Hi My masts are pretty limber, so compression -> slack luff -> baggy sail shape is a problem in any sort of wind, if I cleat the halyard at the mast base. I...
Hello , I do not think the reduction in compression load would matter as the compression from halyard would be negligible compared to the bending loads on...
G'day, Wing mast is included in the plans, or wil be when I have done the building instructions. Pretty easy to build if you can use a vacuum pump, which in...
Hey Rob, I'm from Ocean Shores, just north of Byron Bay so a delivery price would be good. As for the mast, what would you recomend? Is it possible to build a...
-I think one of the points is that it reduces compression loads on the mast to have the catch at the top. Also, there are some pretty low stretch rope nowadays...
G'day, No problem using foam, nor using the Farrier method, except it is very time consuming to prepare (you virtually strip plank half a hull), to build (lots...
Sorry if I jump in, and I have been following this thread only as much as possible. But, all boats I've sailed on, big and small, use wire for halyards. There...
Gardner, In response to you questions. 4KW is the expected consumption of 8-10KW electric lumbering at less than hull speed for 2.5 hours. Might be worse than...
Hi, I think you have summed up random findings of mine very well. I have a couple questions. You mention that your monohull would require a 4KW electric, but...
In my quest for ideal auxiliary propulsion for our beloved cruising proas, I have hit a snag. The proverbial weight spiral has begun. Today's technology has...

http://www.nida-core.com/english/nidaprod_honeyinfo_working.htm Polyprop melts at 160, scrim at 240, hot stamping is done at 200. probably 40 degree useful...
Hi Rob, Thanks for the prompt reply, so the general idea flying round in my head is for a foam version of the camping elementarry, Is it possible to build...
Thanks for you frank reporting of mistakes/problems as well as milestones, Rob. Your openness is a blessing to those of us who are trying to learn... This is...
G'day, Can't find it on the Nida web page, but the honeycomb cells are a bit lower melting point than the felt scrim. Problem with too much heat, if you over...
Here are two clips of a shunt with square harry flat bottom hulls. Windward hull with a little rock and leeward with non. The winds are from 8 to 12 mph and...
G'day, There are a few variables to sort out but the basics are as follows: ww hull and decks and bulkheads area 6 sq m/65 sq' lw hull and decks and bulkheads...
Hi everyone, Ive been interested in the camping version of the elementarry for quite some time and Im wondering if anyone has a basic knowledge of how much...
I'd like to add some small points. The Harry ww hulls are not really that heavy. Traditional canoes hulls would be a fair bit heavier, so it would be difficult...
... To make a hot press, get some steel box section insulated on three sides-rockwool or glass wool batts semi permanently and one the other side with a...
G'day, Gardner, it was pretty much a case of everyone knowing, no one trying it. As kevin says, harrys are not magic. Also, 10 years of playing with them has...
G'day, ... Would need to be quite a bit of extra glass (basalt, actually) as it is only 200 gsm. Bog may have done it, but it introduces another variable. ......
... and this forum, and I ... weight to windward proa ... believed that it would be ... harry's obviously shunt. ... another case of "everyone ... I can't find...
Hi, I was searching for info on proas, other than the harryproa website and this forum, and I came across an old message (from 2003) that mentioned that the...
G'day Rob, -To give you someone else to swear at for stating the obvious with 20/20 hindsight from my armchair. Extra bog or extra glass to avoid the centre V....
G'day, Folded up the ww harriette hull today. Did not go well. Mostly because I rushed it. The centre piece folded beautifully, although it took a bit more ...
