Re: OB15 questions by email

More questions from Roman: I was busy the last days. Thanks for the Answer. I found the sheets with the full size patterns. The sheet with transom and molds are easy to understand. The sheet with the pannels is not. I understand, that the different lines represent the Bottom and Sidepannel. But i ca...

Re: LB26 Questions

Strut questions: 2. For the machinery it looks like my prop shop is still having a challenge with the strut. Can you provide/confirm: a) What is the degree of the the stern/trailing edge of the strut down plate (plans mention 13/5 for shaft angle, you previously mentioned 37 for swayback but I think...

Re: LB26 Questions

Shaft axis and strut: I found this in my building notes, page 7: You should start by defining the shaft axis. The shaft axis is shown on the plans. It is a line that starts above the baseline at station 4 and extends to a point measured on the rudder post. See engine installation drawing. Start by d...

Re: LB26 Questions

Shaft angle first. On E 283/6: Shaft angle is shown as 13.5 but, that is only for information. To set the shaft axis, use two points. One is on station 4, 11-1/8 above the BL, the second point is along the axis of the rudder shaft, 26-5/8 below the BL. That is the shaft axis from which everything el...

Re: AD16 Question from Email

It probably means that he doesn't like the cat rig and prefer a sloop. The plans show a spinnaker or drifter, a small jib can be used but it's a cat rig. The cat rig is part of the boat concept, it's difficult to change. It may take a while to get used to it especially if you compare to a standard s...

Re: LB26 Questions

This bothers me. Maybe we are discussing something that is not needed or I misunderstand the question. I know there are no conflicting dimensions because I only show the shaft axis in one place. Could it be that what you are calling the shaft angle is the angle between the BL and the shaft axis? And...

Re: LB26 Questions

I am still on the road and do not have the plans with me but I am certain that the shaft axis is clearly shown on the plans. I never refer to any part of the hull. The shaft axis is a straight line between two points located at two stations with a height above or below the baseline. I will check wha...
