    Windrush 14

    Victoria has weird rules allowing standard 6x4 box trailers to not be registered. The rule is specific to length - a 7x4 needs rego - and I believe a trailer designed to carry a boat is also specifically mentioned as requiring rego. So your cat trailer fails on all fronts, and should be registered. There's enough confusion and apathy about trailer rego in Victoria that you can probably get away with it for a while and plead ignorance. I know of quite a few Victorians whose boat trailers have number plates, but which haven't paid rego in years. Looks official enough, and apparently the fine is comparable to the annual rego cost anyway if you do get pulled up on it. I'm in Ballarat and sail a Maricat. Been meaning to bring it down to the Bay for play but never happened yet. Now I've started Laser racing so the cat isn't getting out much at the moment. Silly slow tippy things these monohulls are... but thats what the local racing scene is about so that's the game I'll play.

    Halyard pulleys and sail track lubrication

    Took a look at my sail today and found that this has already been done. The bolt rope is hand-stitched about a foot up the luff, and there's a corresponding extra length of generic rope in the bolt rope sleeve. I've unpicked the hand stitching - will see how things move next time I hoist the sail.

    Cartwheeling (nose diving)

    I actually furled the jib when the wind came up, and intended to race cat-rigged. Milling around before the start... it was awful. Just wouldn't steer. I actually rounded up into the wind and "parked" in irons in the middle of the lake, walked out the bow, untied the reef, unfurled the jib and reconnected the sheet. I didn't need the power, but the boat is so much nicer to sail with the jib up. Especially now I know how to depower the jib and keep the bows above the waterline. I very rarely sail cat-rigged. It's like an entirely different, completely unfamiliar boat. I would quite likely have evolved a different rig setup if I had sailed that way more, and hopefully would have gotten better at tacking without the benefit of a jib to pull me around. The Hobie states are on at our club this weekend. Looking at some of the boats in the yard (I don't get to look at many beach cats close up) - at least one of the H16s has a jib halyard led down the mast so it can be adjusted on the fly. Of course, their jibs are fully battened, which changes the rules completely, but I must read a bit more about how H16 sailors trim their jibs.

    This is true, but once the forestay is tight, it doesn't change length much. The sail itself is much stretchier. I had my sail rigged "short", so the luff stretched quite a bit under static rig tension. Then I tried rigging it longer, so the luff didn't stretch as much under static rig tension. Tensioning the mainsheet will, of course, add tension to the forestay, but the wire doesn't elongate to any significant extent, so the jib luff doesn't elongate either. Almost the opposite of mainsail luff tension, I found that a tighter jib luff causes the sail to bag up, and get lots of draft. Looser luff made the jib flatter, which was easier to handle in heavy air.

    Halyard pulleys and sail track lubrication

    Halyard pulleys sorted. As a stop gap at least. I was in Geelong this afternoon where my "local" chandlery is. Turns out they go sailing Sunday afternoon and shut the shop. Good for them, but I have no plans to get anywhere near a chandlery again, any time soon 😕 Bunnings to the rescue. Sliding door wheels are a lot like mast head sheaves. They all have ball bearings rather than being plain nylon, but there's a heavy duty option that's all stainless in the guts (unknown "heavy duty" polymer in the wheel). 32mm diameter, about the right thickness, fits on the bearing pin. That will do for about $8 a pop. If it seizes, we find plan B. I've read varying opinions about lubricating sail tracks, but universal suggestion is to clean it, which I haven't done. Yet. Ever. Truth be told, there's probably a bit of lake mud in there, especially near the head 🤭. I'll give the bolt rope / luff of the sail a good scrub too. Then I might spray a bit of silicon lube into the mast track, or I might not.
  6. I'm having a terrible time raising and lowering my mainsail. It's just getting stuck. This afternoon I almost couldn't pull the halyard out of the cleat at the mast head to lower the main - I ended up trucker-hitching it off the bow stay saddle for mechanical advantage, pulling all my weight on it, flexing the mast, completely unloading the forestay before it finally moved enough to uncleat. I'm not sure whether the sail is just not sliding in the track, or whether the pulleys at the mast head are stuffed. Well, I know the pulleys are stuffed. They're very old and worn. How big are they supposed to be, to source replacements? Mine look to be 28mm diameter, 9mm thick, with a hole to bear on a 6mm pin. So, with them soon to be replaced - is my sail sticking in the track? I've only sailed in freshwater lakes, so corrosion and salt isn't a consideration, but it's definitely getting harder to hoist. What do I lube the track or sail luff bolt rope with?

    Cartwheeling (nose diving)

    A new angle to add to this thread. I've been thinking a lot about jib shape and power. I've tended to have my jib luff as tight as a frogs bum. There is significant slack in the forestay when unrigged - a loop of cable at the head or tack. Rigged up, the sail stretches until the forestay takes the load, which pulls a lot of shape into the sail. Pulling on lots of jib sheet tends to pull the leech tight, still with a big belly in the sail. Also with a tendency to luff at relatively low pointing angles, because there's so much draft so far forward in the sail. So, lots of power in the jib, and difficult to release power because it gets flappy. I think this is what has been driving my bow down the hole. I raced today (mixed class - solo sloop on my Mari, second time racing in about 20 years 😎) in about 20 knots. Usually that would be serious nosedive risk wind, especially in close proximity of other boats forcing unwanted manoeuvres. And some broad reaching legs that give us all nightmares. I loosened my jib luff significantly today. Just snug on the forestay. That gave me a much flatter sail, much less power forward. Pulling the jib on harder pulled all shape out of it and really depowered effectively. MUCH less tendency to bury a bow. Even downwind. This will require more experimentation. I reckon it might be something that needs changing for different wind conditions - a bit tighter in light air when we want more power? But probably not as tight as I have been using. I wonder if this is something that needs to be more readily adjustable than retying the jib. Anyone done an adjustable jib halyard or cunningham?

