I'm glad to see that you are maintaining your sense of humor. I have several fluid dynamics and aerodynamics friends who have doctorates from...
I sailed an RC model of my first wing-powered boat in a pool too. I set up fans at the local Holiday Inn pool, which they let me use for free.
I've got to get busy, but here are a couple ideas: Core can be removed from outside with a hole saw, and if you are very careful, you can leave...
I use hot glue often for this kind of thing. I use as little as possible, and usually as an adjunct to zip ties... I don't generally use wire. I...
I checked your profile and see that you are retired and own a Catalina 22. Therefore you are very well-equipped to test your theory, which...
A few things to be aware of: Many foam core materials do not reach their compressive strength rating until they have been compressed to 90% of...
No, that is the norm. Virtually every monohull (other than dinghy) will recover from a mast-in-the-water knockdown. In order to sail, a trawler...
First, lets assume that this is a displacement boat, and that a more reasonable constant speed target to consider would be 6 knots. We might also...
In general, high thrust requires high power, which requires high rpm. Therefore, if a sail is providing most of the power required for eight knot...
Hi Dan, I did not know, until seeing another post, that the stainless plate with the 4 holes is only 1/8". That means Barry's design is much...
Another thought is to buy or fabricate a larger version of one of these: Heavy Duty Tow Pad Eye - Suncor Stainless...
The wing , if the sheet is not attached, weathervanes, being pivoted on ball bearings (around a CF stub mast) at a point forward of its center of...
Funny... we had exactly the same thoughts at the same time. Alternatively, the the plate could have a bend at the lower edge, instead of a weld. A...
She's a great looking ship! It's hard to judge scale from the pics, but if the netting support tube is 4" spinnaker pole tubing, then those four...
In typical fast modern tris, going fast often entails flying two hulls, so the amas are high prismatic, and substantially greater than "full...
I like your boat! I had a couple pirogues, and made one into a proa with a canted sailing rig. It was great fun. I described it in this thread:...
There are many types of 4# foam, but none can support the pull that a 3/8 stainless bow eye could see. Is this bridle a lifting bridle or a...
That's it. Go build one!
The sail: This was cut hollow on luff and leach, to keep it relatively flat, and had wire in both, I think. I used harken ratchet blocks at the...
The rudder/daggerboards: These were relatively sharp entry (and exit) ogival sections. They were mounted near opposite ends of the pirogue. I...
