[Alberg30] A-4 and Propeller

[Mike Lehman]

The 13x7 prop is the standard prop that came with the boat. 1000 RPM sounds 
a little high for idle, I think you could get that down to 600~800 RPM. Hull 
speed should be achieved using this prop on a proper running A4 in and A30 
at around 1400 RPM.

Hello Fellow Albergers
I am new on this your public-list. I have not sailed in the past 5 years 
having had my boat out of the water. But having sailed all my life, 
returning to the sea  is not difficult. My brother and my self own each an 
Alberg 30. I am asking this question on behalf of my brother.
Question::
His boat has an A-4 and a propeller 2 Blade 13 dia  x 7R pitch. He claims 
that his boat is to fast on docking  3.9 knots at 1000 rpm and does not 
reach cruising  / hull speed  at normal 80% engine rpm. He thinks that the 
previous owner changed the prop and this one is not the right one.
Can some of you A-4 fellows out there just tell me what size/pitch/blade 
propellers are your machines running with.
Many Thanks in advance.
Villo Marmei

PS: I have some sort of pass word for our public-list.....am I supposed to 
show the  pass word each time I send an e-mail to the site or is it the same 
as with regular e-mail????
