I just bought a tri-axle trailer for my 25' O'Day shoal keel and I need the critical measurement of end of shoal keel to the bottom of the hull. The only measurement I have ever seen is from the keel tip to the waterline and that will not do me any good. I need to know how high the bunks on my new trailer need to be to clear the bottom of my trailer. Also, if anyone in Northern Calif has a 25' on the hard that I can come and measure myself.... that would work also. Thanks in advance. ken in sacramento
