Hi there BC23,
The BRe also tapers in towards the stern; I would think most similar boats do?
I have mounted the floatem poles as far aft on the trailer as I could manage. It appears to me that once the wider mid-body is centralised, the rest goes OK? Meaning the boat seems to be reasonably centralised, while still afloat.
The aft extremity of the boat does not encounter the floatem poles, until after the broadest part of the mid body has already become centralised, hopefully with most load being taken by the keel rollers.
Added, for clarity, I hope...
When the bow is snug against the stop post, the floatem poles are still well forward of the aft cleats. This due to overhang on the trailer (a standard Swallow trailer, but with added keel roller f'ord, and floatem poles). Therefore, the taper of the breadth of the stern is not an issue as far as floatem poles go.
I have recovered in strong cross winds, but my limited variation in sailing locations means I have managed to generally avoid strong cross tide/current.
One thing I still tend to forget, is to put all the fenders inside the boat, once "started" onto the trailer!
Floatem poles mean that recovery impossible with fenders out... obviously!
However, the above said, I have no experience of a BC 23; their owners will be best placed to advise.
A problem I am still having, is that one set (the right hand set, looking forward, from aft end of trailer) of aft wobble rollers seem to always interfere with the stbd side self bailer. I've tried measuring up, adjustments of various kinds and can't find a way to get it so that boat is supported evenly, centrally, remaining level P/S - and with both of the two self bailers clear of the wobble rollers.
Frustrating!
