Posts: 324 South Florida | A couple of questions for anyone who may be able to help. First, i am trying to remove one hull for some repairs. All the bolts came off with the exception of the bolt that holds the front crossbar to the hull on the inside (an allen wrench type bolt). It is completely stuck and I cannot budge it. I tried spraying WD 40 in there but to no avail. I am afraid that if I keep trying to force it, it will snap off (I have done this many times in other circumstances). Anyone know what the heck to do at this point?? The second question relates to the reason I am taking the hull off. There are cracks that have gone through the fiberglass about 4 inches long to each side of the place where the cross bars attach to the hulls. I am taking in about a bucket and a half of water from these cracks. The cracks are right under the lip of the deck at these locations, but do not go through to the deck. I was quoted $300. to repair and reinforce these cracks by a local wood boat builder but he wanted me to take the hull off myself. Does this price seem reasonable?? Has anyone had experience with this type of cracking on an TheMightyHobie18?? Is it easily repaired (assuming I don't break that allan bolt head off)? Any comment or help would be appreciated. (I have been off the water for THREEE WEEEEKS now ). HEEEEELLLLLP! FRED TheMightyHobie18

Posts: 324 South Florida | Thank you all for the advice. I am going to try all of the above to loosen the bolt. I already looked at the Hobie catalog for the replacement crossbar attachment. 180 bucks (ouch). I will proceed with care and patience. Msopum, I may ask you for more advice if I decide to take on the job myself. I love to do this type of work but am limited in time. Did it take you 3 weeks because of curing periods etc.? holy cow! I think if I stay off the water another 3 weeks I am going to forget how to sail!! MMiller, Regarding the end of TheMightyHobie18 production, do you know if replacement parts will still be in production?? Thanks again all!!

Posts: 805 Gainesville, FL 32607 USA | There was a thread on this repair a few years ago. I have repaired 4 Hobie 18 Magnums, all of which cracked left front and right rear under the crossbars, both inside and outside lips. All Magnum sailors should check this.
These boats were not designed for such a load- the excess torque of wings-- sometimes with 4 adults on the weather side wing. Only the early 1978-79 Hobie 18s cracked here (or pulled the decks off) before wings: the D-shaped reinforcing plates then became essential to long Hobie 18 life. I still have 2 of these ironclad beasts!

Posts: 324 South Florida | Mine is an 85 Hobie 18. The main crack is on the inside of the starboard hull (foward crossbar), although all the others are showing slight cracking to spider cracks. Luckily the hatch is right next to this crack so access problems are not as much of an issue. By the metal plate reinforcement do you mean the "u" channel washer type plate? Because all 8 locations have these. But the cracks start a little beyond these plates. I will look for that old thread on this repair
Thank you,
