I'm doing an Ethernet LAN for a commercial boat that uses a composite cable with fibre optics for the Ethernet with copper conductors for the ELV power. Kinda neat pulling a single cable, but you need fibre interfaces on your edge devices which sadly isn't that common yet. POE was a game...

The joys of a steelie? Don't need no stinking additional engineering when the hull is near impenetrable. Mind you, a rudder post open to the interior sans a rudder could still make for a bad day.    

A free standing mast will tear a big hole in the cabin top when it fails  bad idea  Geez Slug, that's a helluva broad generalization. That like saying all deck stepped masts are bad.    -aft watertight bulkheads are indeed a good idea.  -bow  waterproof crash bulkheads are a good idea -A...

This. Throw in dual rudders and I think this should be mandatory. You can't hide it/them behind the keel and the cant adds depth and width, dependent upon heel.   Edit: for offshore that is. Bay cruising is different of course.  

ON my deck stepped mast, there was a hardpoint low on the mast and another on the deck. When I quizzed the French at commissioning what it was for, Antoine produced a short dyneema strop, it was the tether to anchor the mast base to the cabintop.  :( . Embarrassed to admit I hadn't thought of...

I had one of those horror trips once where I spent about 40 hours travelling between three continents and 5 nations before arrival in a wee little South American airport at some god forsaken hour. I  grabbed my bag from the trolley, turned around and ran straight into my brothers ex girlfriend I...

At least Tasmanians stick to two legged creatures. Now the Kiwis..... 

In a world of 6.6 billion people, it does seem hard to believe. The theory of six degrees of separation contends that, because we are all linked by chains of acquaintance, you are just six introductions away from any other person on the planet. But yesterday researchers announced the theory was...

I did some time on a Crowther 60' cat back when it seemed all the rage to keep pushing the mast further and further back (tiny main/huge headsail/huger...er kites) and increase the forward sheer to something resembling a ski jump.  Going forward to the bow in any decent swell was rather...

Thanks Estar, glad I hadn't just imagined it. I remember getting hammered on a Swarbirck 42'  in that area for a sold 24 hours, the waves were like falling off cliffs. One thing that stuck with me was how good the dual canted rudders were for bite. As you come over the wave crests the boat would...

Thanks very much for the very informative response. Albeit I need more coffee to absorb the chart, is the vertical axis intended to be the AVS? 

G'day Mike, I thought the summary from the 98 S-H was the yachts getting into trouble was more about the locale the boat found itself in rather than the seaworthiness of the boat? I do believe there were some new boats that simply were too focused on speed vs manners for those conditions but a...

Did I mention how good this thread is? Just wanted to say thanks to all of you chaps, its enjoyable, stimulating and thought provoking just listening.  

Yep, my dislike about keel up mode under sail as it seems illogical from a forces point of view. My keel head is only a single bolt through an eralyte bearing, so the mating of the keel box and head have to be structural, ie: it must 'fix' the keel in place. In the perfect world, if...

The big difference between the Pogo and a lift keel is where the ballast position ends up. "Lifting" a board on doesn't move the ballast fore or aft. The 12.50 'swings' the ballast aft 3mtrs. Pogo's standard advice is keel must be down when sailing, which makes a lot of sense selling to a...

Yep, just don't forget those pesky plotter colours stay the same....

Hiya FKT,  That indeed is a problem. My new favourite catalogue..... We've just finished restoring an old 1940-50's pommy lathe and milling machine that was gifted from a farm.  It came with every head and accessory known to man , so we have been cleaning and sandblasting and restoring...

:lol: Thanks mate, I will make sure I take you up on that, I would love to go for a ride on your gorgeous girl one day (boat that is), cheers!  It surprised me how much cheaper motorsports have become. a complete injected/blown big block costs less than the price of a new sail wardrobe ...

G'day Veeger, Yep, same, nothing against the boat, I feel thankful for the 5 years I did get. I was pretty chuffed that the only defect at the time of sale was the boom bag was a bit tattered and the cabin stickers were faded, everything else was working like a charm.   Thinking back now, all...

H Misbehavin, Yep, she's sold. I'm playing with some past life motorsports stuff, I'll give it a few years then maybe see what happens. Hi J/V, Sorry, I meant mandatory ie: damn good idea.  Before we took collection I had some expert muppet convince me that a Class 40 hull will heave to like...
