Kevin's right -- sometimes you gotta bite the bullet and punch those holes into the deck. Here are some hard-and-fast rules to insure you get those bubbles out:
1. Make the vent holes at least 1/8" in diameter (too small and surface tension between the bubble and water will be strong enough to prevent escape of the air)
2. Bevel under the hole to minimize the thickness of the holes bore
3. And grease the underside of the deck to keep bubbles from clinging to the underside of the deck (the grease reduces the air-bubbles ability to 'stick' to the underside of the deck).
