    Measure the longest stays (Forestays), if they are less than 5.5m, you will have to have the bow of the boat uphill for the mast to lean far enough to stay up whilst you attach the side stays.

    The long ones go on the bow, the short ones on the side. The large D shackle on the mast should have the long forestays in the middle then the shrouds on the outside. Rig the mast shackle then put the forestays on. Lift the mast so it's standing upright on the ground just in front of the mast step on the front beam. Once you have it steady lift and slot the base into the mast step. You should be able to do this in one smooth motion and just let the mast fall back with the forestays stopping it falling on the ground. Once it's like this you should be able to then attach the shrouds. What I've done in the past (and still do when it's windy) is to attach a rope (eg the mainsheet) to the halyard and then pull it on so that it is tight. The triangulation of the forestays and the haylard will make it safe long enough to attach the shrouds. In the racing world we use forestays at 5.5m and shrouds at 5m. This gives a good mast rake but if you've got an old sail the boom may be too low. When you start sailing and keep nose diving (going down the mine!) then you should consider this extra rake and get a sailmaker to put a D ring on the back of the sail about 150mm up from the old one. Would help you a lot if you could find a local club that has maricats. Good luck.

    Krispy, still plenty of parts. 1988 would be a Mk2 (Traveller track is part of rear beam extrusion, not a separate track) Give me a call on 02 43591729, for a list of things to inspect.

    Sailor Zane Bradbury repeatedly went down the mine at a recent Humpybong yacht club race day .. No attempt to release the mainsheet or jib.. just this huge grin on his face.. Apparently he doesn't bruise.. unlike the rest of us.. I would love a Mari to take him on when the seabreeze kicks in, Moreton and Bramble Bay get a vicious chop and the A class, Nacras and Lasers pack up and go home.,

    You can do things to old sails to get some life out of them. One is to cut the bolt rope from its anchor at the bottom ( a few stitches). I did this to my Eastwind sail and the rope disappeared about a foot or so up the slot. A tight rope means the luff is crinkled and the body of the sail falls back which isn't fast. +1 on the rudder. Look up Ackerman steering. This is why the tillers are bent inwards. There's a measurement (which I don't understand!) but on cats your hulls go at different speeds and radius when turning. Stays 5.5m front and 5 rear. Remember that the tighter you have the mainsheet the tighter the jib luff will be. I would think you'd be in front of the Getaway and the H14 but behind the 16's. The Sailing Australia yardsticks should be an indication. Just as a guide we did a long race at Speers Point on Anzac Day. The line winner was a Maricat Super Sloop (foam) and was quite a long way ahead of me (2nd over the line). Once they'd unstuffed the handicaps (they did me as a SS foamy!) I won it. My calculation was about a minute ahead, Mark was a good five minutes in front on the line. I also noticed Mark (SS) sailing off the start line with jib literally flapping in order to get height. Once clear of other boats he bore away to use the jib for speed. Sand the hulls - don't need to go too far but maybe 120 then 600 makes them smooth. Same with the rudders they have quite a large whetted area - fill in the chips with Epoxy Filler. They talk about toe-in and I think this refers to hulls as well. I've seen rear beams that have the bolt holes drilled oval so the gap can be adjusted. Not sure what the gap should be though. Tramp should be as tight as possible.

    In my experience older tired sails are significantly slower upwind. I have a couple of older mainsails (I sail cat rigged) that have successful histories, but with my newer Chris Cairns sail my Maricat is minutes faster around a course. Upwind the newer sail allows me to sail higher and faster. I am overweight so need all the power I can get. A new sail is probably the best go-fast investment you can make on these old girls, along with some mast rake, and aligned and no-slop rudder system. One of the best Maricat sailors from the early days, Richard Eveleigh (one of the contributors to our tune up guide) had great success with a black Lee sail. He was super fast upwind. He now sails a foiling A class.

    The clear plastic tubing that connected my tillers to my crossbar (over the top of the broken flex links) went yellow and stiff, then split. Now I have new clear plastic tubing. The closest size Bunnings had was a bit loose, but nothing a couple of stainless hose clamps couldn't fix. Good for toe-in adjustments, I'm sure. I like the look of Pete's solution above. What are those ball joints meant to be from?

    I would use some older Hobie type ie 14 or 16 in used condition but too date non found I have been asking around a little , one other idea is too use the Nacra parts from Murrys in the USA I have included a pic only about $50 usd

    Another tuppence worth: Google "ackerman steering formula" and it shows what Ackerman really is. I think the tiller setup on new Maricats has nothing to do with Ackerman since the tillers are straight just a marketing ploy to make you pay more than your boat cost you just for a rudder setup! One of the reasons that the old format tillers are bent is so that an Ackerman geometry setup can be achieved. Google search will eventually find the right setup for cats. Can't remember how it worked but I think you take a line from say the shrouds to line up the rudder when they're hard over. In Whitworths: https://www.whitworths.com.au/riley-stainless-steel-transom-gudgeon-1-4 are the rudder pintles that we use to hang the rudders but I have a couple bolted to the tiller to attach the cross bar to. $7.80 each compared to $14.95 for the bungy joint version https://www.whitworths.com.au/riley-tiller-extension-universal-joint I think this is a good one though, no play but you'd need to keep them out of the sun because they just snap off when they've been out a few years. My understanding of aligning rudders is you do the ackerman effect by bending the tiller in on both sides. To line the blade up take a line from the bow back to the stern (middle) and line the blades (sticking straight out). Make sure they are both straight. I just bent them in (ie twisted the tillers so they curve inwards) and then rivet them to the rudder case. Can't remember whether you should rivet from the side or the top - side I think - less movement that causes the rivet to break. Mine seems to be right now - I can actually tack most of the time!

    Sorry, its all been sold a few months ago. I should have come back and updated the post sorry. By the way. I have seen the cat sailing again in the bay which is good to see.

    Hi Phoenix, looks like Mark has put the Mari on the back burner or in the to hard basket (nothing recent on his blog). Keep us informed, on this site, of your progress, I'm currently racing a reclaimed/rebuilt Mk1 and find very little difference in its performance compared to current model and it is almost bullet proof in comparison, looks like it could go another 40 yrs.

    Mando give me a call, (02) 43591729 I have repaired/rebuilt countless Maris for friends and club members, and know all possible problems and their causes, advice free. No need to reinvent the wheel it is much cheaper to learn from someone els's mistakes.

    Your transoms look okay, are the bottom of the hulls okay? if they havn't used beach rollers you should check to see the gelcoat hasn't been scraped off by being dragged on the beach.

    Those cracks just look like paint/gel coat cracks. I don't know much about this sort of thing but I'd reackon you could probably sand it back and cut it in.

    Oh there's some funny shit on this topic. I'm only new at this and I haven't been game yet to go it alone with a jib cause I dumped my mari just with a main. I've never even seen anyone else sail a catamaran yet but I'm sure having some fun.

    I've seen Macca cartwheel. And me as I was laughing so much. A maricat nosedives easier than anything I have ever sailed. [This message has been edited by Emmessee (edited 21 May 2004).]
