Timber boats in hot, sunny, Weather

[Debennut]

I have owned wooden boats for many years, and always worry about the effect persistent, hot, sunny weather has on my boats timbers. (Iroko on oak frames)

Probably irrational, but has anyone had experience of problems as a result of this current weather?

My varnished cockpit is covered, The cabin sides have had several coats of "Sickkens" one recently and the decks (grp sheathed) were repainted during the last winter layup, the top sides have three coats of white weather shield over primer.
Should I be concerned and if so, apart from having an overall cover made, what should I do about it?
Thanks

Sounds like you have done all the right things. If there are no signs of seams cracking the paint on the topsides then should be OK.

There's no reason for the frames to be affected and they will almost certainly be at ambient humidity anyway, being in the shade and under cover.

Boats on swinging moorings expose each side in turn to the sun and wind with each change of tide; boats in marinas can "cook" one side.

Open seams are inevitable if you use a dark colour.

White is the prudent colour...

We have not experienced any trouble with our Finesse - Iroko-planked, white painted top sides - even though she is on a drying trot mooring and has her port side exposed to the afternoon sun. I accept the fact that the exposed varnished coamings, rails, cabin sides and fronts are getting a hammering from the UV.
The Redwing being dry-sailed is more of a worry and I have tried to keep her in a shady spot. Again, being planked in hardwood (Agba) helps; spruce-planked Redwings always open up and get leaky in hot weather.
