Having just joined your Forum I am looking for ideas from the collective to resolve a problem with a boat I bought recently. Wouldn't be a boat if it didn't have problems!
Freyja is a 17' daysailer - gaff rigged, cedar strip planked and epoxy/glass fibre sheathed internally and externally. She was professionally built in 2000 by an experienced and respected boatyard using WEST materials and specification.
Only 1 previous owner who bought her at a boat show
and apparently she had only been in the water
twice over the last 14 years and sails
etc suggested this may have been the case. She was borrowed by the boatyard in 2006 to use as a boat show
model. Some evidence of water
lying inside the boat for a period of time at some stage.
All well until I started to remove the antifouling to refinish with coppercoat when I discovered that the white paint
on the hull
(high build primer) beneath the antifouling was covered in a myriad of fine cracks. When this paint
was removed I discovered that the cracks are actually in the outer epoxy
layer. In a couple of test patches I found the woven glass is still properly bonded to the cedar strips and the cracks do not appear to extend into the epoxy
glass matrix. Neither the boatyard nor WEST have encountered a similar problem. The sheathing regime was saturating the cedar with epoxy, applying Glass fibre sheathing, saturating the woven fabric
and then a final layer of epoxy on top of that.
I am currently continuing to remove (slowly) the white paint and the outer epoxy layer without damaging the glass fibre. I am hoping that the initial test patches are representative and that the glass fibre sheathing is not compromised.
I am hoping to avoid having to remove the original sheathing, clean back to the cedar strips and re-sheath according to the prescribed WEST system.
I would be interested if anyone has come across such a problem, how it might have arisen and how it was rectified. I have attached a not very good photograph. Well I think I have attached it.
