Avon sr4 transom/deck questions.
I picked up an Avon sr4, my first ever boat, as a winter project, with an aim to using it as a dive rib next summer. It is quite old (1977 I think if I'm reading the serial number correctly) and I will have to replace the transom and the deck but the tubes and hull are in surprisingly good condition. I replaced a few of the patches on the tubes which were failing and it now holds air indefinitely, and apart from some dings in the hull it is also sound.
When I removed the capping on the transom I can see the ply is wet so it's probably rotten I will replace that, I expected doing this considering its age. About 600mm of the deck at the stern also feels soft so I would like to remove that and replace as much as is neccessary.
I'm wondering, am I better to replace the transom right down to hull level? At the moment it only goes down to around deck level.
And is there anything I need to bear in mind when removing and replacing deck, I can see through the hole in the hull that there are buoyancy chambers below the deck?
I am going to fit a four stroke around 95-98kg so would like to get everything sound and solid so wondering if I should glass knees also from transom to hull?
Thanks for any advice.
Apologies if this has all been covered before, I did use the search bar first! If there is a good thread on it please send me the link.
