Re: [Amel Yacht Owners] Weight distributuion

Thanks for your input and opinion. It seems that most of the Amels that I have seen to date seem to be down by the stern at least some but on the other hand I don’t hear many complaints about handling or performance. Perhaps as you allude the Amel hull is not too sensitive to fore/aft trim changing those parameters? That would certainly be a desirable trait to have on a cruising hull but not something that I have studied or thought about much so far... You make a good point about the shallow bows of some boats being must more sensitive to fore/aft trim changes than the deeper Amel bow. The (by todays standards) relatively sharp and deep bow entry of the Amel is one of the things that I really like about the hull design as it seems to eliminate much of the pounding as compared to a more flatish entry.
I like the way my boat handles the way she is (very slightly down by the stern) and want to do my best to not mess that up by altering the weight distribution and changing the fore/aft trim of the boat in an unfavourable direction. My testing in light conditions with no sail up shows that the boat has only a very slight tendency for the bow to blow off which to me means that the boat will be under control at low speeds while maneuvering and so far that is how it has worked out. The bow also does not blow off after a slow tack as many other boats I have sailed do which is important in the event that I am ever forced to tack in a critical area, perhaps with no engine as a backup. I found that while coasting along with no sail up I could continue to turn the boat towards the eye of the wind down to about 1/10 of a knot of boat speed in light air conditions. I feel that this type of balance is really nice in gusty conditions since the boat tends to not be directionally affected much by the gusts giving me one less thing to worry about. Depressing the stern further would increase windage forward and reduce it aft while also moving the CLR aft, all of which will combine to increase the tendency for the bow to blow off at low speeds, hence my concern. On the other hand the windage of an arch would be a little like having some mizzen out and tend to hold the bow up an might compensate for some or even all of the fore/aft trim change due to adding the arch. I guess one could try to work some of this out mathematically but sometimes the only way to know for sure is to make the actual change and live with it. So this is why I am trying to gather as much information as I can before committing to a particular arch design, thanks for your contribution even it if is just speculation.
