Proper stowage of dingy outboard?

Hoping to find the perfect solution with some help from the experienced crowd here on the board.

Our inflatable is transported in the swimstep with the Weaver Davits but I dont have a good way or stowing the outboard.
Often times i have a bait tank on the transom port side, so there is not much room also for a mount there.. love to hear any ideas.
The o/b is not really heavy but as everyone knows from experience, can be tricky not to drop the o/b in the water when dis-assembling from the dingy.
apologize if this should have been in one of the other forums, but i was in doubt if either one was more appropriate than the other.

RE: Proper stowage of dingy outboard?

What size is your outboard? We have a very simple rotating mount on the back of our Livingston that allows us to rotate the outboard into a vertical position when the dingy is hauled up into it's stored position. The mount is made in Canada by Adventure Marine. It is limited to ouboards of 9.9 hp (ours is a 4hp 4-stroke). And it is totally manual. You have to bend down or kneel down and rotate the motor by hand. But it has worked great for us for the eleven years we've had it. https://www.adventuremarine.net/prod...ID=3&do=detail

There is a similar system made by Sea Wise which you can get with hand crank or motorized.

Seawise Davits are fabulous until you get to the cash register. We'd love to have one but we could visit friends in Europe--- several times--- for the price of one of them.

RE: Proper stowage of dingy outboard?

It seems to me to be a very dangerous way to transport a skiff/dinghy. It amybe alright in inland an sheltered waterways but I wouldn't want to be on the coast with that contraption on my stern.
I would also think it is a violation for a U.S. documented vessel- obstructing hailing port and vessel name.

I too use the Weavers and have an outboard mounting bracket mounted on the stern of my trawler near the dingy's stern making for simple on/off.

If you look at my photo to the left you can see it just to the left of the steps from the swim platform.

Jack, to address your concern, for a U.S. documented vessel you can add the*hailing port and vessel name*to the*bottom of the dingy hull so that it is still visible.*

RE: Proper stowage of dingy outboard?

The size and weight of hte dinghy will determine which system is best. The kind Marin uses is for light weight, small dinghies, ones that can easily be hoisted onto and supported by the end of the swimgrid without multipart tackle. Once your combined dingy and outboard weight exceeds what you can hoist in that manner, you will need to move up to the SeaWise system, which has a crank for small dinghies, and an electric pulley for heavier loads. The swimgrid will also need to be reinforced to carry teh extra load.
This method is less than satisfactory for a lot of heavy dingies, as the attachment points on the dinghy will fail, or you will need unsightly reinforcements added to the dinghy to make it work.
Not only the boat name and hailing port must be transferred to the upraised bottom of the dinghy, but also the stern facing white light will need to be raised, so as to be visible to the stern, over the dinghy.
On boats such as a Sea Ray, with no available site for proper davits, the dinghy will need to go on the foredeck, or use one of these methods. For a trawler with a near vertical transom, proper davits are a better solution, and no more expensive than SeaWise.
I recently purchased a heavy dinghy/outboard (750+ lbs) that were on a Seawise on the POs boat. The structural damage to the dinghy was significant, at the stern attachment points.
I have no concerns about the danger from a following sea with davits, but I would have concerns with a flip up system. I have seen several examples of the dinghy catching a wave and the weaver davits or dinghy being damaged. This occurs where the dinghy is too long for the length of the swimgid.
Jack: I agree that this system isn't appropriate for offshore vessels, and I don't recall seeing it in use on any with those pretentions.

RE: Proper stowage of dingy outboard?

Marin,
Thank you for posting that link. I thought I had seen most all of the options for dinghy engine storage but had never seen that mount before. I like it a LOT. I have been pondering the hassle of taking off the motor which I'd really prefer not to do.
I assume you are using that motor mount with weaver snap davits? Are you just manually lifting up your dinghy and motor or using a pulley off the boom? Right now I can easily tilt our 9' rib up on the weaver snap davits and tie off on a cleat @ the transom but it would weigh more with our 6-7hp outboard.

Per the USCG Documentation Center, "The name and hailing port of a recreational vessel must be marked together on some clearly visible exterior part of the hull. The vessel name of a commercial vessel must also be marked on the port and starboard bow and the vessel name and the hailing port must also be marked on the stern."

So, for recreational boats, the vessel name and hailing port aren't required to be on the stern, but merely on some clearly visible exterior part of the hull.

We have a 9' reinforced-side Livingston (you have to have the reinforced sides if you're going to carry it on its side) with a 4hp, 4-cycle Yamaha.* We used to just manhandle the dinghy up into the stow position using a short line clipped to a U-bracked on the outboard gunwale of the Livingston.* We did this for some eight years until the light went on.

I realized if I replaced the boom fall--- which was long enough to launch the sailing dinghy on the aft cabin top but no longer--- with a 120' boom fall, we could use the fall and its multiple-sheave blocks to deploy and retrieve the Livingston without having to move the boom at all.* So what had been a two-person strain job is now a very easy one person job.

We would not use Weaver Davits to support a dinghy any heavier than ours.* Our boom fall system does the same thing as a Seawise Davit less the automatic motor pivoting feature.* But the typical teak-grid swimstep with four mounting brackets is probably not strong enough to support much more weight safely, particularly on an older boat like ours.* A heavily built fiberglass extension-type swimstep is probably a different story.

But this is why, when the day comes that we need a more buoyant, faster dinghy like Carey's Bullfrog, we will tow it and leave the Livingston at home.

And I agree with previous comments that carrying a dinghy on the swimstep in the open ocean is a potentially very dangerous thing to do.

This is precisely the problem I have with going any distance with the dinghy covering the transom.* I read that regulation to mean that the vessel name and hailing port must be affixed to the hull, and not to the bottom of the dinghy.


I assume that your point is that you can affix the name and hailing port elsewhere, so that the dinghy doesn't*obstruct the view, so long as it is permanantly fixed to the boat (part of the hull).

Not to worry.* The majority of powerboats up here carry their dingies on the transom and all the ones that are documented (like ours) have the name and hailing port on the bottom of the dinghy.* Same with most of the ones that aren't documented.* The USCG sees all this on a daily basis and has for decades.* We've been boarded twice--- the patrol boat got our name off the bottom of the dinghy for the radio hail.* It's legal.* If it's not legal then somebody needs to tell Coast Guard Puget Sound.

We also have the name and hailing port on the transom but it's obviously blocked by the stowed dinghy.

Yup, anywhere visible on the hull.

RE: Proper stowage of dingy outboard?

On Moonstruck, the name and hailing port are both on the stern and the dinghy bottom.* Weaver Snap Davits with a Weaver leaver for the motor will take weight off the dinghy.* Our motor is a 15hp 2 stroke Yamaha that comes in just under the weight allowed for the Weaver leaver.

thank you very much everyone for the replies.

i wasnt aware of the USCG requirement and have seen many many boats in the Long Beach areas who carry their dingies on the swimstep, without having the name and port painted on the bottom of the dingy.

my o/b is a small 4hp so i think the best system i have seen so far is this one Marin has recommended. The dingy and the o/b together cant be much over 100lbs so i doubt that there is much of potential for danger.

Thank you Marin,
I looked at the website and it doesnt show how this unit is fastened to the dingy, is it drilled into the wall or?

There are four mounting holes drilled in the mount's*base plate.* You drill the transom to match them and attach*with bolts, nuts, and fender washers.* Good idea to seal the base plate to the transom around the bolt holes and under*the fender washers*to prevent moisture ingress.* I used either Sikaflex or 3M 4200 for this.*
