2008 34T - sling locations for haulout

This is the first time I have done a haul out on this boat.

Is this how other owners end up being hauled out ? It was way off of the sling locations marked on the boat. It appears you either have to hire a diver to thread the sling between the hull and sand shoe, put the sling in the marked locations and risk lifting from there, or perform a dizzying balancing act.

My yard has done it different ways over the years, including putting someone in the water for haul out. What they've settled on is this:

• For launch, thread the sling inside the sand shoe.
• For haul out, they've marked the location at the front of the sand shoe and position the aft sling there. The vast majority of the boat weight is then on the aft sling but it has worked so far.

My boat had no markings on it for sling locations--I don't believe they were delivered with such markings. My lift operator added them for the haul out locations noted above.

My 2006 34T had very clear sling markings. A launch operator ignored them and put the aft sling too far back and bent the sand shoe. The aft marking would have worked fine.

I am pretty sure that operators are thinking full keel at first. I am going to print these pictures and put them in the log book

My yard (previously a MS dealer) moved the hull marking for the aft sling to the Fwd end of the sand shoe / aft end of the keel - They use the new locations for both haul & launch

Don't recall exact location of the Fwd sling but memory says it further fwd than in PugetMike's photo

The locations of the sling are just fwd of the shoe, really close.

It this case, the fwd sling pretty much lines up with the middle of the fwd window and the aft sling lines up with the middle of the (fwd)aft window.

Yes, the fwd sling is also marked further fwd on my boat, the lift operators brought it back to reduce load on the back sling.
They said there was no weight on the fwd sling as marked. Even moved back there is a 10k lb difference between the slings.

Mike that's exactly where my aft sling is now.

If not mistaken I think the fwd sling is just fwd of the windshield which should be roughly the location of the fwd stateroom - galley - head bulkhead.

Seems like mid window would be too far aft???

I think my next haul out will be at a yard that uses hydraulic trailers instead of slings.

When I had my boat surveyed at Van Isle (Sydney BC) they had an awesome trailer that could haul out just about any thing under 70'.

Not sure I see the difference
They still have to set up / afjust the trlr support points to match the boa

There are youtube vids of these things. Basically they act like big bunk trailers, they dont touch the keel. Much like the big forklifts for boats, they adjust their width to stay clear of running gear.

They also adjust their height, they can haul sailboats with no problem.

Gotcha
Different than the hydraulic trlrs I'm familiar with... they have individual support points that are adjusted.

Too bad someone with one of those doesn't set up a business hauling loopers around the fixed bridge in Chicago! That would let other boats get around the loop rather than limiting the air draft to 19'.

OR Chicago could fix the bridge? Call it the Obama Memorial bridge and someone would throw money at it!

There is a discussion thread here about this very topic:

I did not consider the stress/deformation of the hull due to slings - now I have to check for damage I might not have noticed. I did not hear anything ominous but it is still worth a peek.
