Is there a Clear substitute for antifoul ?

Hello resently i brought a tige 22v rider edition which im partictally please with but i live on the south coast of the UK and saltwater is my only option.The boat is going to be kept at a marina for 6 months of the year.Now heres the problem the whole hull is lime green (trust me it looks better than it sounds) and some kind of antifoul is going to be needed but they dont make a green antifoul even close to lime green.the thought of painting it in a grey or white antifoul would really spoil the look of the boat.So does anyone now of a clear antifoul or a clear substitue that actually works ? Ive heard of a wax which they use on the rubber of ribs but its VERY expensive and i dont know if it actually works.Please give me any knowledge you have and where i could get anything that could do the job.Thanks for youre help.Happy boarding.
