[Rhodes22-list] Mainsail slugs (was Mast Crane) (was Lou Moore)

[Rik Sandberg]

Roger,

No, don't go making any special trips. :-) I appreciate the thought. By the 
time you read this and could do anything, I'll already be a couple hundred 
miles from my computer. 

I never gave it a lot of thought at the time, but as I remember, the top two 
slugs (the one on the headboard & the top one on the cloth) weren't all that 
far apart. As you say, maybe only 6 inches, give or take a bit. It probably 
isn't going to be an issue.
