A bit of fun and a chance to win $500 on the Race Forum http://crew.org.nz/forum/index.php/topic/13087-win-a-day-on-bucket-list-or-500/

I have posted this here rather than on the Multihulls page as a) the speeds required are just guesses and Bucket List is designed so that anyone who knows how to sail can race it. After any teething troubles are sorted out, Bucket List will be sailed upwind and reaching. The gps recordings will be shown on http://harryproa.com/?page_id=1620 Upwind: It will be sailed upwind for 5 minutes, shunted, then upwind on the other board for 5 minutes. What will be the distance between the start and finish points? Answer in nautical miles to two decimal places. eg, if it sails at 10 knot

Best part of 5 years since I spoke about easy boat building at the club. Thought some of you might appreciate an update. The method has evolved to the stage where we can build without any cutting, grinding or sanding of cured laminate, no fairing or mould polishing and no hand laminating. The first complete boat to be built this way is the T60, a 7.5m long tender for the C60, which is currently being built by Ballotta in Peru. 90% of the C60 is built the same way, the rest using conventional methods. The time and cost savings are significant, the dust and mess reduction large. The

There are two methods. Presume you are talking about the one in the video. It is not like tortured ply as the panels are only bent in one direction. The sides are parallel for the middle 4 m of the 6m hull, and the ends squeezed together. The bulge at the bottom that this causes is either manipulated or cut off and replaced with polystyrene and glassed over. This is my preferred method as it acts as a very good collision bumper and inbuilt buoyancy. Where there is a sharp bend (gunwhales, seats, hull bottom, the foam is replaced with uni glass so that it bends to the correct radius. On

A beam with the "carbon look", 5.5 metres long, trampoline tracks, stainless inserts and compression tubes (the works), for a boat with righting moment of 7000 kg.metres is a paltry $Aus9500. $8,000 if you can live with it being painted. The "easy build method" statement has been made a lot of times, including by me about the system in the video. Do you know of a quicker way of building 95% of a hull, deck, bunks and cockpit than folding it up out of 3 sheets of material that took a week to lay up and laminate on a flat table? A bit more detail about the the moulded hulls stateme

Build is on the Gold Coast. Builder is an excellent infuser, but has peculiar ideas about time. Owner is a German, but I get the boat for extended sea trials before it is shipped. State of play is that the lee hull is now closed up, the foam glass ends and paint to go. The guy is Derek Kelsall, the method KSS. One of the multihull pioneers and the most experienced and innovative foam boat builder in the world. 80 something year old pom, still going strong, currently living in Waihi. I copied what he has done with infused panels, and simplified it for harryproas which have much

A video my daughter put together using the construction photos of the professionally built 15m/50'ter that was started shortly after my talk and is discussed in this thread. Way behind schedule for various non boat reasons over which I have no control, but slowly coming together. http://www.youtube.com/watch?v=j5idbIo1 ... e=youtu.be rob

ScottieE, So it does. Silly me. Not much help for the CC, or for getting out of NZ in a cruising proa. I'm happy to go round in circles on these points if you, The Rev or anyone else can add anything to the conversation. Samin, I got over W in the CC the same day Jason banned it, 12 years ago. You bought it up last week when you thought you could score some more cheap points. 18 months ago, you gave me a hard time about my version of the banning, said you would ask Jason whether my version of events was correct or not. You have piked out of answering ever since. As you know, m

Reply to some questions from the closed Rob vs Tim thread. I have lost the originals, so anything that is not clear, please say so. markm, Pretty much correct. That was the state of play when the ISAF introduced the ban. There were Atlantic proas (80-90% of weight in the ww hull) and Pacific proas (80-90% of weight in the leeward hull). Both pretty dangerous for shorthanded offshore racing, but sailed quickly until they fell over or broke. I combined the two and made a harryproa, which has the rig and rudders in the lee hull and the crew, accommodation and all the gear in the ww hull

Oops, missed this. Gold Coast. rob

Hulls and beam are indeed sorted, although I am having second thoughts about the single beam idea. The rig was on hold until the 16m table was built as I wanted to build a mast from a flat panel. The infusers are raving perfectionists so the table has taken a while, but it is now complete. In the meantime, and based partly on my hulls, we have got a lot of work (see above) which has taken priority. Tough for my sailing aspirations, but I can live with it as the deal for the new proa is a good one. The new build will be photographed and detailed as it happens. For the record, the cost

Ye of little faith. Tim will apologise for misleading everyone, blame it on disappointment about the overweight and do what he should have done in the first place. Detail the 75 kg calculations (maybe the hours as well), then explain where he went wrong. With a bit of luck, he will learn a bit of humility and not be so quick to attack others in future. And Gary will apologise for being unprofessional, give his take on why the weight was so high and we can all discuss how it could have been done better/made lighter, which is what the forum is all about. Rob

Perhaps you should have. 75kgs vs 125kgs, with more to come is pretty embarrassing for professional builders. (sorry gary, unfortunately not joking) I disagreed with you when you wrote this, but it looks like you were partially correct. However, you have a really low opinion of your fellow sailors if you think they are gullible enough to believe that one of the most experienced composite boat builders and multihull sailors in NZ, with the help of one of the most careful designers, really put all that time and effort into designing the hulls for his pride and joy but "never rea

