Well I was getting down to two weeks before the brown stain returned after the Oxalic acid treatment, and following with a wax.
If you look at the bows of many boats in a bay there are many with brown stains. Somedays I'm not sure marine paint has improved over time...
-
I've used many of the products above, but have had the stain return relatively quickly, despite trying various waxes. Note this is on two part polyurethane paint, not gel coat.
Six months ago clear coated my boat with Nyalic by roller, and to their spec. The brown stain stayed away! I'm most impressed by the product. Not cheap, but effective.
(The usual disclaimer here of having nothing to do with the company mentioned, just recommending a good product)

Come on Knot Me, expand on this!
Convince me that Spectra/Dyneema doesn't creep like it used to. I've been way happier with my Vectran halyard than the last Spectra one. The latter seemed to grow 150mm in a Coastal classic.
So what's changed?
A good thread here
It'll be Vectran, not spectra.
The chafe sleeve will be dyneema.
Bit surprised to hear vectran is still being recommended for halyards considering the options available.
DO NOT...... DO NOT let UV get anywhere near the Vectran. The US military and ISIS are far better mates than vectran and UV are.

Cat 3

Hey I resemble that comment, except that I'm not swanning, but working hard, and had one foil borne sail on the AC 45 last week, which was epic!
I'm sure someone at YNZ can direct you to a keen inspector.
While you have the topic up, this is a Rule change year, so if there is discussion on possible safety rule changes you would like to see, feel free to suggest or debate them.
Getting rid of flares looks like the current hot topic, and is being well covered.
So are there other items?

I think you may be heading down the wrong path with an electric outboard. It essentially is there to power a dinghy, and so has engine and prop size, as well as overall strength of the unit, to match that purpose and load.
Have you looked at something like this: http://www.thunderstruck-ev.com/
( no I have no business relationship with them) But I have used their systems in two of my electric boats. If you have a through hull shaft you are nearly there in terms of installation, strength etc. And as soon as you are sailing you can generate from this motor.
But also I agree with much of what's been said here. The battery technology is simply not there to provide adequate motoring time as yet. I think motoring back from the Barrier on a calm day is what would be expected, and only just possible if done well/right.

Is this modern composite Multihulls or ancient history we are discussing?? Do you mean the boat is 13m x 8.5m? Oh I see the weight is in modern units!
well that's the old boat a 1988 john shuttleworth advantage 43 x 28 ft. Foam sandwich single daggerboard and claimed weight of 4000 kg empty and 7000 loaded. b

I thought an iPad would be an adequate answer for my navigation with Navionics loaded. What I didn't see as a problem that on a bright sunny day, the USB based charger can't keep up with the screen brightness energy demand, and so gradually goes flat. For cruising it would be perhaps ok to have to swipe it occasionally to activate the screen on an auto off screen mode, but for racing it is nice to repeatedly glance at the information, sailing angles, speed etc on screen. So not the answer I was looking for. Mid term I'll be looking for a marine GPS chart plotter again...

40 Years ago this country changed to metric. Your boats were most likely dimensioned at build in metric. Your depth sounder has metres on it. The charts are in metric. Time to change I'd suggest!

We do it at Sandspit with adequate results, over both windward leewards and longer, around the island racing. I can't give the task away! A good system simply rewards the most improved boat in a season or series. If you are consistent, relative to the fleet average, you come mid fleet.
No point in taking club mixed racing too seriously.
I use a system which increases the winners handicap, and reduces the last boat, and proportionally changes the boats in between. Tim B developed it for the Multihull Yacht club years ago.
Like for any handicap system a windy, fast race favours the fast boats, and a drifter favours the slow boats.
But it takes years to let the system average out performance handicaps...
-
Plus a head board slug or car that is not going to break or pull out of the sail track, reef points that are seriously strong enough, mainsheet winch that has got enough purchase etc etc...
Watch your mainsheet system. Roachy sails like to have oodles of leach tension to standup the top of the sail properly, which can lead into a spiral of more mainsheet purchase, stronger boom, bigger traveller, stronger back beam to cope with it all.
Not saying its a bad thing, just something to be aware of.
-
The sail looks surprisingly draft forward for a mulithull mainsail. To my eye it looks more like a jib in terms of draft position.
But still a good buy at that price.

I've got a similar problem with rolling lines on my projector image when powered up from 12V. The problem disappears when the projector is powered up by onboard 240 AC power. I've tried twisting feed wires, ferrite cores on everything etc too no avail. Recently had a interference expert aboard, but he couldn't figure it either.
But I still blame the solar controller.
First World un solvable problem I guess...

