4'4 21L Grubb Pro Wake/Tow
A little extra surface area and volume from the 4’0 18L Brian Grubb Pro Model, same high-performance ride. The 4’4 21L Wake/Tow Board is the big brother to the 4’0 18L, built for bigger riders or those who want a bit more stability.
It shares the same compact, high-performance shape but with extra length and width for easier takeoffs and added control. Whether you’re progressing your skills or looking for a smoother ride, this board delivers — without compromising Grubb-approved performance.

New Favorite Sporting Activity
My best buddy and I had such a great time in our first lesson together with Mark at Luxury Surf. We both stood up and learned all the basics. The headphones made the communications easy so we could focus on improving our skills at riding. I bought my Efoil shortly afterwards and Mark helped there too. Now I have a new favorite sporting activity that is a great workout!

On my first lesson with him I was able to Foilboard right away, fell in love with it and doing my lessons every week now. If you love your life, if you want new experience- don’t think twice and call Luxury Surf to set up your appointment!