You are sounding strident/desperate again, Tim. You asked if any of my ideas were in your hull. I reluctantly responded, and quoted some of your previous posts. As usual, you ignore the boating aspects and try to make it personal. Don't be so hard on yourself. You obviously know what you are doing, but are doing it the same way you did in 1989, although apparently not the bits that add quality and save weight, like vac bagging the exterior. Don't be daft. I just don't have the patience, time or money to build boats your way any more (haven't since an 11m race cat in 1982)

I notice that Tim and the other cheap shot artists are still sounding off on the Timberwolf thread. Rather than hijack that thread, I will post a reply here. After making himself look foolish on mast pricing, I expect sour grapes from Tim, but gary? Do you really think it is good business to insult potential clients? Good to see TC is professional enough to stay out of it. Actually, there might be an idea of mine in this hull. When I discussed my current proa build, I said the skin weight was 3.5 kgs per sq m. Tim willetts said it was "impossible", "cuckoo" and

Maybe you should try meeting me. Were you at the meeting? Maybe join one of the forums where people are more interested in discussing boats and ideas rather than launch dates and personalities, you may get a different impression. I said the unstayed rig would not reduce the weight on a racing tri by much. My ideas can and have been be used on cats and tris very successfully. Most extreme example is W (12m cat weighed 600 kgs when launched with freestanding, balanced rig, single rudder, no metal in or on the structure, and sundry other features). Generally speaking, if you want

rob unsupported area is about 1m by 1m you think 100gsm carbon on nomex would be grunty enough? it is the "work bench" after all.... guess it depends on how heavy you are and the point loads. Maybe an issue if there is enough headroom over the bunk for you to kneel on it, but otherwise should be fine. I have only ever used 100 gsm carbon for models as it is expensive. 200 glass works and a very rough rule of thumb is half the carbon for the equivalent strength stiffness. If you can find some nomex panels with 100 carbon, buy them and try them. If they crack or bend, add some stiffen

What is interesting is that it weighs about 3 kgs per sq m (or would if it was infused rather than hand laid) and this is the skin weight that I was given a hard time about last year by Tim C and other experts for a boat which weighs half as much. Can you also let us know the hours, the build time and the cost so far? And when it will be sailing? What is amazing is that last year, you were one of the crowd that said i didn't have a clue about boats or building, 2 weeks ago you were begging me to tell you I wasn't building my boat the way you thought I should, 2 days ago you were t

Clipper, Booboo. Ta. Good to know it was worth the time. Lets hope the outbreak of goodwill lasts longer than it did last time. Sendit, Sorry for the misunderstanding. Look forward to the race if I get over there. Looking forward to seeing you do 5 tacks in half a mile on your own. Happy to waive the Aus leg. I never said I can shunt faster than a fully crewed conventional boat. If I did, please let me know so I can correct it. What I did say is that it may be possible to shunt with better vmg than a tacking boat. Especially shorthanded. Your diagram is correct, for

Think about it and you will see that, like so much of Tim's proa information, it may be amusing, but it doesn't actually happen.

I have never said my boat will beat Taeping. Sendit proposed a race to test speed and maneuverability, I suggested a course and rules that would do this. He declined. Maybe you would like to bring the eggshell out and have a go on the same course, under the same rules? You would then learn about proas without having to read anything. Thank you for your best wishes. If you were to go through all your proa posts and either delete them or apologise for being abusive/ignorant/derogatory your concern would be a bit more believable. If you were to actually read about and make an effort to

I wish you would make up your mind about your enthusiasm for proa racing. Last year they were a joke that no one would want to sail and that would be beaten by a lead mine. Two days ago you were dreaming up rules to ban them. Today, you want it to happen. Tomorrow, who knows? I did not say I got 4 orders from the meeting. I got very little from the meeting apart from a few disbelieving giggles from the back corner. Between 40 and 50 polite people very interested in what I was doing. No abuse, Samin too scared to call me a fuckwit to my face, no one telling me I was cuckoo and that

I have a lot of respect for Murray Jones and the Alinghi design team. I publicly picked them to win the AC. However, the bottom line is that they lost because they did not pursue all their options. Says it all about them not considering proas. I forgot you worked for Murray. Is that why you went along to listen to him instead of coming to the club night? You are wrong about double ended foils with minute aspect ratios such as hulls. Transoms only make sense when you are length limited. Rocker is what makes them draggy. Harryproas have none. See the drag curves on the harry

Maybe I was wrong about stupid. How many times do we have to tell you that a tack and a gybe are not a problem in a harryproa? (not a sally proa, ha ha ha) Not content with finding rules to stop me, you are now inventing them (international juries taking smugness into account). Thanks for the heads up on nav lights. No one had ever mentioned this before, nor your elegant solution. No one that is, except those who have ever thought about proas for more than a nano second. rob

Had a bit of a rethink about your attitude, have you? Do you really think I am going to forget 12 months of your ignorant bullshit and play along with your current Mr Nice Guy image? Eight posts and a rules search, but still no time to come up with a mast price? Doesn't look like time is the problem, must be laziness or fear. 1) You may think it is a 'bit of a laugh' abusing me and trying to destroy my business, I don't. 2) I never said you were stupid, just that you know nothing about harryproas and did not appear to want to learn anything. Nothing you have said since changes t
