And by having a lesser weight up front you would have an advantage in a following sea.
We need more weight in our bow as our Yam 200HP will not trim far enough down, and it needs a little more (not by much). This is because the angle of the transom is not enough for our Yam 200. The boat was designed for a Merc which trim down more than a Yam. However triming it down makes head on solent chop more easy to deal with which is why we have a 50lbs weight in our bow. Another option is to install a wedge to help force the nose down or trim tabs. We dont think we need go that far and the boat works well now.
However that weight does not effect our chinewalking. As I said in an earlier post we get walking when we are trimmed up too high trying to get the fastest from the boat. We get to the point where there is very little hull touching the water and then walking starts. I can minimise it by not reacting to it when it occurs and trying not to swing on the wheel ... I keep it very steady and balanced.
If it walks, trimming down a little solves it and we loose a few mph. However we certainly are not trimmed down as far as the engine will go ..... and so I dont think having weight to hold the nose down is helping much, as there is plenty of trim still available to force the nose down without the weight.
I would be happy to take a look at your boat. We are out Sunday travelling from Portsmouth to Swanage for some diving. Happy to meet you on the way for a quick look, but we will be passing southampton water early! Like 8:30am
