If we take the average speed of a laser at 10 knots...
I'd be looking for more frequent boltholes. I owned a laser for years, just because they're quick and light does not equate to a 10 knot average working a coastline. Dunno how light they'd be loaded up for passage making.
Use VMG not boat speed, a 10 knot average at 45 TWA is more like 7 knots. Your 200km span then equates to 30 hours, not 14-16 and I'd be pretty rooted after maintaining 10knots on a laser for 30 hours.
And that's if you maintain a 10knot average, which never happens for sustained periods unless the gods are really smiling on you.
Ring Tidetech and have a chat to them to see if they've mapped most of your route, if they cover the area of interest buy a subscription. The first thing I'd be looking for is tide and current influences as you will be restricted in a Laser on how far offshore you can go to get in and out of favourable conditions.
I've spent hours trying to get round bloody headlands with the end result often being backwards, that's when a motor is your best friend, not really an option on a Laser.
And no, you don't park off a beach in a keelboat either. It's either push through or heave to, nether of which is comfortable anywhere near shore. Hence you dig out to sea to give yourself room, another avenue not really practical for you.
Chat to lots of locals and keep doing your research.
All the best,