And then the next day they went back to Whitianga in very challenging Easterly conditions. I wonder if they made it...
We watched about a 9m bridge cat swingng about on its anchor in the cove at GMI New Years Eve. The skipper of the neighbouring cat was concerned it was going to drag and hit him, so came across to Pulse to get some help to sort the problem.
Mr DT (previously Two2Tango) accompanied him to the offending vessel, where they weighed the small plough anchor on the end of just over 1m of chain, and attempted to re-anchor. The thing wouldn't steer into the wind (over 30kts), so they ended up tying her up to one of the house boats.
Thing is, they had left their boat unattended, rudders down (they were not able to be raised) helm not tied back, in winds forcast to be knarly, on 1.8m of chain and an undersized anchor.
Really have to wonder about the intelligence of some people sometimes.
I know we all make mistakes, and when I first joined here, I did so in order to learn what I did not know. And when in doubt, one asks questions to ensure they keep themselves and others safe.
TBH, I was gobsmacked.

Yes Fat Freddies Drop. Going to be Fun!

I'll be there Friday and Saturday, but off to Waiheke on Sunday for a concert.
If there is real interest on a race on Sunday I could organise a race start at 1105. This could be to Bon Accord (or Waiheke for a change?) Let me know.
Is there a Multihull race up Friday night? I'm happy to do a finish line if need be
Will the Open 8.5 fleet look at their shoes while not doing either the BOI race week or Mahurangi weekend?
Are a few beers, a sleeping bag and a few meals so heavy it prevents sailing and having fun?

Pulse xtc in the PIC Coastal Classic 2015.
We got a good right hand side start, but conservatively didn’t put an extra on, thinking it was going to be a long uphill race, and we didn’t want the sail on the tramp. After North head we were quickly on a powered up two sail reach, Pulse feeling powered up and fast. Ben on the mainsheet, Kushila trimming the jib, and me picking the line between boats. By Tiri passage we felt like we were amongst good company, with lots of big black sails around us.
Kawau Island went past in two and a half hours; a much better time than we expected with the breeze being slightly more Westerly than forecast.
But by Omaha Bay the breeze swung around on the nose, and felt shifty and unstable. We tacked in on every shift to stay lift close to the shore. We had three Open 8.5s around us, and Pulse was going well upwind in the light against them, much to every ones surprise!
Just off Whangarei the breeze went Westerly again, and we were reaching straight into the Northerly chop, crashing through the waves. Eventually we got the screacher up, but no sooner than that happened and it had to come down again.
It was great to have some nice hot food, and coffees and soups through the night. Have to feel sorry for the boats not taking cookers!
Nighttime was like a semi blind folded game of chess. Really a beautiful night, with the moon glowing through the Mylar sails, and dolphins occasionally playing in the bow waves.
Mostly our tactics went well, but one tack into shore at the wrong time, straight into a hole in the breeze, and it looked like the whole local fleet sailed past.
By dawn the wind had increased, and we were down to staysail and one reef, crashing into the choppy seas. As the light increased, I realised all was not well with our mainsail; the head was not attached to the car. So off Whangamumu down came the mainsail. We realised it was just the webbing, so a quick re lashing and we were back sailing. But not long after it happened again. On dropping the main we could see the alloy top car had broken. Sail slug had to be dropped out of the mast track, the head car exchanged, lashed again to the head ring and re hoisted. A fair loss of sense of humour by the skipper by this time.
We headed out to sea on port with the rain setting in and the North Island disappearing in the murk, while expecting the strong Northerly change. Not wanting to sheet the main on for fear of damage, we took it gently, but the wind built for us to perhaps 35 knots. So we changed right down to three reefs and storm jib. Tacking back in we still weren’t laying the Brett, and the wind started easing. So the jibs were changed again, and two of the main sail reefs shaken out.
Past Piercy Island at 1200, which meant two hours to the finish cut off. Sheeted on the tight reach we were only doing five knots, and needed to be doing eight. So I figured the safest place for the damaged head car was at the top of the mast, supported by the halyard. So up went the mainsail to the top of the mast. Past Whale rock and the wind freed and increased. We all were concentrating hard to trim and get the best speed from the boat, as we counted down the time on distance, which was very marginal. But a fast reach saw us close the finish with all of eight minuted to spare. It was great to hear the cheering from the finish boat, and horns sounding ashore!
After 28 hours of racing, it was great to get out of the wet gear, have a quick drink, and go to bed for a couple of hours!
Thanks again to my great crew of Kushila and Ben, a splendid effort to get us across the finish line.
Thanks also to the organisers at NZMYC for putting together a very well organised race. Watching the tracker later was fascinating. Thanks too to PIC insurance, and Musto for the great prizes!
I wouldn’t have said so on Sunday, but roll on next years race!

I don't know the owner but got these shots of Spank on the return trip. Please pass them on if you know them!
I'll write up the Pulse story soon...

