Reply to: Nacra 5.0 mast base casting removal and re-sealing

Message body

[quote=Edchris177]As Damon said, the extrusion is still the same, the base looks like a different shape, but my understanding is that only the little "pointy end" was removed on the captive base. 
You don't need to seal the portion where the old base covered the sail track, only the main section. The new style base should slide into the extrusion, just like the old one came out.
I have one of the lower rivets on that small eye strap left unsealed, with a small plastic "stick" pushed into the hole. I put the stick in while sailing, & pull it out (tie to a string to prevent loss) when done, to allow any water to drain.
Eric, I agree that lying on your side for hours won't sink the boat. What changed my mind was being blown over in 30 mph. As soon as the mast hit the water, about 1' of the sail goes under. The strong wind pushing on the tramp drives the boat quite quickly. The mast/sail is on an angle in the water, & it drives down like a chisel going into butter. The mast does not have enough bouyancy to counteract this. My 5.7 turtled in under 5 seconds. 
Luckily, I managed to get it wrestled back on its side, with the mast upwind fairly quickly. Afterwards i realized that any unsealed portion of the lower mast would be underwater while turtled. Even 1 gallon leaking in would now be at the mast head, & righting would be a b.i.t.c.h.
If the mast were to fill, i think it would weigh several hundred lbs, I never want to attempt to rescue that situation, so i sealed the entire mast, & put a float on top to make sure it can't turtle.[/quote]
