Re: RRD bar with Airush kite

I have an RRD 4 line bar from, I think 2012 or 2013. I'm thinking of buying an Airush Ultra, and would like to know if i will be able to use it, instead of buying a new bar. Should work fine, I suppose. I have an ozone bar that I am using with Airush, RRD and Gaastra kites, no problem. Some company...

Re: Alaia Repairs

My Naish Alaia glass is worn to the mat in places (dark blue arrow examples) and corners are chipped out (light blue arrows). I made a foam pipe wrap (wrapped in tape) protector to prevent future transport corners/edges/tip damage (bottom picture). Looking for tips on what to use to fill & seal the...

Re: Stupid beginner question - waves in your face?

Wearing a vest with some buoyancy (e.g. impact vest) helps, the head gets less time under water.

Re: Dying after board start

Make sure your kite is big enough for the wind you are kiting in. If you are using a kite too small, it is very hard to get it up to speed. Also I know some learners who have benefited from this waterstart technique: when putting your board on keep your kite low (like 10 o'clock), then start by quic...

Re: Building HF-board; as light as possible, what construction?

I am in the process of making a board of similar dimensions (125x46cm) but mine is thicker(4.5cm). Made it from XPS foam, the bottom has 200g carbon and 110g glass, a bit more around the foil box, the top has 200g carbon + 110g glass plus the deck area has additional 200g carbon plus the foil box ar...

Re: Bomb proof board from XPs insulation foam

The board weighs in currently (with a fill coat on the bottom weave and rails) 1.8 kg I now need to glass the top with rail wraps down to bottom curve. Am thinking of 2x 6onz with a 4onz patch over mast mount. I feel that I have perhaps over built it but it is the first time I have used this foam a...

Re: Bomb proof board from XPs insulation foam

Woodie Cookie in the Netherlands, an ex-raceboard champ, board designer and now foil designer, has made some hollow raceboards. Can anyone think of a good reason why hollow boards wouldn't work for foils? Hollow boards do work for foils, I know that a local company Stradi Custom Boards built a batc...

Re: Bomb proof board from XPs insulation foam

Last winter I built my bombproof foilboard using the xps core (2 cm thick) and 3mm plywood on both sides plus wooden reinforcements inside. Works fine but is quite heavy.
