Twister Owners - help

[JRCO26]

Hi there, I own an all glass Twister down under in New Zealand, and she is getting hauled out tomorrow for first time in the short time I have owned her.
The Haul Out people want me to clearly mark where the slings should go.
Anyone that has owned or does own a Twister - do you have some tips to provide me on where to put the sling marks?
Thanks in advance....

Looking at similar long keeled boats, I would start with 1/3 from the bow & no more than 1/4 from the stern. Being less weight in the bow it should balance like that. One would want the front strap to hook around the front of the keel. The 1/4 from the stern will easily clear the bottom rudder pintal in the keel & you want it to be behind the engine area. Explain the situation to them first. The boatyard should tie the slings to stop them moving back or forward & if there is an issue when they lift they will see it & lower the boat & re adjust. Assuming they are reasonably competent that is

On my wooden Twister the aft sling sits just forward of the rudder on the last 6” or so of the keel. This aligns just forward of the cabin/cockpit bulkhead. I wiggle the rudder to check the sling is not touching the rudder once the sling is “nipped up” prior to lifting. You could perhaps go slightly further forward, mine sits here to clear support blocks on the trailer. The forward sling is less critical, somewhere in line with the fore hatch. However over the years (all 40 of them!) the marina has always tied the forward sling back to prevent the sling sliding forwards and perhaps over the bow. This rope is made fast at waterline level and then taken to the sheet winches. Not on a Twister, but I have seen a sling slid on a similar shaped boat - nasty ?.
Hope all goes well.

Beautiful, thanks so much Rich

I think in line with the bulkheads., eliminates compression. You would get an answer within a couple of days from the TA.

Put your hand on the tiller as they snug the rear sling. If it moves the sling is too far aft.
Back of the rear strap needs to be at least an inch forward of the cockpit bulkhead. This is the absolute limit.


video of this. First attempt was too far aft!

You mean if the aft sling moves as you wiggle the tiller...?

That video is great - going to take a screen shot and show the haul out guys tomorrow!
Thanks Buck

When they snug the aft sling, if it is bearing on the rudder you will feel it on the tiller.
You can see in the video that even the second time the sling could have been further forward. The CofG is well forward as seen here:


That dot is the centre of buoyancy and the CofG will be directly above it if she's on her lines. So the rear strop can go anywhere behind that dot and she will want to tip forward.

It all went well, thanks all

Good! I know nothing about Twisters, but was going to mention replacing the log impeller with the blanking plug. However that may be so obvious as to be a waste of electrons...
