what about spain? Will spain do? And how to compose a powerful navy? I Saw britain and spain both have around 50 transporter, britain has one fleet with a dozen pure heavies other fleets are frigates, does heavies trumps everything? just buit as many as I can, what's the situation in coastal fighting with regard to heavy fighting galleyI'd say not very likely, but he may try naval invasions if there are no other, closer targets for him to siege down. But even if he does, Ottomans usually roll with gallies, which will get slaughtered by superior English naval quality and his heavies, especially if you are playing with Rule Britannia and he gets +1 to his rolls from the wooden wall.
All in all, if your strategy hinges on the Ottomans going to Britain with their fleet and beating them, I'd say it's not gonna work. You might try to sneak a landing if he gets near and a prolonged naval battle ensues, but don't get your hopes up.
