<p>I am looking at a tiki 38 that has been sitting in a tidal area that has been damaged and neglected. There is a fairly large whole on starboard hull on the bottom and the bottom of both rudders have been knocked off. There is some delamination on the port hull in the inside rear corner. I need to move it a few miles to an area where I can fix it and was wondering if someone had a quick temporary fix idea for the hole and the delamination till I can get it to the beach in front of my house to…</p>

<p></p> The effects of UV, the hammering heat and humidity on Epoxy and Wood joints.tag:wharrambuilders.ning.com,2014-10-24:2195841:Topic:1226752014-10-24T05:54:42.135ZGeminidawnhttps://wharrambuilders.ning.com/profile/Geminidawn
<p>Back in the UK the greatest threat to a varnish finish was moisture ingression, lifting your finish and the green house effect which promoted the growth of the dreaded black spore fungus.</p>
<p>But living in the tropics is something else! I cannot believe the damage UV, Heat and Humidity inflict on epoxy and wood joints. even those that are coated with paint.</p>

<p>Back in the UK the greatest threat to a varnish finish was moisture ingression, lifting your finish and the green house effect which promoted the growth of the dreaded black spore fungus.</p>
<p>But living in the tropics is something else! I cannot believe the damage UV, Heat and Humidity inflict on epoxy and wood joints. even those that are coated with paint.</p>
<p>Both masts were built out of what's locally known as Igem (Podocarpus Imbricatus) better known to the rest of us as Yellow Pine. They were built as per plans, long scarfed lats, rebated to form a dodecagon and then rounded. The first mast was built in my absence using Ampreg (GL approved) and looked great! But when I got back, though it was stored indoors, I noticed some of the seams started to open up. I put this down to poor preparation of the wood or a poor resin mix ratio. The building of the second mast I supervised myself, the preparation was good, moisture levels checked and the resin , Epolam, this time (Lloyd's approved), was weigh accurately using a digital scale.</p>
<p>The work was done and it all looked great. The masts were primed and varnished, same as "Gaia" prior to being moved outside to the assembly point. Since the masts were to be the last things fitted to the ship. they were covered with a light polyester cloth, laid on trestles and set to one side while my apprentices and I got on with the rest of the work.</p>
<p>Within 9 months I cannot get over the amount of cracking, splitting. shrinking and movement in the wood, varnished surfaces especially seem to come out worse but painted surfaces are not safe either as the constant expansion and contraction soon results in hairline fractures on the joints which are then vulnerable to moisture ingression .</p>
<p>I built a Wharram Catamaran to sail to, and to sail in warmer climates, I guess I just have to resolve myself to the fact that owning a wooden boat, especially in the tropics is going to take a hell of a lot more vigilance and maintenance than owning one in more northern climates.</p>
<p>Again like Gaia, it looks like I'll have to now paint the masts if I want to get any longevity out of them, I'll also have to order a long pair of socks from the sail maker that can be stowed at the mast bases and raised using the halyards when the boat is moored up just to give them some further protection from the hammering sun. </p>
