Actually they are designed for both in the water and out at maximum rated weight; There are no structural issues provided the lifting slings are properly placed and blocking is done correctly.
Fuel tank level for winter storage.

Apologies if this is covered somewhere else, but where do we find where to properly place the blocking?
(I want to get hauled out with full tanks and want to make sure yard does what they are supposed to)

Yeah that's what Sea Ray says. And the op's manual states the measurements for travel lift slings and also for blocking (usually the same). But the manual also states or implies as empty as possible. Note it also talks about the sling spreader bar, you know the bar that is pretty much never used. As well as putting the boat in a cradle, not blocked. Yes, my manual excerpt is a little older then most and my bottom is 100% solid glass about an inch thick. Which is certainly stronger then the more modern cored boats, but is still relevant I believe.

When talking about a sling spreader bar the intention is to limit the direction of the lifting force to as vertical as possible. A fore/aft spreader is needed at a minimum if lifting with a single point lift like a construction crane. With a travel lift the design makes a spreader redundant because the slings are lifted vertically.
Several years ago (like 8 or 9) I talked to SR PDE at Sikes Creek about blocking up for an extended period. This was for my 400DA. They were anything but concerned. Bottom line is they recommend keel blocking no more than every ten feet and support stands under the outboard chine at the bulkheads, transom, and additional supports for overturning along the sides and bow. That was it; nothing about fuel, water, or anything else.
Regarding spreader beams - most larger boats are hauled with a Travelift in which the slings are splayed outward and consequently not requiring any sort of a spreader. If hauling with a single hook crane then spreaders will be required.
Ah - just saw Henry Boyd's post. I'm a bit redundant.....

Not that I disagree with you, I was just pointing out what was in the SR manual regarding weight. I still don't like the added weight when being pulled out.
Regarding the spreader bar, in the early days travel lifts sometimes needed the bars as not to crush the bow of the boat. I use run a travel lift late 70's early 80's and I was forced to use it at times. But agree, a must when using a fork lift or crane for the most part.

Speaking of spreaders....I'll never forget my first haulout of the 420DA. I had pulled up along the bulkhead and then went into the office for a few minutes. When I came out this is how my boat was hanging as they waited for the yard trailer. Their spreader was too small width and length, and slings to short. They were squeezing my beam hard. Fore and aft the slings were at quite an angle going to the lifting points on the boat. They actually had taken a line and tied it around the aft sling and then to a stern cleat to hold it in place.
As I was standing there doing some 'bitching', I say that because that's what the crew thought and called for the boss, the front sling slipped back almost 4' making the boat and crane bounce and swing and the crew run to get away. I thought there goes my new boat, it's going to drop.
They didn't agree with my 'critique' but they did get another spreader and longer slings. Knowing my boat is not the biggest they're handling I think the new spreader should have been longer yet. These pics are with their new stuff. As far as blocking goes I use 4, the first one being right under the stern.
