IceMan Builds a Boat

[IceManDude]

Temp stem frame is now out!!

[IceManDude]

all ties out, keel line and port side all glued up. hope to get the starboard side glued up tomorrow evening... then sanding and grinding all week!!

[IceManDude]

they are unbelievably strong as it is but the fibreglass adds even more strength.

The ply can withstand about 5000psi, the double bias glass is something like 45000psi if the info i was told is correct

Does fibre glassing add alot of strength to those seams - or are they pretty rock solid on their own?

I spose, what I'm trying to ask is - how much of the structural integrity of those seams is reliant on the fibreglassing process. Is that glue just to tack them together and make it all smooth, so the fibre glass will do all the work of providing strength to the seam.

Or could you just clear coat the boat with epoxy and use it as is

For instance -if you stood in the hull and walked along those seams now - do you recon they would hold?

i reckon i could walk along the seams now but the fibreglass is where the real strength is at

Yeah the reason I asked is - when we were kids we had a Sabot - (little sail boat) made out of plywood - as far as I can remember it wasnt glassed - it just looked glued and then varnished but I cant be sure its seams werent glassed.

may have been glued then epoxied... the epoxy is stronger than the glue (the glue is the epoxy plus a glue powder added)

Ahh right - thanks for that

just spoke to my colleague who has been sailing and racing yachts for years and said that the Sabot were built using a stitch and glue (same as mine) and then most likely finished with an "everdure" (spelling??) coating that would soak into the timber and stop it rotting out etc.

and thats about as much as i know...lol

Ha, I owned a manly junior as a kid. Pretty similar to a sabot but with a jib and spinnaker. We always fibreglassed the chines and keel inside and out, more for waterproofing and ability to take few knocks rather than strength.
This was back in the early 70's, long before the stitch and glue technique was around. Everything was epoxy glued and copper nailed if I recall.

Yeah this sabot was bought second hand, about 30 years ago and now that you mention nails - that sounds about right.

My Dad used to make his own canoes and surf ski's. His experience with Fibreglass came in handy in repairing the hull after one too many high speed beachings on to the rock lined shore.

We also found a sunken pedal boat which was raised and salvaged with the assistance of fibreglass - it lasted about a week before we found that the rotting hull couldn't take 8 fully clothed kids trying to cross the lake on a chilly afternoon

Just imagine this with 8 kids in Desert boots and 80's woolen jumpers hanging off it
