Building an speedneedle foilboard/windsurfboard in one DIY!!!
Is it possible to build after so many years of windsurfing something new?

You are a genius and an inspiration. Glad I'm not the only one who cuts the nose off a board if it won't fit in the van!

[@disorderart4507]

haha I'm about to do the same :D chop the nose on old long wave board to make it look cooler. and this dude is the master!! skills and techniques he got are brilliant.

[@franciswhite1690]

Muy bueno

[@windsurf-tn4ro]

well worked and you have good music taste too! MSG :)

[@jaryH3]

Normally I don't like music on the videos, but when watching this, I didn't know what to focus more on. Music great, work you did: great, got inspired : check, instant subscribe: done!

[@tomg.542]

Exhausted just watching this! Jeez how many hours were spent on this project? And It's a good illustration of how labor intense board making is, and why even when built in the third world they end up costing thousands of dollars.

I campare u with Da Vinci, butMost of the Da Vinci´s work is Just concept But u Go beyond. U go from concept to development , manufecturing and texting it and that is Amazing!! I thank u a lot for sharing that with us...

[@paoloprotti2032]

Grande, Bravo!

I built a boat with a planing plank on the bottom like that once. Was amazingly fast with a small hp outboard and very stable at rest.

[@robertcain3426]

Does it work - increase speed? If so, why aren't the speed record boards designed this way? Also I don't think you need the extra carbon over that addition as carbon is for stiffness and not strength and there is already enough stiffness in the original board let alone adding another. E glass would be a better option.

[@johnrflinn]

Carbon fiber is worse than asbestos for your lungs and skin since the fibers are so thin and strong. It's a very good idea to use protective clothing, filter, and googles when working with it.

[@wimvanthof4039]

Bekend boardje! 😀 Mooi om te zien!

[@robrockwindsurfboards75]

Moest er even over nadenken, maar het is inderdaad een voor jou niet vreemd boardje.

[@tomkole7634]

Hey Rob, it's interesting that I made 3D model already in Jan. 2015. The same idea!!!

[@petergalli2001]

ARTE !!

[@chrisdyer6370]

Simpler to glass carbon directly onto the polystyrene with an abundance of resin, dry second layer of glass on top soaks up the excess resin when rolled down for a fully wetted yet dry laminate. I regularly shape surfboards from polystyrene.

[@leanmachttv]

awesome

[@darealmietz]

Hey Rob, genius idea and awesome work! You encouraged us to convert an old mistral energizer to a foil board... I will share pictures ASAP. we finished the connection for the (kite-)foil yesterday and tested it today. It started to foil pretty easy but then always rolled over to the lee side. On an extreme downwind course we could foil for a few seconds but then got too fast, turned upwind and crashed ... It feels like the board is too narrow to get enough pressure on the luv side, but I have to say that we are absolutely new to Foilsurfing so it could also be just our lack of skill :-) we read that the width of a foil board should be at least 70cm so our next step will be to make it wider... Problem is that the Board is 59 cm at the widest point 🤔... At the moment our ideas are to make it like outrigger like some boats (I.e moths) have... to leave the bottom like it is and laminate a wider foambord on the top/deck with a little v-shape... it will look definitely funny... do you have any experiences, ideas or recommendations for us?

[@robrockwindsurfboards75]

Maybe at first glance and not a simple solution, but worth considering. Cut the board twice lengthwise. Saw something of 6 cm left and right of the mast track / tuttle box and then glue (2x) 10 cm thick EPS between them. The total width then becomes 79 cm. A little shaping / laminating / painting ..... done. Foiling should then become a lot easier. Have fun with your DIY project.

[@darealmietz]

Hi again, and thanks for your idea. I haven't mentioned, that we don't have many tools and much space to work with :-) You'll see in the pictures and lough out loudly... so unfortunately we will not be able to cut two straight and parallel lines through the whole board. We'll widen the tail to the max. width as a first step and flat out the deck to get a more upright stance. If this won't help we'll follow your idea and make it even wider. And if that won't help we'll build a completely new board like you showed in the other tutorial :-)

[@FranciscoRodriguezCasal]

Hi! Great job! As always! I have one question : what did you use to close the pinholes? BR

[@gh0strid3r92]

looking nice, but i'm more into that carbon look ;-)

[@jaaaake777]

It looks like the planing plank on this is about 25-30 mm deep. The shots of it underway show that even at full planing speed the upper board still has a lot of influence re: skin friction. So have you looked at making the needle board thicker? Can you get away with making it thicker than you have or would that render it unsailable?

[@jkkoolen]

je zou spanbanden kunnen gebruiken om de spanning erop te zetten in plaats van die stenen

[@fertysurfer]

Hi Rob. What is the drying time on your resin? You seem to have hours to work it.

