Bigger Isn't Always Better
|We decided to replace the seals for our forward hatch (lower area of image) and |
our mid-ship hatch (upper area of image) during the winter
as part of our boat's 30-year retrofit.
|The seal material was purchased from Atkins & Hoyle, the original manufacturer of the hatches. |
I specified that they be 5/8-inch diameter after I found out that two diameters were available,
the other and more standard being 1/2-inch. This was a BIG mistake!
|First, I cut out the majority of the old seal with a razor knife. The groove (shown at the |
bottom of this image) still contains some of the remaining seal.
|Removing the old seal and adhesive was very difficult and time consuming. |
The groove is shown here taped off to prevent the messy
adhesive from getting on the hatch frames.
|The 5/8-inch diameter seal appears significantly bigger than the old 1/2-inch|
diameter seal--it's actually TOO big!
|Not only was the new seal bigger, but without being clamped during curing, |
the seal did not fully seat into the groove in the hatch cover.
