Here are a few thoughts in no particular order:
1-anything visible above the waterline in winds like that = "windage" Reduce the boat's profile in any way you can. Remove all sails
and stow below. Remove canvas
and stow below. Take down wind vane
reflectors and anything else on deck
that you care to see again. Remove flags
and deflate the dingy and stow it. Tighten all your halyards or better yet, attach them to a down guy and haul them all to the masthead. Batten down the hatches!
2-I would fill the fuel
and water tanks
. You may find yourself motoring and the extra weight down low can help in the boats stability.
3-You'll need to asses the anchor/s on board and all the ground tackle. Note If you have multiple hooks, chain and or nylon rode
and that any shackles look strong.
4-picking a good location to anchor can make or break your day. If you know ahead what direction the strong winds will be coming from anchor off a windward shore. ie: if they will be coming from the West... then anchor just east (to leeward) of land or an island that will block most of the wind.
5-if you have 2 anchors, set them both out in a V formation so that strong wind comes right down the middle of the "V"
6-Give the boat room to swing. Don't anchor 90 feet from shore with 150 feet of anchor line out. Try not to have any boats or land astern of you.
7-put out as much anchor rode
as you can. when the anchor bites, drive it into the bottom with full astern motoring.
8-after your anchor/s are set, back the motor
slow til the rodes stretch and note sideways ranges that you can use later to see if you've dragged. ie. line up that big tree in your eye site with the side of that building... when I look out the main window. In the storm in the dark you'll need to use a strong light to illuminate the range to see if you're holding
9-chafe on your anchor lines is a major concern. Make sure the anchor rode exits your bow cleanly and add leather or hose material at chafe points to protect the rode and boat.
10-an alternative way to anchor is to set your main anchor very well ... then attache a 2nd anchor to the main anchors chain about 20 feet from the main anchor... then set this anchor and then let out as much rode as you can... the 2nd anchor if set will help the lead on the first and this can work in a blow.
11-once the boat is set... decide if you are going to stay with her... there is no shame in not... there is probably insurance
for the boat... but what if you get hurt... or... worse
12-if you ARE going to stay on board, think safety! Have life jackets out.. WEAR THEM, Tethers. Run jack lines. Have a first aid kit handy. have flashlights with batteries. Before the storm eat and sleep if you can, rest and strength will be needed. Foul weather gear
will be needed. Towels and warm clothes... you'll be wet and cold. Layers, rain gear, boots, goggles! Rain stings your eyes at 65 kts. (hurricane strength as far as I'm concerned). wear a light- a strobe or those glow sticks. I'd have a buddy with me if I could convince one to stay with me.
13-listen to the forecast
. Have your phone
charged. if you have a smart phone
use weather and radar
14-I have weathered a blow by motoring straight into the wind (while anchored) to relieve the stress on the anchor line... One time we were running full speed ahead and just maintaining position.
15-Even with bare poles your boat will heal over in puffs and may veer left and right as the wind hits her... but if you're fairly close to a windward shore the waves should not grow too large and you should be okay. Check those ranges you created before to make sure you're holding.
16-Have a bailout plan... if the anchor does drag, know your location and where you might try to go if the wind shifts or the ***** hits the fan... consider a nice sandy beach that you could run aground on and get your arse to shore.
17-Wind that strong is loud... make sure you communicate with your buddy/s before doing anything so that everyone is on the same page... you may need to use hand signals... go over them in advance.
18- Ride that storm out Brother! In the middle of it you will be keenly aware that you ARE ALIVE! Stay that way!
19 - after the storm abates, assess your situation and buy that buddy a top shelf rum
20- Go rent a slip at a marina for next time!
