Topic: Water not draining from hull |

There are one or two leaks in my buzz, and I've noticed that not all the water dreains out of the bung. Once it's finished draining it sounds as if there is a significant amout left in the boat. Even when I've tipped it up as far as possible.
By feeling inside the bunghole it seems there is a lip that would prevent all the water from draining.
However, I'm not convinced that there isn't something else stopping the water from draining, it sounds as if there is more than would be contained by the lip. Is there something else in the hull that could get blocked? A channel between ribs, or something like that?
If I put a hatch in the transom, presumably I will be able to sponge out any water that's collecting in the stern. I'm not sure if this is worth putting another hole in the boat!
I think the leak is the seal around the daggerboad casing. The sealant inside the slot is either hard and brittle, or not there. What do I need to use to replace this?
Any help would be appreciated.

Hello again,
I always fit a bouyancy hatch the same as later boats. There are several reasons for this, one is that you can sponge out any water that is not removed through the bung, two is that you can get to the back of the rudder fittings (i normally replace the rudder fitting screws for bolts) and three the hatch cover can be left off when the boat is not in use allowing air to circulate around the hull and hopefully help to get rid of anymore damp in the hull.
Dispite the above you obviously want to eliminate the leak and the places i would look is along the gunwale for any splits along the hull joint (if you turn the hull upside down any water will probably leak out through any splits here), around the spinnaker pole hole for excess wear/ splits, and definately seal around the centreboard case to eliminate the possibility of a leak here. I use sikaflex around the board casing, which will probably mean you'll have to replace the fluffy stuff around the top of the board casing at the same time.
I hope the above helps.
Stuart. |

Interestingly, it's fresh water in the hull. I've reseated all the deck fittings, so if it was them, it isn't anymore.
I cut out for the hatch, but either I put it in totally the wrong place, or, or I don't know what.
My understanding was that it goes in the vertical part of the transom that the rudder hang off. Surely it must go there, else how can you get to the screws of the gudgeons?
But this doesn't give me access to the hull cavity proper - there is a floor to the transom post (for want of a better word) that means I can't actually sponge any water out - which was the point of the whole excercise! |

It is fine to remove this part of the 'floor'. The later boats with a hatch dont have this bit of floor anyway. It is a bit of an awkward job and make sure you remove any sharp edges to prefer injuries at a later date whilst sponging the water out!!

Also check around the pole as this area gets a lot of wear.

I've checked the pole and didn't see anything, though another look can't hurt.
Offtopic, the pole itself needs some tlc. The paint/coating has come off in places which can't help with launches and drops. How's this patched up? |
