Title: M15 & the Easter Bumps - First downwind of the season
Post by: burchas on April 22, 2019, 03:47:14 PM
First downwind run for the season and first run with my new downwind prototype.
Quartering tail wind, we had to surf to the right for 11 miles. Had a blast

Yes. Nothing beats a low volume board. But,but....it should have been orange and grey :-)

Nice downwind run. The wind was really ripping. Angry looking waves too. BTW, that is an excellent looking downwind board. Love the broadside shot of it.

Thank for sharing the video.

Very nice indeed. Low volume, plenty of rocker and a big blow = downwind heaven.

Wait, what? The season? I didn't know there was a season. No one tells me anything.

Looks fast and surfy! Yuval, what are those two black dots on the side? Graphics or?

Thanks Guys!

Bill, there are no seasons for seasoned chaps like your self.

Greg, those dots are threads for mounting grab handles.

Eastbound,  :) :) :) Thin is in :) :) :)

Side grab handles. Yes. That is a nice touch that could benefit so much the Naish Maliko....

Easy enough to install. The hardware is $20 including the handles. You could probably make
it your home project and do it your self now that you modified your paddle ;)

I applaud your confidence in my skills but likely not :-) If it would not take two months to get any sup repaired here, I would have it done. the handle on the Maliko simply sucks and is not really safe fro down-winding use.

Yes. Nothing beats the SIC style handle which I also included with this board along with deck loops for paddle portage. All very handy in these conditions.

Was this your design? Very curious about how the thin rails worked, say in comparison to the polka dot F16 that was on that trip with the traditional SIC thick rails. I would think that the thin rails would be much less stable, but much easier to surf. I am unclear about what the effect would be on speed and glides. Anxious to hear about any comparisons.

My custom UL downwind boards are also very thin, with lots of rocker. I think they are only about 4.5” thick.

They are actually MORE stable for their width than the thick SIC downwind boards I have. Lowering your standing position makes a big difference, as does not having big fat rails which can catch every bit of chop and wind.

One way to look at this is that everything *in* the water keeps you stable, but everything *out* of the water is excess that will make it feel more like you are standing on a log getting blown and pushed around.

The lower volume boards are however slower than thicker board when they are not planing. You will get more water splashing into the deck around your feet, and the thin rail shape will mean that the rails are biting the water more. This makes them slow in flat water. But the bite of the rails also means that the board is much easier to control, more predictable in its handling, and surfs MUCH better. Plus, steering on a wave does not require a rudder. This combination of handling characteristics makes the low volume downwind board to be much more FUN to ride, especially in high winds (over 25 knots; preferably over 30).

So, if you only care about average speed, and you are willing to put up with a less stable, worse-handling board in order to get that extra 0.5% of speed, then get a thick-railed downwind board. But if you want to surf your board on the bumps rather than pilot the board, and your aim is fun, stability, and ease of handling, then get a low volume board. Plus, for many of us who aren’t pros, the extra handling of the low volume board will actually translate to faster speeds in practice: you can’t be fast downwind if you are teetering all over the place.

Yes and many of the design choices I made align with Area 10's comments. A lot of it is dictated by conditions the board is intended for.
The F16 in question is the hollow V3. If I remember correctly, you have the V2?

I took a different approach with this board to try and mitigate some of the shortcomings A10 described. Even-though the board is only 15'
It has more waterline than the F16 due to much relaxed rocker. 2.6" Tail and 8" nose.

As for bottom I went with what I believe to be simple and fast - Flat through most of the shape with a very rounded V towards the tail.
Very predictable and smooth handling. Also moved the wide point of the board a lot forward to shift more volume and surface area
near the entry rocker which I believe promotes early planing and stability.

The result is a very surfy ride, board maneuvers on a thought, you can carve it easily and never have to worry about rudder drag or malfunction.
15' means better fit into shorter period bumps, I don't remember going on the fin even once during the ride and my fin is 2 fit from the tail.
Glide seems to carry well so I didn't have to work hard for connections.

So in comparison to F16, it feels less draggy on flat much more nimble and maneuverable anywhere you stand, surfs better and just as stable.
You have to move on it more but you don't have to move much to trim well. It's going to be much better ride if the wind has a lot of side in it.

It is still too early to give a good review as I need many more runs in the various conditions we get here, but I'm stoked.

Nice skirt dOOd!

Looks like a fun board too by the way.

I forgot the cape at home that day :D It sure is a carver, just how you like them.

Fin? Could not recognise the fin on the last frames. Looks longer than a GTS.

You're right. That's a new template. 8.5" long, 7.5" base. Not sure these are final. No name yet.
