Davits are quick handy and can be used as extra storage (garbage bags) when inshore cruising.

They make docking more expensive as they are counted as LOA when alongside.

Offshore the chance of a wave filling , and wiping off the setup exists, so an on board storage spot must be found .
A condom dink can be deflated and stowed if the boat has a good cockpit , a more robust dink will need a hoist to bring aboard.

The more I think about this the more I believe that the crane is our answer.
I really do not want to lose the space on the swim platform to something as large as a dinghy...

I vote for the crane setup, although that deck space would be great for some big solar panels.

However for the anchor out cruiser the dink is as important as the horse was to a cowboy.

Everything depends on how you use the boat.

We are definitely the "on the hook" type...
The dinghy is an essential part of cruising, no question! We have a 10' Trinka that accompanies us 99% of the time. I am sure that the davit's would be faster to launch and that is one reason we considered them.

We have time to figure all of this out!

Three additional factors to consider.

Dinghy davits lengthen the boat for many marinas, incurring additional charges.

In many areas boaters partially raise the dinghy out of the water each night for security purposes. You cannot do that with most cranes because you cannot suspend the load.

The davits displayed look like they and the dinghy would take a beating in a following sea.

I prefer my crane.

Keeps the transom and swim platform clear for boarding and docking.
Dinghy is more safely secured on it's upper deck cradle in bad sea conditions.
Very easy to store the dinghy at night on the cradle with crane still attached.
Reduced risk of theft or vandalism on the upper deck.
Crane can be used for loading other heavy or awkward items from the dock to the boat.

Davit's or crane?

Crane. A week after you install the davits you'll wonder what was I thinking. Depending on the sink you may want to stow it upside down and keep the motor down low perhaps in a laz to keep it more protected. Crane can also be used for anchor retrieval moving batteries etc...

I'm still kicking this question around. For those of you with heavier dinghies (400+ lbs) that you carry aloft, do you notice or worry about stability issues? Do you carry it up there in heavier seas? I know the answers will be boat-dependent, but lots of people warn against it generally . . . and I want to carry 500 lbs up there safely.

I would choose the crane. This keeps the swim platform clear of hardware and the dink itself.

When using the dinghy frequently, for example during summer cruising, you can tow it and have it always readily available for use while having the space free in the flying bridge.

For longer runs or when rough conditions are expected it can be hoisted and out of the way.

Some insurance companies will not cover a dinghy when it is towed. Check first

Crane. Most versatile and who needs the dingy in the way all the time.

We have a crane, and for boats with enough deck space, it seems like a great place to store the skiff.

I can deploy or retrieve the skiff in less than 5 minutes. Generally I leave the crane in the "up" position, attached to the skiff's harness when cruising.

Our skiff is a Zodiax YL340 with 30 HP outboard. I think it weighs around 600 lbs or so.

We have experience with crane, garage, and dinghy on platform. None with a davit as it's really not very conducive to where we use a boat or our speeds or the size RIB we use.

We would only personally choose the platform over crane given ideal circumstances-a platform designed for that, a platform that raised and lowered a good distance, one that was very wide, and one on which the weight had been tested as to it's impact on ride and performance. Also, just lack of space for a crane and dinghy.

Otherwise crane. That boat appears well set up for a crane. As to the question regarding stability, I'd be more concerned with the impact of it adding weight off the back than on the upper deck that was designed for it.

On that boat unless a compelling reason otherwise, we'd go for a crane.

As to the comment of raising out of the water, while putting one in chocks on a platform that lowers is easy, a properly set up crane is just as easy as most davits I've seen used. Now part of that is proper lifting cradle for the RIB. Plus most cranes can handle more weight than davits.

Years ago I checked with Krogen on the stability issue. Was told the design was for a maximum of 750 pounds total on the upper deck including helm chair, dinghy cradle and all equipment. This is for a Krogen 42.

Crane boom position

One major item to consider is the crane placement and boom length. I had a 43 Marine Trader CPMY that I installed a sun deck crane on. It took a CAD layout to assure the reach dimesions. We had a friend that could only side load his 11' Whaler. If in a double finger slip the boat had to be pushed back to launch and retrieve. Needless to say, did not get used much. several photos are show my setup. My wife did have to push the Logic off the swim platform about 6" but it worked for us.

Nick Jackson Davit/heavy dink and motor. Easy access via swim platform/transom door on starboard side. A crane/roof storage with side launch would make the dink inaccessible in most marinas much of the time. reports of roof mounted dinks degrading roll characteristics of the mother ship. Finally I've watched some downright dangerous launches of roof mounted dinks in rough anchorages

That is a great davit. Very strong, and easy to use. However, you can't walk from the starboard side of your swim step to the port. If you need to port tie at a dock and the dinghy is up, you can't access the dock from the swim step.

Here is a photo of my stern. You can see the Sea Wise davit on the starboard side (looks like a tripod). Ignore the covered grill that appears above it in the photo. I have a huge swim platform, but I can easily walk between the back of the cockpit and the davit so I can step off the swim platform to the dock without a problem with the dinghy in place.

Think I'd consider both. (Maybe even a removable version davit system (St. Croix?), if there is one that will hold the weight.) Seems like each system has pros and cons, and sometimes I'd want to elect which pros I'm using at any given time.

How do you get up to the boat deck to control the crane?

FWIW, our cantilevered "crank-on" system on the swim platform works decently enough. It's offset far enough aft that we don't have much issue with boarding, and we can walk between the tender and the mother ship's transom. OTOH, I have to worry a bit more in following seas and especially when coming down of plane. I could have added (or still can add eventually) a power winch, but that so far would be too much trouble. One of our cons is that it's a side-loading system, so when my port-side dock neighbor is home, or when we get an uncooperative transient slip somewhere, I have to do some extra stuff to launch the dinghy.

Whatever one gets, practice with it. Get proficient and prepared for less than perfect conditions. Then recognize the conditions in which it's best to do nothing, just sit and relax.
