Is the GANGWAY good enough to HOIST a Dink ?

[TheThunderbird]

Hi everyone there.

Having upgraded to a decent dinghy (90kg, 3,5m) l find it necessary to hoist it for protecting from barnacles as well as an anti-theft measure.

Hoisting it with a halyard implies disassembling the o/b engine....
I have no davits, nor do l want any.
A solid crane l have astern could possibly work as an additional retention line, but l think that the stress would be close to its weight limit, when operated alone, and not ideally placed indeed.

So, l thought that having a pair of blocks hanging on the gangway outer tip could make for it, embracing the dink with two lines possibly kept at a distance on a titanium rod (3'long).

As obvious as it seems, and safe (the gangway being kept with a dedicated halyard) l never saw anyone doing anything alike.... So, am l possibly wrong about it all?

Thanks

Without seeing your gangway and understanding how it is constructed it is hard to answer. (Actually it is easy to answer, but hard to answer RIGHT!)

But... I wonder why you feel lifting with the halyard requires removal of the OB? We routinely lift our dinghy while at anchor with the halyard until it is out of the water, and resting against the toerail. The engine stays on happily, and all is safe, secure, and dry. It is best to have the dinghy bow facing aft to keep a sudden strong wind from lifting it.

On the other hand our dinghy is half the weight of yours, so maybe that's a consideration?

Pics of your gangway?

We also routinely hoist the dinghy with a halyard and the outboard mounted.

Perhaps the OP is set on hoisting the dink vertically, putting a line on the bow and just lifting it. That could be problematic. Using a proper lifting bridle with at least three points (each side of the transom plus the bow) going to one lifting ring would solve that.

But carrying a dink on the hip generally only works for ships. To add extensions (got any spare titanium around?) and lift it on the gangway sounds like eventually the kludge will break and the engine be lost, unless the OP winds up putting, well, davits on the gangway. Or the stern, and be done with it.

Kudos for acknowledging the difference! Amazing how often -- especially on the internet -- people are quick to offer an answer, without seeming to care whether it is the RIGHT answer or not.

Well, the gangway is solid Alu on a pivot.

As compared to hoisting the dinghy amidship, my solution has some advantages...

Any line works vertically
The dinghy does not touch the hull !
The dinghy is partly protected astern, and offers much less windage (indeed, it is great to turn it backwards, as proposed)

But , in the ordinary airship position, l find it difficult to imagine the dinghy being lifted horizontally when bumping into the hull, (with a halyard some 20degrees out of its line) as it should tilt inward (against the boat) at ease.
Maybe a 2nd person is needed, for doing this...

If properly implemented (no kledge!) l don't see many disadvantages in my idea, yet.

PS l assume a gangway as designed to wear the dynamic stress of a walking person.... So...what's the concern about it?

Here, in the despicable city of catania (Sicily) I find 7/8" titanium pipes at 11eur/meter

Do any of those admitted advantages make any accommodation for hoisting the outboard engine? If not, and you want to keep the engine attached, it is still problematic.

Here in the US, any grade of structural titanium pipe will run $100++ per meter. I have no idea how well the thin-wall stuff supports side loads, but note that a lot of it is sold to handle corrosive solutions, not always structural loads. You might want to make sure that yours can.
