    Catamaran steering linkages

    Whichever way you go about it, allow for Ackerman effect. Not two parallel tiller arms with a link bar. I know, a link bar doesn't work for you, just trying to illustrate. Cheers
  2. This is a common symptom with delivery boats that have sat on a mooring for a couple of years, unused. All brands, all ages (except new, never delivered a new boat). An oil change fixed it in every case, though it may take a couple of runs to clear it. You may have a different problem but it's worth an oil change to find out.

    Engine Swap Anarchy - Gas Palmer to Yanmar 2GM

    You'll be fitting a good quality diesel filter. Get one that has two inlets and run your return line to the filter. That's also a way of avoiding the danger with two tanks, where you may be sucking fuel from the starboard tank and having the return line going to the port tank, which will overflow if you're lucky, or bust the tank if a bug has taken up residence in the breather. I've seen diesels that returned more than 50%, don't know about your 2 GM.

    Struggling with low speed manouvering and docking

    Thrusters would be a last resort. Can you rig a tackle to allow the outboard to steer somewhat less than the rudders? Your cat will maneuvre more predictably astern than forward at low speed. More predictably for a car driver. We had a 45 ft cat with a single 35 hp Yanmar in a central pod. For a while I had the extended stern-drive leg steering with the rudders. Worked fine but when I tried it with the stern-drive locked, that worked fine too so never bothered with it again. Same marina. We always came in stern-first. A single 9.9 is marginal but, if you can learn to live with it, you'll be saving a lot of aggravation and the horrible sensation of overload confusion when things go pear-shaped. It must have worked for someone. Cheers

    uh, a jib traveller ?

    I put a 3 metre curved track on the bow of my 9 metre cat, with the forestay and tack on a traveller car. It enabled close sheeting with an overlapping jib, without compromising the centre cockpit and dodger. Also adjustable for running / reaching. Sounds dodgy but, with a fixed inner forestay, sailed 25,000 miles without mishap. Ok, tore an upper spreader out on a dark, rainy night in the middle of nowhere, a mishap but not related. I stole the idea from a J-Cat I'd sailed on. My current tri has a self-tacking jib track from a Soling, works a treat tacking in our tight bay.

    Rapid Disintegration of Saildrive Leg

    If you don't know your way around a multimeter, get an electrician to check the integrity of your negative cables, especially if each engine has a separate battery / bank.

    Testing a Simrad TP30.

    Rather than pressing buttons to make it extend and retract, power it up and rotate it horizontally to ensure that it extends/retracts and see whether you may have to reverse its response for port or starboard operation..

    Repairing holes from obsolete hardware

    What Midday Gun said. Light abrasion of the epoxy and polyester/qcells/cabosil bog or just car-bog, which is just polyester bog with accelerator added, soft to sand, very fast, use in small quantities. If there's no need for bog (if the remaining cavity is shallow)a spot of flowcoat to match your existing gelcoat. A repair kit is probably flowcoat, rather than gelcoat, so it will sand okay. Gelcoat cures with a tacky finish so it needs wax-in-styrene added for this application. That's what flowcoat is. Probably too much information but it's raining outside, what else am I going to do? Cheers

    Well, at least he began.

    Manual inflation PFD

    Thanks. I'm not inclined to trust equipment any more than I need to, hence my question. I maintain my gear but there's no guarantee that the bottle won't come loose, have an imperfection or be empty. If I'm offshore and accidentally fire my PFD, I'm stuffed because I won't have a spare bottle (airlines don't like gas bottles unless they're part of the PFD). I'll probably fit an extension tube to the inflator so that it can be blown up manually. The extension will have to be removable so that the non-return valve can be accessed to deflate the PFD. I'm aware that in cold water, I'll be struggling to get a breath, let alone blow the thing up. Cheers

    Regatta Starting App / Timer IPhone IOS

    I prefer an audible countdown so I'm not taking my eyes away from the situation. Set the volume so that you're not counting down for the whole fleet. Regatta works for me. Cheers

    Manual inflation PFD

    My PFD is a Kru Pro Sport, rated for offshore with hood, strobe, crotch strap and harness. It had auto-inflate, which I've disabled because most of my sailing is on my trimaran. It still manual-inflates with a pull of the toggle. It also has manual inflation by blowing into the mouth-piece but this is inaccessible unless the zip has been opened, either by the gas bottle or, maybe, by a lucky finger finding the weak point in the zip which, on mine, is out of reach on my shoulder. This arrangement isn't unique. Looking at a few PFD's on the market, it seems common. So, if I go in and my gas inflation fails, I have a problem. If I have to, I'll modify it to expose the inflator but is there a simpler solution? Thanks in advance.

    Considering a cruising cat

    I put a Yanmar 27 in my 45' cat, in a pod made from a canoe molding. The engine was under the saloon table with good access. A long tail-shaft went to a Yanmar stern-drive, which had a 750mm alloy extension to get it well immersed. The extension was full of oil to the level of the top housing, so a bit of weight. The stern drive could be raised for sailing and for maneuvering in shallow water (low power) and, initially, the stern drive was linked to the steering. I found that steering the stern drive was not needed, the boat maneuvering just as well with it locked. The boat steered equally well astern, usually with the board (only one) raised. A mini-keel cat would get some benefit from two engines. The first revelation you'll experience with a cat is just how easy everything becomes after living with monohull sailing. Good luck with it.

    Sydney To Hobart 2018

    I just spent two hours trying to read faster than you blokes can write. Thank Christ someone started a new thread. It's like running up the down escalator. Plenty of wind here now, NW gusting forties. I see Tasman Island had NW gusting 66 knots earlier. That must be fun around Cape Raoul.
