Re: supplemental downwind sailing configuration for Super Maramu


James Cromie
 

Looks great. This is exactly what I’m looking to for!  Thanks for your measurements.  It looks to me like you’ve had the sail designed so that the foot easily clears the bow pulpit, while your furler is down below and I’m assuming it has adequate clearance from the headsail furling motor housing.  

Any troubles with chafe up at the masthead?   

I’m thinking of using the Profurl Spinex 2.5 which will accommodate a sail up to 130 sq. m. 

How high into the wind have you used the spinnaker? 

Many thanks,
James

James,
I have an asymmetric spy on a top-down furling RollGen 20 by Bamar. 
Spy dimensions:
Luff=17.07mtr
Leech=15.4 mtr
Foot=7.9mtr
SMG=7.105mtr

I have enjoyed it for more than 6 years with the main advantage of being able to deploy and furl back with just my wife, something that is a major plus for me.  Also, it takes a lot of turns to furl but we use the electric winch to do it.
It is also important to make sure that the apparent wind is not less than 90 degrees or more than ~150 degrees to furl correctly.
A couple of times we totally lost all wind and furling could be done poorly and had to be redone as soon as we got back some wind. 
Here are a couple of  pix of Ipanema under spy
