Look at the inside of the mast base. They have a wear plate that may need replacing.

make sure the mast is strait.

Look at the bows, They have foam blocks which stiffen the bows. If they have broken free then you will see fine spider webs in the gel coat.

Check the skeg for excessive wear from being dragged on rocks or the beach... they are not hobie tough.

Look at the Hook at the top of the mast and the the halyard ring will wear making it difficult to drop the sail.

Make sure the rudders work properly and lock down. Look at the main bolt and the sholder washers in each rudder.

Examine the gudgeons and look for leaks inside the hull... it causes the glass to break down and more leaks.

The hatch covers rot in the sun and are hard to find. replacing them is straitforward with another porthole and 5200

The foot loops rot away in the sun. vacumn hosing and long rivets are easy repairs.

The orginal equipment Tye blocks work but not real well. Most folks upgraded to harken blocks for the main and jib.

check the tiller bar as it fits over the pins on the rudder tillers, the holes will open with wear and make the helm sloppy.

The stock tiller extension is not adjustable, the Hobie hotsticks work well but are heavy. Alu sticks from Murrays are nice but bend if you fall on it.

The Dart tramps are the best... the US made Sunrise tramps are OK.

Pull the rat battens and look at the ends where they insert into the batten pockets. They usually break there. Look at the batten pockets, make sure all of the screws are in and the sail cloth is not torn.

The battens are really crap... you might be able to replace them from Sailsports ltd in Conneticut or directly from Dart in the UK.

Elbow grease will bring out the gel coat and make the boat shine.

You don't need double traps to sail the boat in any breeze under 25 or 30. ... with two boys... you need double traps to keep them both happy.

1000 bucks with the trailer is a good price IMO.

Find Terry Fondrick in the Tampa area ...TBCS. He has had Dart longer then I and can give you some more advice.

Should be great Fun.
Good Luck and Take Care
