I have one of your Ultra 10 series 2 ,serial no flt120711049 fitted to a Windy Ghibli 28. After her 1st season she came out for a scrub having been in the water from Easter to September, I could not believe how little fouling there was on the hull, only a few barnacles at the very front of the boat forward of the bow thruster.
To put things in perspective the out drives were unrecognisable under a carpet of weed etc. Please hurry up and design something for them. The yard staff were also amazed at the cleanliness of the hull and to be fair the whole pressure washing of the whole boat including drives and tabs took no more than 10 minutes to completely clean back as original.
I will send you some pictures to show before the pressure washer got to work.
Thank you for a great product!