I'd have to agree. It does seem amazing how long relatively light laminate sails are lasting.
The failure mode seems to be in the details, such as around reef patches. This is where the original sail maker shows his worth, as the sail nears the end of its life.
The other failure I've seen on mine is rounding the top mark with lots of luff and mainsheet tension on the main, and easing out the sheet. Suddenly all that mainsheet load ends up on the luff tension, and is very hard on the forward top seems and fabric.
Because of the above I'm not sure about using lots of luff tension to move the draft forward on a composite sail. I'm of the 'just take the wrinkles out' school of thought.
Sure on dacron Tornado and PT mainsails we used lots and lots of luff tension to bend the mast, open the leach and move the draft forward. But I'm not convinced it it effective on bigger boats with radial sails.
Awaiting other opinions on this...
-
I encourage all the large cruising multihulls that get Cat 1 to join the NZMYC, (Ok not all of them do, but most do) so there should be a data base of cruising as well as active racing boats.
Sounds like this all has some momentum happening, especially when you look at how many have viewed this topic! Keep the ideas coming, and tell us all if you are interested in joining in.
If we pen in Anniversary weekend at Mahurangi and Kawau, then someone with the race calendar needs to pick a weekend for the Motuihe event. Then there is Easter. Have we just got a three weekend cruising series going??
-
Yes some great ideas there.
Earlier last season I proposed a fairly similar idea but at Kawau. I had also sorts of things in place, but in the end little real support for the regatta.
One of our problems is how the boats have evolved, and how their owners prefer to use them. The racing boats are now just for that, with little accommodation, or desire to stay aboard. There are few 'cruiser racers' around, and many dedicated cruising boats.
Also of course there is a very full program in Auckland of racing and events.
The Anniversary weekend at Mahurangi and Kawau has been very successful in the past, and I still feel it's the easiest one to build on. Friday evening race to Mahurangi, with lots of other clubs doing the same thing. Lots of family events with the Classic Yachts and Mahurangi Cruising Club ashore on the Saturday. I could organise a race start on the Sunday to Kawau if there was interest. Sandspit is already doing a race and we could possible tag along. The new Kawau Yacht Club is going well, and deserves to be supported. Finally, there could be a race back to Auckland. This whole event could involve both racing and cruising boats. Possibly some of the 8.5s could buddy up with a larger cat.
Who's keen?
A couple of random ideas...
(1) In my PT days there was a regatta held in Bream Bay every year.
It was a two day event titled something like "Upper North Island Paper Tiger Challenge" and the idea was that Northland boats could race without the journey down country, and the Auckland boats got to travel north. It was open to all small cats, and run, IIRC, jointly by the NZPTOA and Marsden YC.
Not certain, but I think even TC may have attended a few of these.
Maybe something similar could be organised for bigger boats? Plan it for a 3day weekend, and visitors could take friday off to sail there (from Aucks or BOI) and sail home again on Monday.
I'm sure Whangarei Cruising Club could put on some entertainment at Parua Bay. Maybe they could even organise some parking in case the weather doesn't play ball.
This could provide the chance for all the north-based boats to sail on slightly more local waters.
and (2)... Shamelessly borrowed idea from Thornbury SC in SW England. Family week.
A fun race week, with a whole heap of crazy fun events. BBQ for breakfast each day, teams organised to each cook a communal dinner each night. BYO Lunches 'cos we'd be out racing/cruising/whatever.
Fun races, perhaps one where you have to take the dinghy ashore to pick up a tag a few times at strategic points, kind of like orienteering, but in boats.
Perhaps a wheel race, where six or seven points are chosen as rounding marks, and all must be rounded the same way (port/stbd) but in any order, except that you must round the centre "hub" after each mark.
Prizes awarded for race winners (HCP) as well as best oopsie, worst dressed, youngest person seen on the helm, or anything else the OD sees fit.
At TSC we also had a marquee, with karaoke etc on in the evenings, not sure whether that bit could be done.

Meanwhile scrubbing and antifouling on piles, or the beach, is discouraged or banned, so making antifouling a complex and expensive task.
So on one hand clean hulls are wanted, on the other there is a higher degree of difficulty in getting it done...
-
Okay let's aim for the afternoon of Sunday the 4th October.
If I haven't checked you or e-mailed you please come back to me via e-mail
Thanks
-
Copy that about Oct 3rd. I'll plan for another day. The next weekend looks booked up for me for sailing.
I'm coming through Auckland Friday morning if anyone is quietly working on their boat then...
It may have to be the 17th October otherwise. What's the sailing schedule then like folks?
-
Hi All,
Coastal Classic looms again for us all.
If you are wanting to do a YNZ Category 3 inspection on your boat prior to Labour weekend please let me know.
I'm looking at booking them up for Saturday Oct 3rd.
Please e-mail me with your name, boat name and contact details to:
, with Cat 3 in the subject line. Please don't PM me here, or Facebook message or text to start with. I would like them all on the same system please.
If you've booked with me a while ago no harm in reminding me again.
Please ensure everything is ready, and you've either checked properly your inflatable lifejackets, or had them checked as per manufacturers instructions.
You are of course welcome to use any inspector for this. But note I do represent you all at rules change meetings, and do my best to keep multihull safety sensible.
deck paint
in TechTalk
Posted
I'd agree with VB on this. The grey is too dark/hot, but the 1:1 mix reduces deck clear enough, and is much cooler. I've had this product on Pulse for 14 years. It has worked fine on the curved side deck, but not so well on the cockpit floor that tends to stay damp. It peels off after a year or two. Possibly there is a good undercoat out there that would help in the areas...
