Another small benefit is that lying down reduces windage. Might be significant if you are using a small sail.
To illustrate my point above, I've attached the image I referred to and marked on it in red the axis of symmetry of the heeled waterline and in...
I think you will find that this boat has a gybing keel. You can just make out the rotated orientation of the keel on the plan view image on the...
This discussion seems to suggest that the longer you make the spreaders, the more prebend you will get but the less forestay tension you will...
The grab rails are bolted to the cockpit sides and are made of a plastic which I have seen fail due possibly to UV degredation. I'd be more...
No. The bow analogy is right. Most of the extra tension was going into compressing the mast to create the pre bend. But with a deck stepped...
The latest rules (2008) are at http://www.intcanoe.org/library/APPENDIX%20IV%20Jan%202008.pdf The new rules prohibit more than one centreboard...
Here in Australia we have an 8' pram bow dinghy called a "Manly Junior" (MJ) which will plane quite nicely with two young kids on board. The sail...
I don't use Solidworks, but I use Inventor, which is similar. To get the general dimensions, I would drag some images off the net from PDF...
While it's a good idea to be made aware of our chances of success, I'm not sure it's such a good idea to dissuade people from having a go at...
When I tested a 1:5 model of a 6m sailing multihull, I did indeed scale the foils up (relatively) for the reasons you mention. From memory I...
What I usually do these days is to choose a mathematically derived low wave drag (theoretically) volume distribution (curve of areas) first, such...
I haven't used Hullform. Out of curiosity, does it calculate the CP for each end from midships, or from the maximum cross sectional area position....
I'm well on track to make my Spring 2050 launch date. For all the reasons that Cut Once mentions, this is not a high priority project. The design...
Vlad, It would be a bit dissapointing for many if I had convinced you. I look forward to seeing SpeedDreem on the water. Cheers, Mal.
Vlad, Thanks for your response. Both SD and a multihull can capsize to leeward with equal veracity. A multihull however will not capsize to...
Vlad, I don't have a feud with Doug, although I have had some robust discussions with him in the past. His enthusiasm for his chosen interests...
Hey Vlad, I wasn't really having a go at the designer. I was really just winding up our mate Doug (a pointless exercise I know). As we all...
It's a proa, but with added features to make it slower, uglier and more difficult to sail.
Assuming you use a constant section shape for the full length (span) of the centerboard, the theory is that minimum induced drag is achieved by...
