hollow keel comments - Marty Clough

 

Hello Richard

Phil Bolger was kind enough to respond to questions I asked about the hollow keel on Chebacco.  I thought you might wish to include portions of these two attachments in the next newsletter.  My own Chebacco is covered for the winter ( cheap plastic tarps) with much work to be done before I get to the keel.

Dear Mr. Bolger,

 

I purchased my Chebacco plans from Dynamite Payson rather than directly from you (an option I wasn’t aware of somehow) so I understand you may choose not to comment, but I have a question about the hollow keel.  Some of the builders seem to build to plans but many opt for a solid keel, built up various ways.

 

I would be pleased to build to the plans (especially after reading your comments about the Reiver) but I am concerned about marine growth on the inside of the box (the boat will sit on a mooring in Tashmoo on the Vineyard, where water temperatures and nutrients allow fast growth of unwanted stuff).

 

·       Won’t barnacles and sponges and all sorts of growth occur on the inside of the box, possible creating

o      Deterioration of the box

o      A horrible smell when I store the boat in my backyard

·       Other than building simplification, are there strong structural drawbacks to making a laminated solid keel?

 

My Chebacco still has a ways to go, but I am finding it an entertaining and challenging project.  If you can comment, I would like to share your comments with the Chebacco.com website which has been a good source of continuing inspiration and support.

 

My brother Brad got me started as a Bolger-phile by purchasing a Gloucester Gull from Dynamite many years ago and car-topping it from Maine to the Vineyard ( he still has the boat more than 30 years later).  I’ve built the Teal (my wife’s favorite) and Bobcat (“tiny cat” -with a Beetle Cat mast and sail) and look forward to your honesty in boats, books and Messing About.

 

Sincerely yours,

 

Marston Clough

Phil Bolger responds:

 

“The first boat I did with a hollow, free-flooding keel was launched in 1972.  I had the same concern, but in fact it did not happen.  We took one side off after several years and found the plenum perfectly clean.  We’ve done quite a few since and not trouble has been reported”

 

“The object was to avoid the shrinking and swelling of the components of a solid deadwood…”

 

“A solid keel or a skeg built up wholly of plywood would not have this problem; it would be that much heavier on the trailer.”
