gov.au.....wa...perth...daily observations...melville water), gives average 12knots,...
Following on with gardners sidecar cclone, i may look at moving beams outward to ends further, and setting up a stepped bunk/cooking/seat inside the cabin. ...
G'day, I am pleased to announce that James Brett http://www.jbyachtdesigns.co.nz/ has joined forces with me to bounce ideas off and to take over the drafting...
Hi Rob that is excellent news - both - you building a Solitarry and the addition of a new member to your team. I am confident that the building process of the...
