FPB 64-3 Video #3 – More Play In A Gale
While the Arizona Wildcats were thrashing Duke in basketball, we were out in the remnants of another New Zealand gale with Iron Lady. For company there were eighteen visitors from around the world (three parties of six). It had been blowing from the east for two days, so as you might imagine, the combination of […]
Iron Lady Sea Trial Video #2
While we were busy marveling at how well Iron Lady handled the previously mentioned vigorous sea state, her owner, Pete Rossin, shot a couple of minutes of video.
We picked up the files this morning and you can view the unedited video by clicking here. The quality is amazing and the camera work very steady considering […]
Testing Iron Lady In An Onshore Gale
News awaited that the long spell of pleasant New Zealand weather had finally broken down and strong gale to storm force winds with heavy rain were forecast, exactly what we had asked Circa Marine to arrange. As you can see from the lead photo, these new seas, onshore in angle and so reflected back, were steep and confused. A perfect day for testing.
FPB 112 – Getting Close and What We Fear Most
What we fear most in the design cycle is getting so locked into a single concept that we miss a much better approach. That is why we drag out the preliminary end of the process, to try and make sure we look at all avenues. Although the previous riff on the FPB 112 was good, […]
FPB 64-3 Iron Lady Sea Trial Video #1
We have been studying the motion of FPB64-3, Iron Lady, with an eye on what we are doing with the FPB 112. The difference uphill, between this and the previous 64s which do not have the swim step extension gives us some wonderful data. We shall shortly see how this works for ourselves, but for […]
The Impact Of Scale In Yacht Design
As we work on a new design we frequently refer to past projects. We used to overlay paper plots of lines drawings and compare how volume was handled above and below the waterline. There are the numeric values to review of course, but in the end, when you are talking about how a given shape […]
Exhaust temperature range?
Hi,
We have a Yanmar 4 cylinder turbo charged engine of about 60 hp and would like to know the exhaust temperature range we should target when powering, as distinct from the Vetus cooling water alarm we have available to fit which will trigger at a relatively low temperature?
The boat is a Southerly 135(13.5 metres) of […]
FPB 112 Design Cycle – Working Through The Tradeoffs
Ed Firth, one of Circa’s engineers, has been with us in Arizona the past week, refining the preliminary FPB 112 design. We thought a few comments on the process might be of interest.
As we have discussed before, capsize resistance and recovery are critical components of yachts intended for offshore work. This is a function of […]
