varnish
i keep my boat wet year round, so in the winter months i have plenty of time to do interior work..a couple of years ago,tired of oiling,i took the plunge and varnishrd the interior of my 28.5..i really cheated,just a little sanding and i mean a little,pulled out the brush and stoked on a nice high gloss finish...put on two coats..still looks better than any oil finish i ever had..if i was to do it again i would use a water base varnish such as j e moser,s marineshield..dries in an hour and ready to re-coat
