Ah, good points. Makes sense....will leave that part out. Also foam is messy. Planning to glass and resin coat the new beams. Have one beam rotted through, one that is a bit too springy for me when i walk on it, so will replace all. Plus am engineering a carbon fiber clamping mast tabernacle to bind my unstayed mast to the beam, and it will be easier to work off the planar surfaces of a trapazoidal box beam.

<p>IMHO, adding foam the the interior of the beam is not a good idea. It will add negligible strength and will tend to trap moisture. Think of it as putting the cling wrap on the inside of the beam.</p>

<p>In order to add torsional strength to the beam, the foam will have to resist both tension and compression, something foam is not known to do.</p>
