keel accident

Postby villalonso » Sat Sep 03, 2016 9:42 pm

Hello everyone

I want to share with you the accident that happened at "Villalonso" in early August, when sailing near the island of Portichol near Jávea in the north coast of Alicante. By going to drop anchor, we went through a shallow area but initially had sufficient depth. It was not so and going to 3 knots collided with a bedrock. We gave astern immediately and we solve the situation.

The coup made us fear for the boat, but after a first inspection no leak was not found. We continue to our base port and once the boat in dry dock check the damage shown in the photographs. In addition to the keel, the cooked cardan is broken, which has forced us to modify the support, as shown in the photo.

The repair was carried out after three days dry to avoid internal humidity, fiberglass cloth and epoxy resin was placed to recover the shape of the keel, which had previously been machined to clean up the hitting area. It ended with the corresponding layer of protective paint of the hull

Greetings from Altea on the Spanish Mediterranean coast

Hi Antonio!

Sorry to hear that but it seems like you were able to deal with the situation quickly. It is of course important to check everything after the grounding, but I found it unlikely, that even a hard grounding would result in leak in case of HR29 as the keel is uniform with the hull. However, it is important to dry and fix the keel area properly.

We had similar contact at speed of about 3 knots with Norwegian bedrock in 2011. Here are a couple of photos from DD's keel after the grounding and the subsequent repair.

Hi Antti

Thank you very much for sharing your experience, I think we had the same sense of concern when we aground. No photographs when I noticed the "Villalonso" but from what I've seen in your post, the procedure was the same, using wool fiberglass and epoxy resin. From what we can be satisfied HR29 owner's is that it is a robust and safe ship

best regards.
