Spider cracking around wake tower

Hi everyone,

This is my 1st boat. I've had for a year. Just being ignorant, never even looked at the condition of the gel coat around where the wake tower is installed when I bought. When I started getting the boat ready last weekend, I noticed the spider cracks in the pictures. Fiberglass underneath seems to be in perfect shape. I have an Aerial freeride tower that I really like. Only use to tow wake boards and surfers. We have a ski pylon on my x10 that we pull tubes with.

Is this something that needs immediate attention? I've heard mixed reviews in that it may just be cosmetic and as long as the tower is reinforced properly, I should be fine. I called a fiberglass guy in town and without seeing it he said it often happens from over-tightening the bolts when installed. He said to repair(without seeing the pictures below), he would have to take off the tower and I would be looking at an $800-$1,000 job.

I also included pictures of the metal backing plate. I have seen suggestions about adding wood back there.

Would love to hear thoughts from anyone else who has some knowledge on this. Thank you!

That is a pretty small plate on the back. I would definitely upgrade to a larger one.

I agree, I think it should be three times that. The little surface area supporting the nut is the reason you have spider cracks.

Are you sure this the only plate? In my 2002 Prostar 209 with a tower - there is actually a plate fiber glassed into the hull. I would assume a newer X-10 would be similar.

Thanks, Blackhawk! I agree with you as well. I'll have to go look for one.

I have no idea. I would assume it is. I'll check when I unscrew to put in a larger plate.

Looks like an aftermarket tower to me, so it wouldn't be mounting on the areas that are actually reinforced for the factory tower.

Be sure to clean and fortify (with a wood is a good idea)!

This happened on my old boat after installing aftermarket tower (same brand as yours). If the person installing it didn't drill through the gel coat properly, it can crack like that.

My old boat had really large backing plates, but that area of the hull was just not built to have a tower and I didn't drill the holes properly, so it cracked, even with the large backing plates.

I ran it like that for years with no issues and the cracking didn't seem to spread once it got to about where you are at.

I do agree you should at least add larger backing plates to prevent damaging the fiberglass.

if you are planning to get the gel fixed, then i would glass in some aluminum backing plate, glass around the area to-reinforce and then countersink the gel coat holes to prevent cracking in the future... but if you are not going to fix the gel, just add larger backing plates.
