> Hi James,

  Oh Yes......a familiar problem with older Romany's. It will likely be the
Sikkaflex that beds down the hatch rims has failed( Sikikaflex is a Marine
polyurethane  but I could be wrong ) I recall that VCP and NDK both chased down
the manufacturers who informed them that the problem stems from the ABS plastic
of the rims doesn't adhere well to anything. They recommended using a solvent
that softens the plastic prior to applying the Sikkaflex.
All new Romany's have added nuts and bolts/pop rivets but may not solve the
leakage problem if the sealant fails although you will be saved the embarrassing
occurrence of pulling off your hatch cover and finding the rim still attached.
I have fixed them in a variety of ways all which seem to have held up so far.
You had best remove the rims, some come easier than others, some by gently
tugging them and some by levering off with a screwdriver, scraper etc.
Thoroughly clean off the rim and recess being the obvious first step.
West system or similar epoxy works although Nigel says that it won't flex with
the hull but mine has been on for 3 years of hard use.
Marine sealants/adhesives as long as you get knowledgeable advice from the store
or better still 'phone the manufacturers and speak to the Tech. staff.
A two part adhesive containing methylacrylate is amazingly strong and is being
used by one sea kayak manufacturer to bed down all hatch rims with no problems
as yet. Methylacrylate( if that's how you spell it) is one of the adhesives that
Dentists use to glue caps on...so if it's good enough for your teeth.....
I would clamp down the rim before the adhesive goes off but not so hard as to
squeeze all the stuff out. Nut and bolt it with countersunk heads doesn't hurt
but watch out to leave enough material on the rim as the countersink bit may
ream it all away.
I guess an appropriate rational for the problem is that all sea kayaks are a
'work in progress'.
Good luck
Phil Daligan
