My Thundercat

[roflhat]

Got out for a spin on saturday, didn't want to wait too long. Boat and engine both performing beautifully, the engine seems even better after a good flush out!

Latest idea, have actually been thinking about it for a few years but never looked into it.
Plan is to make an active front wing, positioned in front of the nose cone. Using Arduino board as a controller, gyro/accelerometer as input then servos to adjust the angle of the wing. So during normal running the wing will have 0 angle of attack, may actually improve the airflow over the nose cone. Then if the bow starts to rise too much it will point downwards, to bring the boat back level.
If it all works then I could possibly have the two sections seperate and use them individually to aid cornering



going to try foam wings first then if it works try some carbon fibre ones

Really I'd like to change a few things about the hull design, flatter deck relative to the running surfaces, stepped hulls at the rear to reduce wetted area.

Made up some flaps from an old bodyboard, they're thick but so is the leading edge of the nose cone anyway so shouldn't have much more drag. Just waiting on parts to arriving, need to learn how to program an Arduino board now!

Haven't done much with the thundercat lately, spent 3 months in Arctic Norway again.




Now working with Ineos Britannia towards the Americas Cup as chase boat captain


Going to sell my current thundercat, planning on buying another in white as I'll be based in Palma then Barcelona over the next couple years. Trying again to do some CFD testing, this time of different floor angles in an attempt to improve stability at high speed. All the manufacturers are currently lifting the level of the floor at the nose, which makes the boat far twitchier. Probably ok with 50hp and in the rough but not good for high speed


Also got a new model of propeller out, the Forge V3. 12x22, which is more suited to high speed. Planning on tuning a few for my own boat, they're close to the size of my fastest props

Having a shot at some more CFD myself just now, using free online software but going to see if I can use the software at Mercedes F1, working closely with them

Was down at the thundercat race in Plymouth last month, not taking part but got a zapcat to use for the day thanks to Jeremy Linford.


Back home for a week just now, entered a local rib race on Saturday. The navigation race was 18 miles, got spat out of the boat 5 minutes in. Choppy out there, did a jump we landed and the boat just hooked threw me out. Ian my copilot was hanging in by one ankle, looked pretty sore. Had to swim over and push him back in. Still carried on, tough racing a 10m rib with 500hp and a full suspension cabin. Came third in that challenge then 1st in the two handling sections which gave us 1st overall. Superb day out, don't have any photos just yet.

Today playing in the surf, tried launching from the beach which didn't work. Great fun again though, going to try use the boat as much as possible this week.
Put a deposit down on a zapcat in Palma already for if I ever get out there. But definitely going to buy one for home too, decided I can't be without!
