I hope you dont mind Dennis..but the phrase “it was quite rough but we managed to stay very dry” always makes me smile me when I read it with regards to small inflatable boats
Simply because if true .. it tells me that it wasn’t that rough or if it was choppy water..the wind was not the cause of it!!
I have been in car ferries in the rough and water comes over the side in certain conditions. Large RIBs and I have been soaked to the skin. Popular brands of fishing boats like Warriors and Alaska’s .. and the water is flying everywhere.
The Honwave in “quite rough” water is a wet boat despite your claims it is not..but it all boils down to what you think is rough.. a bit like that infamous Solent..which many think is the roughest water in the UK.
HonwaveT38 in a little rough stretch of Scottish water. It had plenty in the boat when we finally landed.
Only yesterday I was going round Borrowhead in the Solway firth in a F4 verging F5 with wind against tide and its a seven mile long stretch of coast with tide running at 4 knots.. I doubt your “quite rough” was the equivalent but I may be wrong. ?
Excel Volaire
But to answer your question The Excel Volaire I was with ships less water than the Honwave T38IE in many conditions..but if the wind is blowing the flying spray around..they probably ship around the same amount.
Why ? The Excel planes around half way along its length ..where the draggy Honwave planes much further forward.. which from my view running ...beside them ..makes it the wetter boat.
However no skipper gets wet on our quite rough seas.. simply because we wear drysuits..its the only sensible answer for boat wear in small wet boats
Hope that helps answer your question
