I’m thinking of buying a Hunter 41 ds that was built with 2 qtr berths and ‘remodeling’ to make one queen. Anybody got a problem with that? Structurally speaking

If there is that model Hunter with the large Aft cabin then, yes, you can do it.

If not then don't as it maybe supporting the cockpit.

Examole, my boat comes with one or two Aft cabins.

Might be nice to keep it having a sleeping space and a garage or a third sleeping space
Do you need an extra large bed?

What the pictures doesn't show is whether the model of the boat with the single aft cabin has a different structural layout than the boat with the double aft cabin. That centerline bulkhead would greatly stiffen that portion of the boat. In theory, there would need to be something structural to replace that bulkhead.

Originally built with 2 qtr berths and ‘remodeling’ to make one queen.

Check to see what was done when the partition was removed.

Maybe contact the manufacturer.

I have to disagree with Jeff on this one. The pictures absolutely show structural differences between the single cabin " Owners Version" and the double cabin. The single cabin gains a deep lazarette to port and the hanging locker is aft of the cross ship bulkhead. These two features would definitely add rigidity to the cockpit floor of the deck structure. I can't imagine that a production boat builder like Hunter would have different deck molds for the same hull. I would agree with Jeff that simply cutting out the bulkhead between the 2 cabins without compensating for the loss of structural rigidity would not be a good idea. If one however wished to more or less duplicate what the Hunter Owners Version DS41 did structurally by adding a storage area in place of the lazarette and tabbing it into the bottom of the cockpit deck as well as the hull that it would be a reasonable modification. Whether this would be a good idea or a cost effective solution is an entirely different matter altogether. Since the OP stated that he is "thinking of purchasing" a DS41 I would suggest that he take a serious look at this modification as it compares to simply finding a factory owners version.

After saying all of that I still have 800 words to go to illustrate a point ??? Guess I'll never make it as a writer. Darn, another fledgling dream dashed.

In the end I bet it is less expensive to just buy an owners version to start with after the mods get all paid for, even if you do it yourself.

But assuming the 44 is like my 410, the only thing that portion is supporting is the liner and if it is one piece, there it isn’t really supporting anything.

But the simple thing is to call Hunter as the designers are still there.

While I agree that the pictures imply some of the structural differences between the two layouts, and that the components that you point to could potentially help stiffen the hull and cockpit, my point remains that the photographs may not actually show all of the structural differences between the two boats. I will also note that companies like Hunter often did have multiple hull molds, deck molds and pan molds that accommodated different models.

For example, the shoal keel versions often had a different keel stub and pan than the deeper draft versions of the Hunters. Similarly there were different pan molds for the single and double head versions of the same design as well as aft cockpit vs mid-cockpit versions. In theory that could be as many two separate deck molds and as many as 8 sets of pan molds for the same basic hull design.

When you have manufacturers producing large production runs of a single design those kinds of variations are not that big a deal.

The pan mold was the first thing that came to mind. I'm just assuming that's what Hunter uses for hull rigidity, but would highly suspect there are different between those two models.

Despite this point, renovating your boat bedroom is nothing like doing so at home. I'm 100% certain that all kinds of frustrating, unanticipated gremlins would appear in a project like this.

Perhaps the most significant issue is resale. Unless you're a master cabinet maker, it's unlikely anyone would want to buy the modification. Even if done perfectly, you'd still have to prove it was structurally sound.

Contacting Hunter was the best advice above.
