      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.

Schionning cats are fast

Newport to Ensenada race aboard Bill Gibbs Schionning G Force 1400. Much more comfortable than Afterburner and hitting similar boat speed numbers

They look good. Not had the pleasure sail one yet but they are high on the bucket list.

What great looking, great performing boats. When do the dagger boards go down?

Great video! I would be reefed down and moving a comfy 18 knots.....

Sail change was from screecher to our new top down furler spinnaker or whomper. Like a code Zero but loose luff. Pity the upper lashing failed after only 2 hours and sail fell down into the water. No damage but we had to hoist our regular asymmetrical spinnaker for the rest of the race. We are looking into why the chafe failure of the lashing.

How'd you like that automatically connecting headboard system? :D:D

Auto headboard is great, we originally had to send someone up in a chair to connect the head to the top cars.

We have a quick release pin on the second batten car so it all goes up and down easily.

Great video thanks.  At 5:35 there is a shot of what looks like the side stay attachment?  How does it attach?

This is how the shrouds used to attach to the boat at the lower lashing, however it came loose and we almost lost the rig. Now it is lashed through the base.

Boards go down maximum 5ft below the bottom, upwind all the way down, reaching 3 ft down, downwind 2ft down

Makes sense. I guess there wasn't much upwind in the video.

No wonder it failed, thats a Strange way of doing it... the usual way we attach shrouds to a composite chainplate like that on this boat and many others built like that here in australia is to cut a slot in the center top of the chainplate laminate just deep enough and just wide enough to accept the end of a rigging screw. You then pass the bolt through the entire shebang picking up the rigging screw halfway through.

This boat seems to go quite well, no doubt helped along by the rotating mast and a decent set of sails - most of the schionning boats here dont get rigged with a rotating stick and subsequently never see those speeds... great boat and great vid :)

Groper, quite a few Schionnings in Aus got wing masts. The original Forza, and another made by SJ marine in Fremantle that I have been on. Both were used primarily for cruising and  both these boats had their wings locked off permanantly to stop the rotation. The one built by SJ marine only got 600nm on its delivery trip before it had the permanent lock central treatment with large stainless structure.

For a cruisers it creates problems that most just can't live with.

The reality is it makes only a small difference in performance as seen by the IOMR treatment it receives. Infact the IOMR handicap was recently reduced to half the masts surface area to appease the squealing rotating mast owners.

We like the rotating mast for racing but the issue is the leeward shroud slack (forestay and 2 shrouds hold up the mast). We now have a lot of shock cord to take the slack but have to use a slack sucker line to a winch when motoring to prevent the rig moving too much. 

The problem with the original shroud failure was that the lower pin was secured with a screw rather than a split pin. The rig movement must have loosened the screw to fall out and the pin worked it self out.

New walk-through video of the G-Force 2000 if anyone is interested. :)

Nice video - pushing pretty hard! Schionning's are fast, there aren't many boats that are that comfortable that go at that speed!

 

I didn't find much benefit from the rotating rig on a similar boat when it went from rotating to fixed - I think the benefit drops as the size goes up, the proportion of the mast area to the total sail + mast area starts to get pretty small.

 

Good to see you guys having so much fun!

Hi Ben,

can you give us an idea behind why the single wheel setup?

Given it's an evolution of the first boat, the focus on lightweight (inc carbon dunny), alternative propulsion etc in the build, I'd have thought not having twin wheels would be a step back performance wise? The cockpit does look comfortable though.

(My own 9.3 has only one wheel, which is centred, I like the ability to look over the cabintop.).

Nice boom furling idea too.

Congratulations on a great looking boat.

Lashed through the base... Is it a temporary set-up?  You're not concerned about chaffing the lashing?

It started as a jerry-rig repair.  After a thousand miles, we took it apart and added SS end caps with nice entry radii.  The anti-chafe tube may be overkill as we have seen no chafe on inspections.  Did both sides to get rid of the heavy old SS fittings.  Have another 3,000+ miles with no problems.

Hi Deano,

Purely owner choice on the helm set-up. This was technically a custom design with the owner making a small number of changes over the original 1800 'KATO' (she had single helm too). It is now offered as a standard G-Force but dual helms would be included as a standard option. :)

Hi Ben, it was mentioned in an article recently that there was a smaller (than 12m) Arrow in development. When will this eventuate?