    Mk1 resto questions

    I took a friend out for his first ever sail, and he immediately started looking for his own cat. Talked him out of a cheap H14 by finding an even cheaper old Mari. It's not in great shape, but suits our needs as a fix and learn project. First question - the new boat has a different dolphin striker to mine. He has a screw thread on the striker itself to tension the cable (mine has turnbuckle on the cable). Guessing they swapped to the later style for a reason. Replacing the striker cable as a matter of routine, should we go with a turnbuckle cable and ignore/remove the inbuilt striker tensioner, or is a like-for-like simple fixed length cable okay?

    Cat ID please?

    Cheers Darcy. We may have found a Mari in "project" condition, which he can park up next to his other projects while we cover the fundamentals on my boat.

    Cat ID please?

    https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com.au%2Fulk%2Fitm%2F273627382847 I took a friend out on my Maricat for his first time yesterday. He's already shopping for his own 😂 I've recommended he pick up a cheap Mari or Windrush. There's a few H14s around at the moment but I'm hesitant to recommend one (for all the usual reasons that have been covered elsewhere). This one has a sail emblem I don't recognise, but looks half decent. Anyone know what it is?

    Cat rig / sloop rig.

    I usually sail sloop, but on very windy days sometimes leave the jib behind. I use two forestays when cat rigging, one when sloop rigging. I can furl my jib and convert to cat rig if things get desperate, but I don't rig a jib and not plan to use it.
  12. Warm and windy on my day off, so I declared the sailing season open today. Turned out a good day to demonstrate why it's wise to sail off a lee shore, especially when sailing solo in an isolated place like Lake Burrumbeet (near Ballarat). I pioneered a novel way to sail downwind, catching some wind in a billow of mainsail leech while dragging the mast along in the water beside the boat. Hmmm. That's not where the mast is supposed to go. Turns out, although I've been paranoid about checking the state of the plates under the side stay saddles... I haven't taken much notice of the bolts themselves. New and interesting ways for a 30+ year old Mari to fail in service. Derigged when I got to shore, and only had a short tow through the reeds to get back to the boatramp. GPS says I was out for a total of 0.5 miles. Including the wade back to the trailer. Maybe we can open the season properly another day. Once I get some new saddle bolts.

    Pretty sure that's just camera angle. My striker is tight and in good nick. But I'll triple check next time I'm rigged and tensioned just to be sure.

    Off boom sheeting?

    Pretty sure I'm using 10mm. Crappy rope though - the finest BCF had to offer. The nearest chandlery is 100km from here. I hadn't known about threading the blocks properly, so I've looked at some instructions and diagrams and worked out a better crossed-block routing. Seems better. You're right that you get some direct 1:1 effect on the boom until your overcome pulley friction, at which point it starts cranking the boom down as expected. I'd say that's the best of both worlds. You can see it in effect in this little vid from a couple of weeks ago: My biggest problem is that I can't position my cleat far enough out of the way (that's as far down as it can be adjusted), so it's prone to auto-cleating without meaning to. Haven't found a solution to that one yet. I swapped back to conventional sheeting for yesterday's session (see my latest addition to the "cartwheel" thread ), but I think I prefer it off the boom. Might even consider getting rid of the cleat altogether... although sailing sloop solo, it's easy to run out of hands, and a cleat gives some options.

    Cartwheeling (nose diving)

    As Brittney would sing... oops I did it again Some more submarine action yesterday. Quite a bit of breeze (20 knots + gusts at Ballarat airport, about 15km away, maybe a bit more out on Lake Burrumbeet). Solo (~75kg), so I can't blame my forward hand for being too heavy this time. I was dipping the bows all day, so I was kinda ready when it went deep the first time. Dropped the mainsheet and recovered. Second time I was consciously trying to steer through the wind rather than depowering. I rounded up well when the bow dipped, but bore away too soon and sent it down in to the mud. Stepped over the bows when it was beyond recoverable. It seemed to me that the bows were more prone to diving when I had too much boom lift - traveller too far in, mainsheet eased off. Dropping the traveller further out and sheeting on harder seems to pull the centre of power further aft, lifting the bows. I rigged with a slightly longer forestay strop than usual (I made up a couple of options when I re-rigged the forestay after the incident a few posts back), so the mast is raked a bit more than I've done before (which also should have pulled the bows up, by my thinking, unless I'm getting a weird interaction with the jib slot). Lots of downhaul and outhaul on the main. I'd also like to point out that I'm getting plenty of successful sailing in, in between these screwups . And I'm deliberately pushing the envelope, seeing where the limits are, so it's inevitable that I'm going to find them sometimes. I'm just very analytical and like to figure out _why_ :-) Tim
