[Public-List] Biminis and Raising the Boom

[Michael Connolly via Public-List]

James, 
I have heard back from David Terrell. He is OK with sharing information/my photos of his Bimini/Dodger combination with the list.  I am planning on getting with George to get photos/article posted on Alberg 30 Web Site. This might take a few days. 
  
I did have a brief discussion with David this morning and he raised his boom "a few inches" using the original boom slide on the mast enough to achieve his request of a 5' 10" headroom in the cockpit.  No modification had to be done at the original mast/gooseneck juncture.  David did have a new mainsail mfg. at this same time to accommodate the higher boom. 
  
You might see if you can achieve full hoist of your main and see where the boom rests. If there is enough cockpit headroom for you to stand then you are golden. If you fix the gooseneck in place on the mast at full main hoist then use a Cunningham to trim the main luff instead of the original downhaul you can achieve luff tension adjustments without having the boom raise and lower.  Many Alberg 30 mains have been mfg. short so you might just get full hoist with the boom height where you wish to have it to clear your new Bimini. 
  
More on David's arrangement when I can get my photos to George.

Subject: [Public-List] Biminis and Raising the Boom 

During the discussion about Dodgers and Biminis there was mention about 
raising the boom. Are there any suggestions for how to best accomplish this? 

On my mast there 2 tracks, one that the sail hanks on and one the boom 
rides on. 
 There is about 4 inches between them. when hoisting the sail the boom 
rises until it reaches the boom stop ( a bolt head at the top of the boom 
track).  Tightening the downhaul brings the boom down 2 - 2 1/2 inches. 

I am thinking that I would need to move the boom track up several inches 
and remove an equal amount off of the bottom of the sail track.  I would 
also need to lower the headboard on the sail. 

Is my thinking correct or is there a better way? 

As always all advice is greatly appreciated.
