ex Finish navy SR6 build

Warning! Some of the pictures in this thread may be too shocking for some audiences.

Hi!
I have been away for quite a long time. Since I have had no inflatables for some time. But it all changed four months ago when I won my first proper RIB from an auction. I was quite sure that I would not get this boat and just left my highest bib in and closed the browser. After a while a message came and told that I was the winning bidder

So I went and collected a former Finnish navy / coastguard Searider 6.0 from a guy who had bought it from another auction held by military. This raised some concern in me but I was blinded by the fact that I finally owned an Avon Searider. And hey it was dirt cheap and I was no stranger to glass work.



After I got home and made a more proper inspection I thought that it would not need any too major work. Just some paint and some elbow grease.. Then I gradually dug deeper and deeper.. Started dismantling everything.




Some of the ply on the floor plus on the stringers was wet and coming separated. Most of the damage was on the aft floor and stringers. There was some minor wetness on bow also. The stringers around the fuel tank were mostly wet but middle section of the deck was completely dry. It was apparent that the damage was due to leaks through improperly done deck fittings and some drain holes just drilled through stringers.



At this point I thought that I could re-use the “precision cut” layer of the deck when putting all together again. I was sure that I just needed to change the top part of the deck.



continues on the next post..

part 2.

So during these 4 months I removed all of the wet ply and constructed a new structure using about 25kg of epoxy, glass and birch plywood.


I used a tungsten carbide disc on a grinder to dig out the wet ply so I could then push the fresh board under the sidewall. There is a foam core behind there.







To save some effort and money on epoxy. I used chainsaw, multimaster and various chisels to remove wet ply from stringer cores and simply embedded new wood with epoxy on the cleaned up slots.





I made everything just about the same way as it was made on Avon so I did not alter the design very much. Just cut some corners where the design was overly complex and used a bit more wood than there was before.



continues on the next post..

Part 3.

After the stringers were done I laminated in the new deck ply.

Part 4.

I used epoxy with various fillers and additives. Here I have epoxy paste with chopped strands and colloidal silica topped with glassfibre cloth. Used staples to hold the mat in place during the laminating process. Most of the mat I used was 800gr./m2 combination of bi-directional and chopped strands. And finer woven cloth on top to leave finer surface.





The aluminium deck plate was in kind of a sorry state. But it was sent to be sandblasted and powder coated.

Part 5.

Drilled some oversized holes to the deck for the hatches.


Every single bolt and fitting is embedded in epoxy that is cast on oversized holes. So this tragedy won’t happen again in any time soon. All the wet areas on the deck and stringers were due holes on the laminate. Fixings and drain holes.








This is where I'm now with this project.

I still need to re-upholster the seat, remove the paint from the console and paint it gray. I have to find an engine and instrumentation. Re-wiring needs to be done and finally I need to do some kind of anti-skid paneling / paint on the deck. So to be continued

It has been really difficult to find good second hand engines on my price / power range. I'm looking for a 2003-2010 Mercury Optimax 150-225hp. Or maybe Yamaha F150. Or something similar.

Today I worked on my garage since the weather is starting to get really cold and it was very windy. Luckily I have finished most of the work that needs to be done outside. I removed paint from the console with a rotary wire brush and an air grinder. The console had been soaking in paint remover over night so it was quite easy task. Then I removed all the wet ply from the bottom part of the console. I was able to save the original laminate on the outside by chipping the ply off with a chisel. This was quite arduous. Then after everything was nice and clean I epoxied new pieces to the surface.

Anti-Skid

I was thinking of using this kind of rubber matting for general protection as well as for anti-skid purpose. It's mostly recycled tire rubber combined with EPDM granules. Any thoughts on this?

PVC Gummigranulat Fb. 865 asphalt - raumprobe.de

This would then be glued to the deck with 2K PU glue. It's really cheap but I like the look of it. Usually used on gym floors, acoustic dampener etc..
