    It means, when there are people here asking very simple questions about these boats, it's not helpful to bombard them with minutiae. Also between us, this is again becoming a rubbernecking thread. I'll stop posting if it prevents that.

    ProaSailor's comments are a good example of why it's important to hear from actual proa sailors. Harry, Atlantic or otherwise. It's time to put arguments based in theory on the shelf and hear some actual sailing experiences. According to Rob, there are many HarryProa designs actively sailing. Do any of those owners read this forum?

    As usual we are in vehement agreement.

    I'm pretty sure that 50% displacement in the windward hull is due to having the accomodations in the ama, but I know you enjoy putting me in my place

    It's basically a pacific proa with the accomodations in the "ama". That's the biggest difference.

    Just to clarify, Rob's designs aren't Atlantic proas. Google "proa Cheers"

    I don't think it's that clear cut. Wess asked me some honest questions here and I gave him honest answers. I don't think there was an agenda, but clearly there are some people who just don't understand how these boats work as a sailing platform, and they have questions. But I think it's on the sailors, not the designers to answer those questions. I mean, how much time does Rod Johnstone spend fielding questions in JBoat Anarchy?

    I think it would be more insightful to hear from HarryProa sailors than from Rob, about sailing his designs, considering he doesn't have any extensive voyaging experience on his own designs. After all they are the ones sailing his boats the most and will have more to share about their characteristics. I feel like Sidecar and I have been pretty open and public with our sailing experiences. It would be great to hear from some HarryProa owners, who I would consider a more reliable authority on Rob's designs. As you have noticed, there are a lot of questions about proas and it's important to answer them based on experience rather than theory.

    Yes, and much lighter and low volume all around. It would be a fantastic boat for camping and cruising around the Chesapeake, which is essentially what it's going to be doing.

    Damaged during transport or something. I can't remember the exact story, but it wasn't sailing related.

    I was on Madness a couple of times last week and didn't notice anything unusual about the foil setup. Besides a new mast, I don't think the boat has had much done to it since launching.

    Never forget the brave men and women who used to race ORMA 60's across the Atlantic solo. For sure they were not flying two hulls whenever possible, but they certainly did on occasion.

    That's probably not true, but I know what you meant.

    It's pretty awesome racing with a crew though, where there is someone constantly flying the ama with the mainsheet. Unfortunately it's not possible singlehanded for any extended period.

    Honestly I've never had solid water come above the prow and never felt the bow stuff in the back of a wave the way I have with other boats, especially monohulls. The mast on Jzerro is only 36' off the deck and the main hull is 36' long, so it has much less leverage up high driving the bow down than a similarly sized trimaran, cat or monohull. Also, the main hull of Jzerro has quite a lot of reserve buoyancy and freeboard. It's nothing like pushing a trimaran hard down wind. I have not sailed her in sustained winds above 40 knots, but have been happy with her stability in the 30's. I distribute balance between sail area and water ballast. In a big sea state, jzerro seems happiest with reduced sail area rather than loading the ama with a lot of ballast. The ride is easier. As for the pod, besides the damage I recently experience, it's been extremely useful and I would never singlehand a proa offshore without something to leeward. It definitely prevents the ama from flying too high and gives me plenty of time to react with sail trim or by slowing the boat down, reducing apparent wind and in turn, returning the ama to the water. Typically one or two of those and I reduce sail, add ballast or both. Downwind the pod is essentially along for the ride and I've never had a roundup or round down.

    I'm only referring to pacific proas. When trying to understand the beam loads, consider where the mast is mounted and where the sail forces are directed. I have never sailed a trimaran offshore solo. I have with a crew and have spent hours watching beams flexing and leeward hulls going under water at speed. Jzerro certainly feels safer than the trimarans I've taken offshore, but I'd never claim with authority that it is. One thing I'm certain of is that singlehanding multhulls offshore at speed is a lot more stressful and dangerous than singlehanding monohulls. I think Peyron said it, but essentially it's fewer sail changes with more stress. Can we get to the important question here though? How many people here have flown a gyrocopter?

    Compared to a trimaran or catamaran which relay more on buoyancy to leeward than weight to windward for righting moment, therefor placing more load on their leeward beams while sailing than a pacific proa does on it's permanently windward beams.

    What shit slinging? Please explain?

    I'm enjoying the electric motor chat. Especially if it ends in an easy hydrogenerator hack.

    I think the big difference is that, were Jzerro to have a stern, there would be more deck space for solar. However, in practice both ends are bows and I have to be able to safely do sail handling on either end, so I'm choosing non-skid over solar for that reason. The catchment system is really a back up. I don't plan to rely on it for water as the sole provider. I've used watermakers extensively and have never had them fail during a long trip, but having a simple backup system is probably a good idea.

    The 300/day minimum was something I only set for the first three days. Sorry I didn't make that more clear. It's just to get an early push for the record and likely the only time conditions would allow that for three consecutive days. As we discussed, the payload can be reduced dramatically and in a way that will make this record a lot safer. This isn't an insurmountable problem, but of course it's risky voyage. There will always be a group of people on standby to say "I told you so", and to avoid becoming one of them myself I often think of Mike Birch's 1976 podium OSTAR finish on the Val 31'Third Turtle. It always lifts my spirits.

    That link is pretty wild. We'll be rebuilding Jzerro at Jim Brown's property and I'll definitely work with him on some clever rain water catching options.

    I think we all get that. Thanks.

    Interesting for sure. I discussed something similar with the WindGen guy. I can't put more solar on the deck. I have a different sail plan and use it for sail changes, so I need the nonskid area. A good hydro solution would more than make up for the lack of solar, especially if I am also using the EFOY.

    Yes, but it has to be well clear of the water, so it's another 3 meter pole on the ama. Jzerro's a bit small for that. I'm not writing it off totally, but it's less attractive when mounting it is really considered.
