You could try closing the seacocks and pouringour biodegradeable antifreeze into the drains until they filled to the cockpit level. If the cockpit is uncovered, you''ll have to shovel out the cockpit each time it snows. If it rains, you''ll have to drain the cockpit to get the water out and repeat the process.
