G'day, You have come to the right place. A Visionarry would do would you want, with ease, and a lot lighter than 7 tonnes. Plywood/foam/plywood is a good way...
... Make them both steerable :) Seems like it might be worth trying some experiments on a smaller harry-type boat first to see what works and what doesn't. ...
Hi Dave, Rob called the inventor at the SPW site. They are a long way off from a commerical product. Farther than the Multihulls article suggested. The...
Good day hi long ago with egroups I've been in some proa groups so still looking is there a chance for 4 and 2 kids with modern comfort eg watermaker, fridge...
... For myself, I'd rather have the wind blowing onto the dock, but that's with a much smaller F-27. As long as the fenders are out and the boat is close to...
Thanks greatly for all your suggestions. Which so yo think is the bigger problem blowing into or away from the dock ? My mono blowing away is usually no issue....
It seems to me that docking a proa has some things in common with other multihulls and some things different. In common is the fact that because of the light...
I think you guys are missing a great opportunity here. Go with a electric drive that is mounted on beam or from hull that can rotate 360 degrees and can also ...
JT, -Have been thinking a bit more on the subject. The long thin foils on the rudders are probably not so suitable for redirecting prop thrust but might be OK...
Hi ya Tony ! I can see the wisdom in the OB's but they do have their limitations. They are much quieter than they used to be, but still there are those who...
Robert, Thanks for the input. I am optimistic about the fore aft rudder opportunity, but only testing will yet determine response. That 50-70 ft LW hull is...
I tend to agree that the outboard option will get you on the water earlier. It has the added advantage of being fully removable for service etc. As a financial...
Good to hear from you. I've had a little bit of experience with bow thrusters on fishing boats. They are bow thrusters and really need to be at the bows to...
Been so long nearly forgot my password ! With the progress so far with Johnnie's boat, the visionarry in latest stage of development, the aux drive has left me...
G'day, My masts are 47' long with only 3' of bury. Shows what can be done. The diameter at the base is 10".At the mast head the diameter is about 6"{not going...
My masts are 47' long with only 3' of bury. The diameter at the base is 10".At the mast head the diameter is about 6"{not going up the mast to find out ...
Just a thought but have you considered zipper reefing? They use it on skiffs if you can't afford a whole suite of sails. You simply unzip the lower panels off...
G'day, Sorry for the delay, having Yahoo problems. With round masts, the skin thickness required is such that no core is necessary. Therefore the core is just...
On a double sided sail with a wishbone like mine the out hall must be released to allow the wishbone to go up and down with the sail. The peak on a gaff must...
Maybe it is possible to have battens equipped with jaws like booms and gaffs have on classic boats. Like Bolger's 'chinese gaff' rig, but with the addition of...
I was thinking that a type of flow media could be placed between the layers of carbon fiber I have read of a structural core made specifically for this ...
G'day, Infusion may work on the smaller masts, but I suspect it would be [problematic on laminates more than 3mm thick, unless the off axis material also...
I was wondering if resin infusion might be useful for fabricating the carbon strips. Is there any news of the new method for production mast building? When...
G'day, Rob is busy, but not as busy as Mark, who has a nearly finished Elementarry, Harry and Visionarry in the shed, as well as an order for the next...
Me thinks Rob is too busy. Still waiting on funding status for my wingsail for the elementary. Rob intends to finger point the fab, so mostly I am out of the...
Is everyone too busy sailing/building/working to catch the Harry group up on life, the universe, and everything? Peace, Mitch watching the frost on the ports...
G'day, Glad you like the boat. I was pretty impressed myself. Harry ww hull bare: 350kg, lw hull bare without bows, bulkheads and sockets: 135kg. Finished...
