Alongside pontoon berthing

I have recently taken an alongside pontoon berth and I am wondering if where I have been placed is a good spot and whether to request a move to another berth as and when one comes available. The pontoon is new with only half the berths occupied but all have been allocated now so the place is notioanally full. My concern is that the boat in front of me ( not there yet) is a 10m cat and my cat is 9m overall. The beam of the cat in front means that I will need to approach the pontoon at a steeper angle than if it were a monohull in front. A consequence of the steeper angle of approach perhaps 75 degrees to the pontoon is that due to my relatively wide beam my starboard rear quarter will get close to the boat behind. It obviously depends on the spacing between the boats whether I have difficulty or not but it is a concern as I only have a single outboard so berthing can occasionaly be a challenge.
I am probably worrying uneccesarily but I am not sure putting cats together is a good idea? I will know better when all the boats are in their berths and set up.
I am not aware how marinas set out their berths and if there is a standard spacing between boats and whether it depends on the size of boats and whether power or sail and normally prevailing tidal flow and weather situation?
I would be pleased to hear any thoughts on my possible problem as I am sure many others have been down this road before.

Cat owner- Sorry but it is your own fault ;)

But on a more serious note with only a 30 ft cat can you rotate the outboard fairly sharply? If so put one bow in at 45 degrees. Then put the out board hard over & use it like a stern thruster. Pushing the stern in with the bow anchored to the pontoon. Adjusting the bow line as necessary so that the bow slides along the pontoon (along a fender of course) & the stern gradually swings to the pontoon.
Obviously other factors- tide, wind & wallies shouting pointless instructions, all have to be considered.

The river where I berth is wide enough for two way flow of boat traffic...but it’s increasingly becoming a cat haven....with cats it’s now a oneway river....ie in whatever the direction the cat feels like going...there is no regard for the rest of the river traffic

Our last berth was just like that. In between 2 ultra wide beam cats. We have outboard steering. Our main difficulty was when the wind was blowing us off. There was often insufficient tide to ferryglide anyway. My advice is to throw dignity to the wind. Put your bow or stern onto the pontoon, take lines ashore and either motor against them or put a bow or stern line in a winch and wind her in.

We have a 29' cat. We do have the unfair advantage of twin engines but, even so, things sometimes get awkward, I usually find it easier to go in astern, get a line on then motor ahead to bring the bow in. Yes, you'll be close to the boat behind, but at least you can see exactly how close from the helm.

The cat in front of me is now on its berth. It is a Broadblue Cat perhaps 18ft beam. The spacing between my bow and his stern is only about 4ft and 7ft from my stern to the bow of the boat behind. This feels very tight apart from the wide beam of the cat in front issue.

We’ve folded our boat before now to let people in or out. Though it’s also possible, good mannered even, for multi owners to take a line from their outboard hull and assist the arrival or departure like that. Ask the owner if you want to leave.

Years ago - entering Bembridge IoW ... a Cat insisted on hoggng the mid channel when you get to the two spits just before harbour opens up ... my Father was already committed in the channel, cat could have easily slowed and let us complete as he was still not actually in the narrows - we were forced over and we spent the day stuck on spit sand.. having run aground avoiding the idiot on the Cat.

and that is why nobody likes cats

I have nothing against Cats ... but they are not for me.

But there are some dumbass owners of boats monohull and multi out there that ought to have some lessons in sharing waters with others.

On Superanne - I was entering Langstone Hbr ... keeping to stbd .... a large Nicholson comes charging out under sail - sheeted hard in ..

Now anyone who knows that entrance - the tidal flow there is serious ... and I'm taking care not to hinder others .... I'm well over and maun channel is clear

The Nich forces me over to the side of channel .. why he had to keep pushing me instead of tacking earlier ?? As he tacked, his mast over at angle - his spreader caught my cap shroud ... the BANG was like a shotgun going off ...
That was enough for me to let loose a string of verbals ...

I was coming up the river to berth…you can’t miss me, I’ve got a fly bridge and a mast almost as tall as a sailboat…especially from the elevated position that the pilot has from a sailing cat…yet he chose to pull out right in front of me…and there is no room to get around each other.
