      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

Seriously where is this? That way that boat is blocked is just down right sketchy? Clearly they know what real jack stands are as there is one in the front. But ahead of that is a 4x4 for the bow and some kind of fucked up looking steel berms for the stern and nothing mid ships?!?!?

It balances alright. But I agree the support could be a lot sturdier. Midships she is supported by the ground with two shelves.

Works for the F-117 stealth fighter

 

News to me that Catalina has an optional quadruple redundant fly by wire system to run it though..

????

Yeah right.. Catalina yachts are the most technological advanced ships in the world that needs quadruple redundant fly by wire systems.

I have the same installed in my beetle.

I remember some Catalina 30 owners complaining about weather helm and some yahoo built these rudders for that "need" lol. Rather than learning how to sail their boats this was the option. What a kelp catcher. ( I am former IC30a commodore )

It doesn't need proper stands because when it falls those fenders are going to protect it. Besides, that rudder must have some sort of special power to avoid bad things happening to the boat - kind of like the twits that put tin foil pyramids on their head. What other logical reason could there be for that abomination?

I think someone misunderstood the twin rudder concept.

 

Either that or they were on acid when the lesson was given.

Benbob once said about a US AC team and their attempt at a winged keel ...." only good thing about that is, it creates more area for barnacles to grow on it"

Believe it or not I built model yachts with rudders like that back in the 70s. Worked a treat but not that sure the concept scales up...

There was an article about the concept in one of the sailing rags back in the 80s or 90s. They used a Catalina 30 to test the concept before scaling it up to a bigger boat. I'm guessing this is the test bed itself.

 

The idea was to give better control when heeled and make it more difficult to wipe out. I'm surprised it's still on the boat some 20+ years later.

You have hit the nail on the head for just about every "sail handling system" out there.

 

Will some cruising expert please explain to me how in-mast furling, in-boom furling, or roller reefing is faster or easier or more reliable than regular slab/jiffy reefing?

 

Or how genoa roller furling if more reliable than brass hanks.

 

I'm willing to completely ignore sail shape and efficiency and safety because I know those points are impossible to make for those wonderful "sail handling systems."

It's not more reliable, but easier and faster to handle. Especially if you sail single handed.

I've never heard anyone say roller furling was more reliable than hanks. It is simply more convenient - MOST of the time. And then it is not.

 

And I am sure this rudder is great, as long as you dont need to change your heading.

Fixed for you.

I'll race you.

 

You on a boat with any fancy improved reefing system you think best.

Me on the same boat with a sorted slab/jiffy reefing set-up.

 

The race starts with both skippers in the cockpit, steering by hand, sailing in normal trim.

The race ends with both skippers in the cockpit, steering by hand, mainsail now reefed.

It's no contest. All roller reefing sucks for sail shape. Period.

 

On the other hand, roller furling is way way easier and faster. Note that racing boats use it to great advantage...

Of course, but I've yet to see a Catalina 30 with multiple forestays each with application-specific sails.

 

I see a 135% high-clewed genoa that has been roasting under UV for a decade, Sunbrella UV covered flogged loose and rotting.

Is it different in your area?

Haha! No, that's exactly what we see.

 

Last year there was a boat out there on mooring with a shredding rollerfulred genny. For at least a week. Just kept shredding. Came loose in a blow. Nobody was responsible for it so it just flogged and flogged. Credit to the Catalina company for building a rig that could take that without coming down ;-)

It's not for nothing the VOR 65 sail with 12 sails. Changing sails in the long run gives more speed.

But for touring, roller reefs are just fine.
