How many cracks? How bad are they? Do you plan to repaint or regel the boat?

No, I don't plan to paint the outside of the boat. There are numerous spider cracks. What should I do?

I think the advice to purchase the $3 booklet from WEST SYSTEMS (available at almost every boat store) is really excellent advice. You might want to get the book, spend several hours reading it, learn some simple techniques of laminate repair, and then try your hand at fixing the boat.

This will allow you to gain the knowledge to make these repairs. The book is an excellent source of this information. It supplies far more information than can ever be conveyed by questions and answer session in on-line forums.

Go buy that book!

I second Jim on purchasing the West book excellent little primer for understanding gel coat repairs -- and fiberglass in general.

Tspring be forewarned --- if the "crazing" is extensive the only practical solution is have the hull sanded down till no cracks in the gel coat are visible or have it "media" (like sand blasting)blasted and either paint it using a 2 part polyurethane with primer or gel coated again ---

Those, as you call them "spider" cracks, are in the surface of the gel coat and just repairing them superficially isn't going to last, they must be slightly ground open so the gel coat repair will adhere or they will reappear --- Think you can see if you have them all over the hull it will be next to impossible to produce a decent looking finish just individually repair each!

Tspring, I bought a 65 17 Sakonnet? in the early Spring. It had hairline webbing on the outer hull.The boat was used by a clammer here in S.Jersey & was really rough.I cleaned the boat thoroughly revamped the mahoghny. As for the webbing I got the West manual & decided it was too involved to proceed with their method at this time because I wanted to get the boat in the water. I found a product called "Polyglow" that did really amazing results. I sealed the outer hull and restored the gloss. The webbing is still there and I intend to correct it this winter in the garage, as also the inner hull. The boat was great all season, waiting for the Striper's to arrive.
Hope this helps out.

Hi Greg --- well we are neighbors in a sense.

Our boat is at Spring Garden marina over on 47 in Port Elizabeth. Your only about 20 minutes away I would guess. We though live up in Hunterdon County so it is a 2 plus hour drive down --- pain in the butt then again would rather be on the Delaware than Upper Barnegat Bay --- about the same drive time --- used to have a 20 Outrage up at Ocean Gate out of Toms River --- to darn crowded up there during the summer ---

Your 17 sounds like a good boat for where your using her ---

Fiberglass can be very intimidating not to mention time consuming work for sure ---
