extra handling mods

[haggis]

So i got a rideplate and toploader etc for b1 and will be running them for the first time tomorow :woot:.

But ive been thinking about making some rear sponsons and was looking for feedback, are they worth while? is there a specific shape that might work best?

Also ive been looking at a few pics of mod hulls and see that they are a little longer at the rear, does this reduce porpoising or increase top speed? I thought about building some bolt on hull extensions, any thoughts?

Mod hulls are extended to help with hook up, but also because the pumps have been moved back 3-4 inches. Also, the concaves are deeper and the chines are lower. Basically, a completely different hull. But, works really good.

Extensions on a stock hull do work well. They don't make the ski turn any sharper, but they help keep the nose down in the chop and in the turns. The best way to get a B1 to turn is to get that nose berried in the turns.

Some people have used the TBM SXR sponsons on the back of blasters. I haven't, so can't give any opinion on it.

FYI the key getting a blaster to turn is weighting the outside corner in the turns. Meaning, when making a right turn, your left foot should be pushing HARD on the left outside corner. The more you weight, the better it turns.

That is pretty much exactly what i had in mind! did you make them or buy them?
They must be roughly 3" or so? i was thinking i would make them a good length say 4-5" then trim them after they are fitted to the ideal size.

Are these designed towards surf use or would they be a good addition for improving turning etc?
This ski wont be used in surf very much, its more for ripping around buoys!

My brother made this set. They are exactly 100mm long, as that is the legal limit you can put on the rear and still race. I can tell you, it doesn't take much to get the nose to stay down. After riding stock hulls with these, I don't think you would ever want them any longer. Just my opinion.

no one makes a drop nozzle kit for the Blaster?

Sorry to thread jack but I got a question for you Scottie. I always place my feet like you described but I'm leaning to the inside of the turn. Should I be trying to stand up straighter, or even towards the outside corner to get more weight on the outside rear?

Pro-tec makes drop nozzle kits for B1's. Brian @ Thrust innovations was suppose to be making a bracket to enable his trim system to drop rather then raise for freestyle.

You weight the outsde corner opposite the direction you are turning while at the sametime many of us throw out the opposite knee out over the water and also positioning your upper body over the water. Carves like a pissed off mama on Thanksgiving!!! AKA deep, hard & mean....

I am in the process of Modding a new set of Riva SJ sponsons for my blaster. I want to leave alittle gap between the gunwall and the sponson. I'll run these and see how they carve and hold speed through the corners.

I have ridden other style Blaster sponsons which allow no water to pass between gunwall and the sponson. Sure they hook hard in the corners but while carving it feels as though they loose speed. I notice the drag soon as they hook in.

Shank,

You still lean in, don't shift your weight outside, because you will end up causing the pump to unhook and spin.

Just lean inside until you feel the ski get on its axis, then push hard on the outside edge, the ski will bite. The harder you push, the harder the ski will turn. You can also shim the rear of the ride plate a little, it will put some downforce in the nose, which will also make the ski turn.

sponsons

I made these out of starboard with threaded inserts. Worked great.

Great info guys, i was out yesterday and was pretty pleased with the change in handling, and weighting your outside leg realy does let the hull bite hard and stay hooked up. I havnt figured out yet if its quicker to turn standing or sitting down but either way its awsome fun!!!!

I think i may just make a set of rear sponsons for now and see where they work best before i go with hull extensions. I will also shim the plate a little aswell.

I cant amagine you would get the ski spinning out with them!!!!
