Backing up (or not)
I have been sailing a Bristol 32 (with the board up) this summer so far.
I find that it's behavior is reverse is very sluggish and unpredictable.
I noticed a comment in a Vigor book that the Cape Dory was sluggish and unpredictable in reverse. I noticed that the underwater profile of both boats is practically identical.
The behavior seems to be related to four things:
1. Very low power in reverse even with a three blade prop.
2. Barn door rudder so when the rudder bites in reverse it is significant.
3. The cut-away fore-foot keel seems to over-whelm any other forces like prop-walk or astern propulsion.
The end result is a boat where it is hard to predict its behavior in reverse.
So I have two questions for those in the know.
1. Other than just practicing a lot any tips on backing up this boat?
2. Will every boat that has this same or similar keel shape behave similarly?
The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.
