Trimaran - Especially Searunner - Owners

[YMan]

Do you think it's possible for me to remove my centerboard on my 31' Searunner while the boat is still in the water? I'm having a hard time finding diagrams online.


This is from pg. 188 of Jim Brown's Searunner Construction Manual, "Installing the board while the boat is in the water is not difficult. The amount of water which comes in

while the cap is off the gland is very little - hardly a spongeful if you’re quick - so pulling the board for

maintenance while the vessel lies afloat is definitely possible."

i talked with a fellow today that is selling a Searunner 37. She is a project boat, and has some rot in the bow, the water got in thru the chainplates or so he says. He mentioned a sacrificial piece of wood that is rotted in the bow. i have never heard of this. Anyone? Also the keel has a rotted sacrificial wooden plate that needs to be replaced. She has a 13hp Volvo diesel. Seems underpowered to me. She also has a bowsprit that is used for the gennaker. Has anyone ever seen a Searunner 37 with a bowsprit?
thanks

That looks a lot like what the man described as his modification. He uses it for a DRS (?) - a gennaker - to get more sail area forward so he can still use his headsails. Claims that in light air he can put up several thousand sq ft of sail. Can we say 5 knots in a drifter? He uses a permanent bobstay and shrouds to the floats, and it is held up when not in use by a halyard.

He claims that there is no rot in the kingpost, just in the bow. Dunno what he means by that. i'll be busy moving 12 hours away, so i have no time for a boat rite now, especially a project boat, but maybe things will change in the fall or winter, (spring 2020?). This 37 is 4 1/2 hours away from my new location.

Not permanently. There is a pocket knife or something severely wedged between the board & trunk wall. I've already tried the halyard winch & several other methods but I can't seem to get it unstuck. Maybe if I wait long enough it'll rust away 😆

Drop a lightly weighted 3mm spectra line down beside it, then use a piece of stiff wire (like 9G fencing wire) to hook it back up the other side of the obstruction.

Attached both ends of line to winch. Extract obstacle vertically.

Might work....???

[rossad]

Buzzman is right. If you can get a thin line spectra around it and back up and winch slowly. I like that idea a lot. I had a piece of particle board down in mine and it swelled.
When i bought the boat and sailed up the coast of NZ. Not a good idea because I got blown offshore and it took a couple days to get back in view. It was when the wind changed I was able to make way west again. For my first off shore experience I was concerned. No centreboard made it a serious situation.

have done some transports with a searunner 31. very spartan inside but very functional. handles sea well. not a fan of the center cockpit and transport can get very wet (good weather gear">foul weather gear a necessity) and this particular one (tiller boat) steered like a bit of a pig but overall a decent boat for coastal cruising.

[Buzzman]

Is this derelict a Searunner? Backward sloping rear window and interior shots suggest it might be....

If so what length do people reckon? I'm thinking longer than 31'..

Definitely a Searunner. I think it's a SR37 going by the size of the aft cabin portlights and shape of the sterncastle window. The SR31 doesn't have a portlight in the side of the aft cabin and it's quite a bit shorter. The SR34 has a smaller portlight.

[Buzzman]

Yeah, I was pretty sure it was an SR, but not sure if 34' or 37'.

Looks like a MAJOR project, as it has been sunk and contains rot. Also looks like the rudder blade may have snapped off and who knows about the centreboard.

But it's only the second SR I've seen for sale in Oz in a couple of years. Last one was a spar-wing 31' that sold like that {snap}

I think she is Tritheam. I remember her vaguely from the 90s when I looked at Searunners to buy. Makes me sad to see her like that.

Some of these Searunners were epoxied but if not this one could be on the way out. I think it is the 37 with the mast in the cockpit, 31s had the mast in front of the cockpit. The 40 had a longer deck aft of the sterncastle compared to the 37.

In my youth I would have jumped at this boat, but now I have boats of my own already. Maybe someone will grab this one, but I would check her closely for rot.

[Buzzman]

Definitely looks like a major project to get her sailing again. Sad.

[slowbat]

Having done a major Searunner restoration I would not take this on. I wish I had just use all of the bits and built new hulls. Might be worth saving the parts for a new build.

[rossad]

Yes it looks like a SR 37 to me. Same as mine. That is a bit sad to see such a photo. It needs a years work and you got a good boat.