[@zincopper]

Nice job! Can I buy it off you?

[@VirtuellJo]

A few minutes into the video the music changes and I am thinking that I have a Nice playlist going, then I realize it is only demo video I ever have seen with proper music.

[@mohamedfgaier967]

i love your channel what news have you?? new DIY ??

[@woodyadal962]

Skis and Snowboards changed from parallel edges to parabolic edges. Would this work for a windsurfing board (non-foil board).

[@Movecam]

Hey Rob, wat voor materiaal is dat gele schuim dat je voor de sandwich gebruikt? ( en waar te koop?)

[@Ustrajni]

As always, a nice job. What is the height of new styro + sandwich? It looks about >3 cm. You gave me an idea about my old F2 Xantos, but I would rather put up to 2 cm. Any advice, considering your experience?

[@robrockwindsurfboards75]

This board has an "extra" height of 4,5 cm and is 27,5 cm wide.

[@Ustrajni]

Thank you.@@robrockwindsurfboards75

how to repair a deck that had come loose or broken

[@carmineminardi5210]

Hi, I'm thinking about how to repaint the down part of an old board. Many people told me to use car paint ( bi-component) because it's harder, I'd like to know if it's possible to brush paint the bottom of the board and than dine sand it till reach a mate and flat finish ( no sing of rollers or brush). Is there anybody out there that can help me ?

[@XSAILOR65]

What if You would have left the stern part of the "plank" straighter? probably more drag at lower speeds but when properly planning, less drag, acting like a planning hull?

[@XSAILOR65]

Actually looking at the video the water flow at the stern looks very much as from any planning hull already now:)

[@13jshark]

...Urithane glue with EPS? How?

[@vespa2901]

Hey Rob, nice work. I saw this type of board just a few days ago, I think it was a fanatic prototype. But the rider wasn't satasfied. Well he used it with a foil. I think a foil on that type of board is nonsense. Because when the board is liftet there is no contact anymore. And before lifting, that shape doesn't plan as good as a regular flat shape. But how does it work for regular fins? What advantages this kind of shapes bring? Does it really just plane on the small bottom? Is the planing ability still exactable? Is it turntable while planning? I could imagine it goes straight like on rails. Thx alot

[@robrockwindsurfboards75]

What a questions ???? The video you mean is from Nico Pico. I received seven reports from surf friends that my idea was stolen. Ha Ha. The first reaction under his video is from me asking why the board is not good. (read it yourself) The deck has a huge concave and is difficult to control when jibbing! (And in my opinion this board should not have cut outs.) ? Plans this board later; NO. ? I think a foil on that type of board is nonsense. ; The advantage is that when foiling with a hard landing, the smack is absorbed more gradually. ?Does it work for regular fins. ;Yes, the fin can be smaller. I use no longer than 32 cm. ?What advantages this kind of shapes bring. ;You only need 1 board! Low wind foil - lots of wind fin. ?Does it really just plane on the small bottom? Is the planing ability still exactable? Is it turntable while planning? I could imagine it goes straight like on rails. : The board surfs just like any other board. The acceleration is much better. More control with a lot of wind. Only jibbing is more difficult.

[@woodyadal962]

@@robrockwindsurfboards75 For a windfoil hybrid is there a board tail design that would allow for better foil pumping vs a sail pump?

[@willgraham8124]

@@woodyadal962 I believe the idea for the JP board was that increasing the volume in the tail increases the pumpability of the board. However in that case, the step was so big that it actually made the pumping action harder. Personally I don't think cut outs in the tail would help earlier flight. As the cut outs are there to reduce drag once the board is planning. By with point you'd be flying on the foil anyway. I think starboard probably have the best foil board design currently.

[@christianpama4943]

super Idee!

[@mrimpepe]

Im still waiting bro! Where is teste ruun!??!

[@robrockwindsurfboards75]

Its online now.

[@mrimpepe]

@@robrockwindsurfboards75 just got initiated to windsurf because of you mate! And got some inspiration to try to make a board. Starting with a standup, so dont need to put some mastrail/fins etc. Thx for the content bro! Tamo junto!

[@Beachbumextraordinaire]

You do realise that you managed to succeed in a design which jp failed in :)

[@mark051262]

Mert Ozener to be fair, the failed JP board was a foil board, not a regular windsurf board

[@Beachbumextraordinaire]

mark051262, correct me if I am wrong, but the shortcoming in JP’s attempt stemmed from this “ridged” rocker design was its inability to plane easily, something that is presumably an asset in foiling, just as it is in regular windsurfing. In this respect, Rob Rock seems to have pulled it off. Moreover, his new board is also foil proof.
