Since it has winches, can it be considered a sportboat? HTFU and throw on some ratchet blocks!

I think the winches are to wind the keel up into place

So the idea is this scales up 10+ times to be the fastest mono in the world? By that logic you could scale up Custard Truck and be faster...

Yeah but CT won't scale like SD, which is really half a catamaran with an external righting arm.

would love to see this thing in a blow.

looks like on its way to big-boy size SpeedDream could ruffle some feathers in the sportboat camp first... it'd be interesting to see what it can do vs the usual suspects in the powered-up schoolyard corner once it's sorted.

Watched it again and correct myself. obviously sheeting the jib in. so how do they crank the keel over? Like a Mini?

Fucking ugly, seems silly and can't believe Cam is now in on the action. What kind of Moose shit are they smoking up there in Maine? Dang pass that stuff around! I guess Bleeding Edge means snapping a "line"..really? Like the enthusiasm..how is it supposed to go downwind? Looks like it will be sub-surface half of the time.

@ Mr Clean
Not sure I'd describe Custard Truck as 1/2 a cat as it is one of the quickest sportsboats of its size in NZ and a good benchmark to see if this idea of canting lead works on a boat this length.

Given Shaw yacht Design's experience in canters (9m, 10.6m, etc) and the decision to run a small fixed bulb with max righting moment from bodies, I am not entirely sure that the speed dream small size approach is the quickest way to make a sportsboat fast.

Of course...you cannot scale up the crew to each be 5000kg so perhaps speed dreams' appoach is spot on for a big keel boat though.

interesting stepped hull and planing surfaces, hope it works well, with a swiss boat, aussie, and now russo-american teams exploring the dry bulb concept, all that is required is for someone to build Humphrey's deck level sliding ballast and we should see at least one prove out.

Yeah looks very like cat sailing instaed of lifting a hull they lift a keel out of the water :P

Great times, mono's lifting the keel out of the water to imitate cats, cats lifting the whole platform out of the water to imitate birds, and kite surfers abandoning the mast, and hulls standing on foils alone :D

My snide point is that Vlad Mournikov comes up with some great high tech concepts from time to time on how to design the world's fastest mega monster monohull, it generally comes to naught because people quickly realize that a far more cost effective way build the fastest boats for RTW record breaking is build one with more than one hull. You can put all the CFD and other high tech engineering into it you want all you'll end up with is records with qualifying adjectives.

AFAIK the sb version is is only meant to be a proof of concept so I wouldn't expect it to be competitive on a real race course vs other boats that use more sensible approaches to generating righting moment (e.g hanging 4 fit dudes off a trapeze) and hull shapes more suitable to a boat that size.

I am waiting for Vlad Mx-Ray follow up with interest (I'm not saying that ironically) though as it should be interesting.

Has anyone seen any speed numbers yet? Has the boat gone up against anything else yet? Lot's of pretty pictures,, big presentation at TedX but no hard data.. hmmmmm

they gotta be getting some GPS tracks. Christ, I get them even if I go for a quick windsurf session.

Seems draggy when the bulb is in the water.


I love seeing new concepts being tested though. Keep at it guys! The first year I had my F24, I broke something every time I went out. Not as much drama now.

Um,
He was describing Speed dream. Not CT.

regarding the post a few days ago.

I can't help but think the first thing to happen on this overcooked slab-floored wedge is it will stick straight into the back of a roller, nosedive, stop, the weight to windward will screw the boat violently to leeward, chinese gybe and it will all finish in a floppy mess with the rig in the water and the keel returning to its natural state - pointing vertically downward, whether still attached to the hull or not.
 
Vlad needs to sail a skiff for a few years ;)
