Transome height Help!

Hi all
One question Have a 7.8 Ballistic with twin 225 optimax on the back. The transom has been raised to 25 inches already but because of the weight when the boat is stationary it is sitting with only 4 inches of clearance to the top of the transom. I want this boat to go onto a pontoon berth in Salcombe and have the problem that any kind of a swell (even with the stern to the pontoon) is going over the transom. Any one got any ideas maybe a skirt, or a large fender under the engines or some kind of cover. Anyway HELP please.

Thanks

there is a 7.8 balistic in Dun Laoghaire with a 250 ficht on the back, I notice when he Ties up the boat the tilts the motor all the way up, the engine is nearly horizontal at that stage and this might help with by moving the motor weight into the boat.

does the boat take in water over the stern when tied up????

I don't suppose putting some weight (two large, full, fuel tanks?) right at the bow would help, would it?

Weight

Good idean Brian

Fill 2 large tanks with fuel and put them in the bow. That should raise the transom a couple of inches etc. You can buy a transom guard which stops waves coming over the back. Sound like its too heavy at the back.

Yes that is certainly worth a try, even if I just have a drum of water that i leave on the pontoon. The boat is fine when it is running and is well balanced it is simply the chop that you can get running down the bag in Salcombe. Does anyone know much about wave gards and how they work / fitted. I was thinking about mabyt some rubber that clips to the outside of the transome and runns up in front of the engens verticaly. Any idears.

Guards

The guards are designed to stop the wake rushing over the transom when stopping. I'm not sure if they would solve all of your proble especialy if you have twin blocks. Think the drum of water would be best. If you could get a guard it would have to be a tight fit between the engines other wise water would rush in over the gap.

Hi Folks

I saw an artical in RIB International about a rescue RIB where they had built a false tramson inboard of the real transom to stop the swamping problem.
As long as the inboard transon is higher then the outboard transom it should never get swamped.

Regards Gary

Yes I think I will give building an internal transom a go. If it had a hypolon sheet that was weighted then it could have a flap that folds over the propper transom to make it water tight. Prob best to build this out of a thin plastic board I would guess. Appriciate the ideas. Has anyone else got an oppinion or any idears thanks

What about floating the transom higher. Is it possible to have a large fender that i trim the engiens down on to raise the stearn up out of the water, any views on this.

Dave,

There is a hydro hoist going cheap in Jersey if you have access to electric on the pontoon, you can then lift the boat totally out the water!! Also, reduces the amount of cleaning you will have to do!

Cheers
Karl
