Combining the 2 incoming 220v cable into one

[Crystal TLV]

This will be much more convinence for me as the Y connection on the incomming cable maks a lot of trabbel.

Is it ok to combine the 2 waires on the boat to one plug only?

DO NOT DO THIS.
At the shore end there is a protective device (breaker) at each outlet and paralleling up two supplies will result in improper protection to you.

Under no conditions should you do this

My friend,
There are very straight forward methods of connecting shore power to boats.
If you use anything other than ABYC approved wiring connections, you risk electrocution.
Rule of thumb on a boat. Unless you really know what you're doing, don't mess with the shore power wiring.
I can't stress this enough.
Speaking of which, I want to point out a safety tip that I want everyone to follow. 100% of the time. Not 99%

Whenever you are either:
Leaning over your engine
Working in a cockpit locker
Accessing anything where you are up to your elbows

Unplug your shore power !!!!

At our club many years ago, a guy was working on his engine.
Real sweaty, and his chest was draped over the engine block.
When he straightened up, his neck touched a live 120 wire.
Lights out.

You never know if a previous owner ran a wire somewhere, or if an installer made a mistake. Never take a chance. Unplug your boat.
If you have an inverter, make sure its off. It will electrocute you the same as shore power. If need be, turn off your battery switch.

Improperly wired shore power on your boat can potentially kill a nearby swimmer in the water, and cause your and your neighbors zincs to corrode rapidly.

In case the risk to yourself wasn't a good enough reason not to do this...

Thank you but it is not answering my case. the shore power is only one cabel! [there is no option to get anather one] for years the one shore cable splits right befor the conecting the boat into 2 cables in a simple Y connection.
what I want to do is to get red of this Y problematic connection and use one connector with one plag and make the inner cabels be from one sorce from the one plug.

Hire an electrician,
Nobody on this forum is going to advise you on how to rewire your shore power.
Way too dangerous

Is your boat wired internally to US standards or EU standards? You are in Israel so I suspect you are running 220V internal to the boat?

At least one simple solution....

If understand your situation, you have one shore plug-in. Your cable has one plug that fits into the shore power receptacle and it splits in a Y into two cables close to the boat, both of which attach to your boat. I also have a 356 and if yours is like mine there are two separate connectors on the port side of the stern. Each of those connectors leads to a separate breaker switch in the port cockpit seat locker. In my boat the wires from the two connectors lead to separate branches (A and B) on the AC electrical panel, and there is a selector switch to use one, the other, or to parallel both for all electrical loads. If that is also the case in your boat, then you can replace the two cables of the Y with a single cable, connect it to either of the boat-side connectors that lead to the electrical panel's paralleling switch, and have no problems. You just have to choose the proper position on the control panel switch, which is easy--nothing will work if the selected branch (A or B) is the wrong one. But keep in mind that since all the boat's power has then to be supplied through one breaker switch the total current that you will be able to draw will be limited the capacity of that breaker. Since you apparently have 220V, if the breakers are designed for 30 Amps then you should have the capability to run everything on the boat as you do now. However if the breakers are designed for 15 amps then you may not be able to have all the equipment on at the same time as you would if you used the Y on the shore power cable and kept the panel switch in the "parallel" position. Remember that the capacity of the breakers is designed to protect the boat's wiring from overheating or fire by limiting the current that they carry.

However, if you have a different control panel that does not have the capability of choosing or paralleling the two wires from the the two connectors then you may not be able to do without the "Y" without losing the ability to power some electrical equipment. If you will describe your arrangement I may be able to suggest changes to make it work, but any such suggestions should be checked with someone local to you who is skilled in electrical matters to actually do the work.
