As an alternative to hiring a crane to come down to the beach to retrieve the
boat I'd echo what
edlithgow suggests and start by putting out a kedge (an anchor) on a nylon rode (rope) to seaward. In fact, I'd suggest using two - one at a stern
winch that you can tighten to put 'spring' in the rode, and one at the bow to keep the boat from pivoting. If you can - consider putting the stern
rope under the boat to a lower
deck winch instead of on the upper
deck winch. That way - it won't tend to turn the boat onto its keel as it is pulled downslope.
The tides for the past several weeks have been lower than those that you'll see in the next few days - so be ready to try to move the boat soon - or at least, try to keep it from being pushed up farther onto the bar. The next couple of days will see the higher high tides (Port Angeles has mixed semidiurnal tides) of 7.97' occurring at 3:51 pm on the 9th and at 4:15 pm on the 10th. Those are the best times this month to get things moving. Otherwise, you'll have to wait until November 4 for a similar tide height when the higher high tide will be 8.1' at 12:37 pm.
Again, as
edlithgow says, rollers are not the greatest thing. They tend not to roll on sand. Instead, try to slip, say, lengths of 4" or 6" schedule 40 PVC pipe (schedule 80 is stronger - but it is more expensive and not as easy to obtain) under the boat as it is lifted by waves at high tide. The pipe will be placed perpendicular to the boat - so the boat will slide down the pipe. Be prepared for the pipe to be buried into the sand - so don't be irritated (too much). Smooth
logs or even 4x4s or 6x6s may also
work, but they are heavier and more difficult to move. Perhaps even think about wedging lengths of
plywood under the boat. You need something that will spread the weight of the boat on the sand - and also that will allow the boat to slide back into deeper
water without building a wedge of sand downslope of the boat as it slides. In any case - make sure to put something under the bottom of the keel so it won't dig into the sand as it slides.
As far as what kind of boat it is ... look for the
Hull Identification Number (HIN) - similar to the VIN on your car. If the boat was launched more recently than November 1972 it will have one - and they are usually inset at the upper starboard side of the boat's transom. The format is generally "ABCXXXXXYYYY" where the "ABC" is the manufacturer's identification code and "YYYY" indicates when the boat was launched. You can go online and look up the HIN to see what firm manufactured the boat and how to interpret the launch date.
Good luck.
