Typhoon WE Thru hulls and seacocks

[Rick Gedney]

New owner here...

My 76 ty has all 4 seacocks rusted and frozen and I am looking to replace all thru hulls and seacocks and cockpit hoses. I have a few questions:
1. If I never plan to use a head (port-o-pottie is fine) should I just seal up the large thru hull on port side for this ? or even glass it over?
2. What the heck does the other forward thru hull drain? Starboard side.
3. I have see on line one on forum a few different options for cockpit scuppers, hoses, seacock, thru hull? What is best? Are the resources on owners page a good resource for this?

Thanks

Rick G.

Hi Rick,

Congrats on the new boat. Now the fun starts!

My 76 TyWe (#1176) was equipped with the factory head -- they were direct discharge (ah, the good ole days ). Anywho, it used two thru-hulls -- one in and one out. That's likely what you have as well. I pulled them and glassed 'em over when the boat was on the hard.

Enjoy!

With respect to the cockpit scuppers, hoses, etc., you may want to consider not installing seacocks. My Cape Dory Typhoon Weekender (No. 1400) did not have seacocks, only hoses going from the scupper drains to the thru-hulls.

Others may disagree, but on a Ty Weekender you really do not need seacocks for the cockpit. They will always be (should always be) in the open position. Should you "spring a leak" plugging the thru-hull is easier without the seacock. There is a thread on this board discussing the issue of seacocks versus no seacocks on a Ty Weekender. I can't find the thread.

Someone recently posted a photo of their cockpit scupper hoses below the cockpit (white hose; white paint). I cannot find it but I know I just looked at it 2-3 days ago. It is simple, elegant and works. With respect to the hose make sure it is as close to a direct gravity drain as possible to avoid an airlock and the cockpit filling up with rain water. My Ty had a "loop di loop" (highly technical nautical term ) that created an airlock whenever there was a heavy rain. I removed the hose, made it shorter (removed the "loop di loop") and replaced the hoses. Worked great.

Good luck

I agree that if you are not using a head properly glass up the forward through hull holes. The cockpit scuppers need to drain however so you should be able to fell good about them.

You can decide whether to have a seacock or not but I removed the original gate valves on our Ty and installed Apollo ball valves on the through hulls, 45 degree elbows and new shorter hoses which still work fine after 20 years (My friend now owns our old Typhoon). We are in fresh water however. Search Typhoon Through Hull Replacement on this board and I bet you may even get part numbers for the job. It was amazingly helpful to me all those years ago.

This one thread on this forum alone is worth the CDSOA dues and then some. Thank you all. I will glass up the forward thru hulls and now I need to decide if I am using a seacock or just a hose on the cockpit scuppers. Why do you think the original build had gate valves on these thru hulls ? What would have been the purpose? Perhaps just standard practice at the time.

Again thanks much.
