I concur with Dennis on the T slot(s) in the wood strip. Insert a bolt (maybe 
with a washer if room allows) and bond that assembly to the fiberglass.  The 
wood strip provides the needed bonding surface.

Back in 2001 I left the Gibson’s Landing area of Howe Sound to cross the 
Straits of Georgia headed for Active Pass.  We had been anchored in a nice 
quiet bay sheltering us from the much stronger winds in the southern straits.  
By the time we were well into it, turning around was not a viable option and 
the Mrs. voted to keep going while we were still a bit sheltered from the full 
wind and seas.  Out in the Straits, the winds were +- 30 knots with higher 
gusts.  The seas had a fetch from all the way up past Comox and had worked 
themselves into some pretty sporty sailing conditions.  My 11 year old son was 
seasick and asked my wife if this was what it was like in the ocean.  Her 
response (she has sailed back from Hawaii with me twice) was “no, but very 
close”.  My son (between calls to Ralph regarding his Buick) indicated 
something about never going to sea.

For my part, I was enjoying a great broad reach sail with 1 reef in the main 
and a  #3 headsail. It was difficult to hide my smile.  The occasional wave 
breaking onto the foredeck did make the boat more entertaining to drive but not 
beyond my preference for adventurous sailing conditions.  I had the good sense 
to slow the boat and drive off downwind when the Mrs. needed to go below but my 
attempts to calm the motion were not sufficient enough for her to offer to make 
me a ham sandwich or pass up anything better to drink than water.

It was a relatively quick passage to the entrance of Active Pass.  With the 
positive current our SOG was in the 8 to 10 knot range for most of the 
crossing.  Within 15 minutes of entering the calmer water in the lee of Galiano 
Island our son was hungry again and back to normal.  The wind dropped off and 
we motored through Active Pass to spend the night anchored at Ganges, 
Saltspring Island.

My long term family friendly sailing takeaway from this particular crossing of 
the Straits would be to ignore the schedule pressure when the family is onboard 
and the Straits are a rocking.  Out of my approx. 25 crossings of the Straits 
of Georgia, 50% were calm to nice sailing, 15% were in high enough winds and 
seas to be uncomfortable.  This group includes an afternoon caught just north 
of Nanaimo in a forecasted “Qualicum” wind that came on suddenly and blew a 
solid 20+ for 5 hours. (The other 35% were racing.)

Dennis - thanks for the 3M 5200 to bond teak to the fiberglass idea.

David, I agree that bolts are better than screws.

Could bolts be bonded to the hull with 5200 directly without teak or would that 
not have enough surface area?

Martin - Not planning any offshore work at this time.  Will be family cruising 
in the Straight of Georgia.

If you want bolts, recess and epoxy some T-slot bolts from the back side of
the teak before you glue the teak to the hull.

I am looking for knock down strategies so that guests are not laid over to 90

Jeremy,

Will you be cruising in sheltered waters or offshore?

How robust the battery tie down and containment system is should reflect the 
risk of the boat being knocked down.

On Calypso, we have gel cell batteries well secured to bulkhead strength 
attachments.  As we occasionally sail in PNW coastal conditions and from time 
to time make questionable sail choices while racing I expect the batteries to 
stay put when the boat is laid over to 90 degrees.  So far we have only tested 
it to approx. 75 degrees.

If your plans do not include adventurous sail and weather choices you have many 
more options for battery containment.

Sticking things together is only thing I use 5200 for.  It's an adhesive,
not a sealant.

I have GLUED teak blocks to the inside of hulls and on fiberglass bulkheads
for attaching thing very successfully.
