Why did it sink? Scupper hose froze and cracked...scupper led to below waterline thru hull
Close your thruhulls...visit your boat after storms/snow
Which brings up a interesting question I have been thinking about these last few days.
Namely, thru hulls. Specifically for cockpit
and scupper drains.
My boat has 4 1.5" thru hulls for the cockpit
to now forespar marelon valves. There are pvc tubing above, then hose to the valves.
Seems to me that a better way to do it would be straight fiberglass
tubes glassed into the hull
, and no thru hulls. For one, why have shut off valves there ? You would never want to shut them off, as the boat could potentialy flood via the cockpit, either via rain (yeah I know a lot of it but still) or taking in green water. Also the thru hulls valves add complexitety to a system that I am increasingly wanting to make less complex.
So wouldn't it be better to just glass in some fiberglass
tubes to the openings in the hull
, and deck
, then connect with a small, say a foot long piece of hose for vibrations resistance rather than the long hose, multiple clamps, and potentail of thru hull failure that most boats have ?
Same goes for the deck
scuppers. I am rewiring so have pulled down a lot of the overheads and teak
covering things to gain access, and have found origianl hose on a 27 year old boat... a accident
waiting to happen. a solid pipe would be better imo, or better yet just a opening in the side, rather than using a thru hull and hose.
Also, when my boat sank at the dock
last year from a failed thru hull due to electolysis, and my rebuilding efforts, I see a LOT of thru hulls (13) on my boat that should/could/will be consolidated to only 6. For instance each sink (3 total) had a thru hull. I will replumb them to a larger grey water tank. The heads are being converted to fresh water flush, so that is 2 more gone. and the list goes on.
I also want to get rid of some non essential openings in the deck. Seems that there are just to many holes in the boat I don't need.
