Outboard bracket for \"sugar scoop\" stern?

I am considering fitting a lifting outboard motor bracket so that if the main inboard engine fails, I can at least use the OB without having to have it attached to the dinghy.

Does anyone know of a lifting outboard motor bracket where the part that fixes to the boat is adjustable for the angle of the transom?

Thanks for any help or advice.

This is the arrangement on my Dehlya 22

The engine is attached to the bracket which has 4 wheel running in the alloy track. It is pulled up by a 4:1 block and tackle

If it a true sugar scoop with a bathing platform then a metal bracket bolted through the platform with a wooden pad for the outboard would work. Often seen on bathing platforms on small mobos. What size outboard and what size boat?

Point taken - its a Hunter Channel 323 - 32ft - with a sloping transom on both Port & starboard sides and a fairly narrow near vertical part leading to a small platform in the centre. I plan to fit the bracket to one of the sloping sides. The flat surface of the platform is taken up with the boarding ladder so no room there. OB is a 2.3HP 4 stroke Yamaha - enough to move the boat for short distances in an emergency.

I have done the same on my Hunter 27 with sugar scoop stern I Got a stainless outboard bracket from a friend that had several holes in it to suit the angle of the transom and is the normal hinge up assisted with springs I was quite surprised that there was already a reinforcing pad fitted to the inside of the transom inside the aft cabin.

Using my 2.8 Avon rover tied alongside is not ideal as when there is no one in it the 4hp Yamaha's weight makes the dinghy's bow rise up and because of the angle of the fore and aft lines it could easily flip over.

Firstly, not sure the outboard will give you much propulsion - and also not convinced diesels are that unreliable that you need a back up! You already have sails as a prime source of power and a diesel as a secondary. A 2.3hp will only give enough maybe to manoeuver in flat water and, assuming it is a short shaft motor from your tender will be so far down as to be almost inaccessible. Towing alongside with a dinghy and outboard is much more effective as you have both steering and motion.

If you are going to mount a bracket on the sloping transom then the normal way would be to have a shaped hardwood block to bring the swingdown bracket into the vertical position when in use.

To me, though, that would be spoiling an elegant shape with something that is of little practical use!

Nigel - thanks for the pic - I have seen this arrangement before but its probably a bit OTT for what I am thinking of and anyway I assume its a Dehler set-up - thanks anyway.

Tranona - I appreciate all your comments and to a large extent I absolutely agree and yes I have considered the hardwood block option but just wondered if there was anything else out there. As far as I am concerned, its a sailing boat, so sail it!! Its just that I found myself in an awkward spot when sailing shorthanded a couple of years ago with the OB on the pushpit & dinghy stowed when the inboard failed, in very light winds with a 5 knot spring a tide taking me towards some pretty big rocks!!. The sail barely allowed me to hold position off the rocks until a passing boat very kindly towed me away from danger and then back to the marina where the engine was fixed. It would have been nice to have just dropped the OB to get me out of immediate danger. Hasen't happened since and I sincerely hope it never does again.

Sheerline - no wind-up. With the OB on the dinghy and the dinghy tied alongside, it will move the boat slowly just fine in flat water - enough to get out of danger but time consuming to set up. If there was wind I would not be on the engine anyway!! I just wanted to see if there was an easier & quicker solution.

I think it's a perfectly reasonable thing to consider. After copping a rope round my prop in St Vaast harbour last year (flat calm too) I'm making just such a thing. 2.3hp would have enabled me to manoeuver into a berth safely, if slowly. It will be a simple ply bracket that will fit into the base of the folded boarding ladder. It won't need to be particularly robust and I won't use marine ply. It'll spend most of its life dismantled in a locker.

In that situation you would have been wasting time and effort with a 2.3hp engine on the back end. The prop would be like a cavitating egg-whisk with little or no effect.
