5.4m Searider project

[murph06]

Hi everyone, I am looking for advice on repairing a 5.M sea rider.

I have a hull which is in good enough nick except for the transom, the marine ply is rotten due to unsealed holes.
It is a twin engine model, which I plan on changing to single.

The plan is to strip away the fiberglass on the inside of the transom, replace the rotten ply with good quality marine ply and re-glass over it, I plan on filling the centre self bailer hole and making two new outer holes.

After repairing the transom I want to refinish the hull with a new gel-coat, what I want to know is will I be able to achieve the same finish that is on the deck of the boat over my newly repaired transom?
I want to keep the finish as original looking as possible.

I have new tubes to fit to the hull, the tubes are the standard grey and the hull is orange.
I don't know whether to leave the hull orange or have it refinished in grey.
I have heavy duty black straking, probably more than enough to do my boat, and would like to put it to use. But when it comes to a pattern or configuration for the straking I am completely lost.

I have no engine as of yet but would like a Yamaha 90 2 Stroke, I have new Yamaha gauges and controls ready and waiting.

I have new cable steering ready to go and I am going to use the standard seat and console, refurbished of course.

Any suggestions would be greatly appreciated, I will try and post some pics soon.

I forgot to mention my Father is a shipwright and will be helping with the build.

Thanks in advance, Murph.

The outside of the transom would have been gelcoat and the inside flowcoat. It should be easy to get the inside of the transom the same finish as the deck.
As for doing the gel coat me and my mate managed to get my 5.4 flipped over pretty easy, mine hasn't got the tubes on at the moment so no worries of damaging them.
The grey tubes and hull looks smart, I was going to go that route but got hold of a orange console in decent nick and it seems a shame to paint it.

You'll have to get some photos posted.

Also looking for an A frame, probably get one made?

Is there anyone doing readymade frames?

[murph06]

Is the flow coat the stippled effect on the deck? I thought it was just gel coat applied differently?

Would it be ok to apply grey gel coat over orange?

[chewy]

Gel coat needs to be air tight (I believe) ie in a mould to cure. Flow coat has a waz added to it and it'll dry in air.

Flow coat is usually used on the inside of lockers etc. I'm not sure if the grey will cover the orange?

I think this stuff should do:

I was under the impression that you could have a gel coat sprayed on?

I covered the original orange deck of the osprey with white flow coat and it covered with no problem

Does the flow coat cure as hard as gel coat or is it kind of rubbery?

It hardens the same as gel coat, it is the same as gel coat but with a wax added to stop it having a tacky surface when it is hardening as it exposed to the air whilst curing.

What kind of money am I looking at to get my tubes fitted? I was quoted 2000 Euro already by Lencraft.

[chewy]

Have a serch for Lencraft on here first.

I've been quoted anyway between £270 and £700. Or if you have a big enough garage do it yourself?

[murph06]

Wouldnt have the balls to take it on myself, probably make a mess of it.

Theres a place near me called Cara Marine, they carry out rib repairs,
getting a quote today, fingers crossed!

[murph06]

got a rough qoute of 1500 euro to have my new tubes fitted, happy enough with that.

The workshop looked fairly busy and the workmanship on the ribs being repaired/refitted there was of high standard.

Hope to have the hull in the shed by the end of next week and start stripping the transom.

Cheers Richard, I had a look into changing the colour of my hull, too expensive and too much hassle!

I will use flowcoat to refinish the deck after the transom repairs, will I be able to get an orange flowcoat to match the Avon orange?

You should be able to get flowcoat to match the Avon orange, CFS do 2 orange pigments (tangerine and pure orange) and other companies do other shades. CFS are very helpful worth giving them a ring.
I sprayed the hull with International 2 pack perfection paint a superb finish but you have to be very careful if you spray it, you need to wear a respirator, international recommend brush and roller.

Have you got very far with your rebuild?

I've got a 4m searider which needs similar jobs doing to yours (new transom, refininsh hull gelcoat, possilbe new deck and some tidying up of the tubes) and was just wondering if you had any tips or had any major problems.

My plan is to screw a sheet of 6mm ply to the transom to give it some strenght while i remove the inner glass and rotten ply and then replace the ply and inner glass, a bloody good sand of the hull and insides and flowcoat the whole boat. CFS are doing a special offer at the moment on their grey flowcoat so the hull is going to change colour from orange. I having a 2mm stainless u section fabricated to cap off the top of the new transom that will extend down far enough for the transom support bars to bolt through it.

A few questions for the Searider proffesionals -

• What thickness ply should i use to replace the rotten ply in the transom?
• I think the ply in the deck is rotten in places (the boat has been afloat for 10 years!), I'm considering blocking off the flooding hull, whats the best options for sorting the deck? dry out and simply reflowcoat? cut it out and replace the whole thing? dry it out and reglass a piece of 12/15mm epoxied marine ply over the top before flowcoating everything?
• Roughly how much flowcoat will I need to do the hull, transom and insides (basically the whole boat) and whats the best way of applying it? thinking roller it on and brush it out.
• Any other suggestions for replacing the rotten transom?
• Apart from fast acceleration will the handling be affected much by blocking off the flooding chamber?

I'll start a new thread and post some picture when the boat comes off the water and work starts.

thanks

Hi Hamster, my rebuild has ground to a halt.
I have nowhere to work on the hull at the moment, looks like I will have to rent a shed after Xmas.

I looked into changing the colour from orange to grey, but it just seems like too much hassle not to mention extra expense.
I will flowcoat the deck after the repairs.
The underside is in good enough nick, just gonna give it a good compound and polish.

Don't know whether to go with the standard rubbing strake setup when I get it retubed or go for something different, I like the look of the SR4 on the ribcraft site, might try something similar.

If your looking for ideas or advice, Matt H and Nos4r2 are the lads to talk to!

shame you've not managed to get very far. It's a bit cold to be doing much work out side at the moment!
I'm looking at changing from orange to grey simply because the whole thing need reflow coating and cfs are selling grey off at the moment for about half the price of orange.

I saw the 4m on ribrafts website and it does look pretty smart. I think a single rubbing strake looks a lot less military/commercial than the 3 fitted to a lot of seariders.

I'll try picking matt and nos's brains when i get the boat out the water after christmas

Is it the same grey they used on the military 5.4s and where/who is cfs? I could do with some.
