Hello gents, I'd appreciate a bit of a lesson on this please. I can't seem to find a simple explanation, but if there is a link please pass it on.
My daughter decided she wanted a yacht (I couldnt possibly let her down ) so I'm building her the hard chined Aspara from here:
The hard chine lets me build it quickly for her and I have the hull skinned in 1mm balsa ready for a light cloth/epoxy layup.
So I moved onto the keelfin and realized that in my 2 previous builds I didn't have to bother about placement/keelfin angles because my first attempt at a boat was a JIF - and keelfin placement was the least of my worries - and then a Round Ranger that was a kit that had the keel box etc. cut and angled so I just had to get the hole cut in the correct place.
My issue is that on the plan the keelfin angles backwards. Is that on purpose or merely because its aimed at newer builders and that is the angle of the bottom panel on the hull and you adjust the bulb to balance out the boat?
Is it better for performance If I install the keelbox so the keelfin is vertical when the boat is at rest?
And the plans quote top and lower widths for the fin. Does that imply a straight, vertical leading edge with just the trailing edge angled or do both sides of the fin angle in to create a sort of "V" shape?
Thanks in advance
